Not to be confused with Devil’s Canyon in the San Gabriel Mountains, Devil Canyon of Chatsworth is an understandably popular destination, due to its seclusion, scenic variety and proximity to the Valley. While many hikers enjoy exploring the jungle-like confines of the lower canyon with its numerous sandstone caves and other geological formations, the pastoral upper reaches of the canyon, consisting of rolling hills, oak woodlands and ultimately excellent city and mountain views, are also worth a look. “Afoot and Afield: Los Angeles County” and several online writeups of the hike describe a gate 2.3 miles into the canyon, blocking off progress, but as of this writing, the gate is no longer there, allowing hikers to go as far as they want. The entire 10-mile round trip with its easy slope and ample shade is an enjoyable and efficient training hike.

0:02 – Start of the Santa Susana/Devil Canyon trail (times are approximate)

While access to the canyon has changed and may change again in the years to come, it can currently be reached by walking through the parking lot of a private condo complex on N. Poema Place. As this is private property, access to the trail cannot be guaranteed, but it is likely that hikers who exercise common sense and don’t create a disturbance will not be given difficulty by residents. Bear right at the first major “intersection” (by building 11504) and you’ll see an open metal gate with a staircase descending steeply. The staircase drops to short use spur leads you to the main trail, signed here as the Santa Susana Pass Trail. Bear left and continue your descent into Devil’s Canyon, arriving at the floor in about 0.3 miles.

0:38 – Following the stream bed

From here, make your way up canyon, keeping an eye out for poison oak which frequently encroaches the trail, sometimes from both sides at once. If the water level is high, some of the stream crossings can be tricky and the trail follows the stream bed itself from time to time, but while it is a little overgrown in some places, it’s fairly easy to follow; if you find yourself bushwhacking, you’ve likely strayed from the course.

0:44 – Nice spot for a picnic

At 1.3 miles, bear right as a trail steeply ascends to the left. You briefly follow the stream before emerging into an attractive wooded area where several rocks and logs make it a nice place for a break. Soon after, the trail emerges into the open, passing a junction with Ybarra Canyon (1.9 miles.) After passing over a concrete flood dam, the trail continues through more scenic terrain, in and out of shade. Poison oak, while still present, isn’t as much of an issue from here on out.

1:25 – Passing through a fence

At 3.3 miles, the trail enters a meadow and bears northwest, climbing briefly away from the stream bed. You pass by a particularly impressive oak that makes a good turnaround point if you’re short on time and continue, ascending slightly more steadily, into another pocket of trees, crossing a tributary of Devil Canyon (4 3/4 miles) and finally making the final climb to the trail’s end at the Brown Mountain Fire Road.

Not to be confused with Wildwood Park in Thousand Oaks, Santa Clarita’s Wildwood Canyon Park (also known as Wildwood Canyon Open Space) is a 95-acre open space nestled between the 5 and 14 Freeways. Compared to Santa Clarita’s other nature parks, Wildwood feels more like wilderness, in part due to the variety of plant life (oaks, manzanitas, chaparral and more) and also due to the somewhat confusing network of official and unofficial trails and lack of signage distinguishing the two. The good news is that due to the park’s proximity to civilization and relatively small size it’s hard to get too seriously lost here and it’s a fun place to wander around without any specific agenda.

0:15 – View from the first junction; head straight down into the canyon (times are approximate)

Those who do want to follow an exact route however will enjoy the 3-mile hike described below, which circles the perimeter of the park on some of the more clearly, better maintained trails. From the trail head on Haskell Vista Lane, follow the path as it climbs uphill, making a series of switchbacks before gaining a ridge at half a mile where a panoramic view of the canyon awaits. It descends briefly to a junction with the Cross Motorway. Stay straight and descend into the canyon, reaching another intersection at 0.8 miles. This is the start of the loop which can be done in either direction. If it’s warm or hot, consider going counter-clockwise as described here, allowing you to save an enjoyable shaded stretch for last.

0:20 – Start of the loop portion of the hike

Continue straight and begin a steep ascent to a clearing with a trash can and a makeshift fire pit. As a detour, you can follow a use trail on the left down into an attractive wooded canyon but watch out for poison oak. The trail continues uphill, now marked as the Highland Trail on the official park map. It skirts the upper rim of the canyon, crossing two small wooden footbridges. Shortly after the second, you reach the highest spot on the route, signed as a vista point on the map, although there are no benches, shade structures or other facilities here. Still you can enjoy a nice view of the Santa Clarita Valley and the Sierra Pelona mountains beyond.

0:24 – Highland Loop steeply ascending past the picnic area

The trail continues past a junction with a spur that drops back into the canyon. Stay straight and begin descending, passing by a large red water tank and making a switchback. To the east, you can see the end of the San Gabriel Mountains towering beyond the buildings of the nearby Hart Museum and Ranch.

0:47 – Passing the water tank on the descent

At 2 miles, you reach the end of the Highland Loop Trail. Turn left and follow the trail into a grove of oaks. At dusk, this area is particularly attractive; but for the presence of some graffiti (and bugs during the evening) it would match up favorably against the best woodlands of the Santa Monica Mountains. Ignore a trail branching off to the left before exiting the woods and returning to the junction, completing the loop. Turn right and retrace your steps up to the other junction and back down the hill to Haskell View.

      • Location: Northwest San Bernardino Mountains between Hesperia and Lake Arrowhead. From I-15 in Hesperia, head east on Main Street for 7.2 miles. Just as the road bends south, take a right on Rock Springs Road, which becomes Roundup Way after 2.8 miles. Continue for 4.3 miles on Roundup Way (the last mile or so is dirt) and turn right on Bowen Ranch Road. Follow Bowen Ranch Road for a total of 5.4 miles to the signed entrance to the ranch (stay right at the junctions with Coxey Creek Road and Oak Hill Road). The road is overall in decent condition but there are a few rough spots; high clearance and 4WD vehicles are best but not required. After paying a $5 per person fee (or $10 per person for overnight use) continue 0.7 miles to the trail head. As of this writing, the last few hundred yards of the road are in rough condition so if you’re uncomfortable taking your car over it, you can park in a small turnout shortly before and walk the rest of the way. Trail head coordinates are N 34 21.510, W 117 09.881.

Deep Creek Hot Springs Trail Head, Bowen Ranch, San Bernardino County, CA

0:00 – Trail head (click thumbnails to see the full sized versions)

The most popular way to reach Deep Creek Hot Springs is from the north, starting at Bowen Ranch. This route is also the easiest, covering the shortest distance and the least amount of elevation gain compared to the routes via the Pacific Crest Trail and Bradford Ridge. It is also arguably the most scenically interesting, providing dramatic views of the creek on the descent. There are a few caveats, though: the descent is steep and exposed, often over somewhat loose terrain. Temperatures in the area can be notoriously hot, making for difficult ascents from the springs for those who don’t plan accordingly. Getting to the trail head is somewhat tricky, requiring almost seven miles of driving on dirt roads. This is also the only route that requires payment; $5 per person (not per vehicle). Lastly, unlike the other two approaches, this one requires fording Deep Creek to visit the hot springs. If the water levels are low, the creek is fairly easy to traverse but caution should still be exercised. Despite these potential challenges, this is an enjoyable hike to a unique destination; its popularity is understandable.

From the parking area, follow the trail south. You soon reach an overlook with a pair of interpretive plaques that sadly have been vandalized beyond the point of recognition. There is, however, an impressive view of the eastern San Gabriel summits (Baldy, Telegraph, etc) and of the western San Bernardino Mountains.

At 0.3 miles, the trail drops sharply, making a steep descent over loose terrain into a wash. At the bottom, bear right and follow the trail to a dirt road. Turn left, walk a few hundred feet to an alternate trail head (0.5 miles from the start) and begin hiking the “official” Deep Creek trail, signed 3W02.

0:16 – Bear right on the trail after leaving the dirt road

You follow the trail through a canyon, getting a glimpse of Deep Creek’s gorge at about 0.8 miles. Vegetation includes mesquite, Manzanita and cat’s claw. At 1.1 miles, you get your first view of the creek itself, cutting its serpentine path through the mountains. From here, the trail begins another steep descent, making a switchback that provides an impressive view to the west and finally dropping to the sandy shores of Deep Creek (1.8 miles.) The year-round stream supports a diverse array of plants, including cottonwoods, sycamores and even a lone pine.

If you are nervous about crossing the creek, this can be a nice spot to sit and enjoy the scenery before heading back. Adventurous hikers can wade through water that is likely to be at least knee-high to the pools on the south side of the creek.

This is arguably the most popular day hike out of Warner Springs, with the possible exception of Eagle Rock. It follows a pleasant stretch of the P.C.T. as it heads north from Highway 79, paralleling Agua Caliente Creek, which usually flows year round. While the scenery isn’t quite as dramatic as it is on the way to Eagle Rock, this section of the Pacific Crest Trail still offers a nice cross-section of the landscape around Warner Springs. The 9.4-mile round trip described here is a good, moderate day hike, but it can easily be shortened or extended.

Vegetation along this stretch includes beavertail and cholla cacti, yuccas, manzanita and oak. You reach a saddle (3 miles) where the trail descends back to the creek (3.3 miles) passing by a makeshift trail camp.

The trail briefly climbs the west side of the creek before dropping back down. At about 4 miles, you pass a wall of granite. At 4.6 miles, the trail enters a sloping meadow and soon after, you reach another trail camp; a perfect spot to relax beneath the oaks, accompanied by the sound of the trickling stream.

Eaton Canyon Natural Area in Pasadena is best known as an access point for the lower end of the Mt. Wilson Toll Road and for its popular (and infamous) waterfall. However, hikers shouldn’t overlook the Horse Trail, which provides a short but vigorous workout with some panoramic mountain and city views. Best done on cool days with good visibility, the vistas from the Horse Trail include the Santa Monica Mountains, Catalina Island, Old Saddleback and a nearly aerial perspective on the residential areas of the north San Gabriel Valley.

0:09 – Oak woodlands (times are approximate)

The network of trails through and around the nature center invite meandering and exploring, but for the purposes of this post, the most direct route involves a pleasant 0.6 mile stroll along the park’s main trail followed by a climb of 0.6 miles on the Horse Trail to its upper end at the toll road. From the parking area, take the right trail (the left leads to a picnic area with water fountains for both human and canine hikers) and follow it past fields of spring flowers with the mountains making an impressive backdrop.

0:18 – Start of the Horse Trail

At 0.25 miles, cross the stream (dry as of this writing) and enter a pleasant woodland, ignoring several trails that branch to the right. Continue north, ascending gradually, making your way in and out of pockets of oaks. Poison oak, while not hugely prevalent, is found along the sides of the trail. At 0.6 miles where the main route continues north toward the waterfall, turn right on the Horse Trail which begins its efficient climb up the canyon’s east wall. The trail is largely exposed, although a few pleasant spots do provide some shade. About half way up is a spot with some excellent views, including downtown Los Angeles.

Shortly before the top of the trail, look for a pleasant pine grove (a miniature version of Henninger Flats, farther up the toll road). This is an excellent spot to sit and rest, especially if the day is hot. Between the trees, glimpses of downtown, the Palos Verdes Peninsula, Signal Hill and more can be seen. Shortly beyond this point, the trail makes one final switchback before meeting the toll road. Ambitious hikers can continue uphill another two miles or so to Henninger Flats, while those who want some variety on the descent can make a loop by descending the toll road and following the Eaton Canyon Trail back to the nature center.

In addition to being Orange County’s oldest public park (1887), Irvine Regional Park is home to the O.C. Zoo, a miniature railroad, several nice picnic areas and for the purposes of this website, a number of hiking trails. The trails loop around the park, heading northwest to Santiago Oaks Regional Park and south to Peters Canyon Regional Park, making for endless possible routes of all lengths. While Irvine isn’t as isolated as Caspers, Whiting Ranch and some of Orange County’s other regional parks, it still offers a nice variety of scenery, a convenient escape from city life. Though it may be hot during the summer, the hills and distances are moderate enough for it to be considered a year-round hiking destination.

This post follows the route as described in “Afoot and Afield”, mainly utilizing the park’s popular Horseshoe Loop Trail; also the Toyon Trail and some paved service and access roads. Hikers on a tight time frame should be able to easily knock it off in an hour; those hiking with small kids or dogs (this is one of the few dog-friendly regional parks in O.C.) should allow an hour an a half to follow this route.

From lot #7, head left on the paved road and pick up the trail on the right, heading uphill between two wooden fences. You soon reach a junction with the Horseshoe Loop Trail where you’ll turn left and then almost immediately left again as the Puma Ridge Trail heads uphill. Follow the Horseshoe Trail along a north-facing ridge, enjoying views of the Santa Ana Mountains. In the spring, the grass and wildflowers can be quite attractive and considering that you are only about one hundred feet above the basin of the park, the views are quite wide-ranging.

0:32 – Rejoining the park road; trail follows parallel on the right

More climbing brings you to a vista point (0.8 miles) where you can sit on a bench beneath a pine or under a shade structure. From here, the trail descends to cross a private service road (1.1 miles) and soon after joins the main road, which it parallels for 0.2 miles to the last parking lot. The road, still paved but now closed to the public, heads north and then west, skirting the park’s boundary.

Rooster Rock, Irvine Regional Park, Orange County, CA

0:50 – Rooster Rock

At 1.8 miles, the northern branch of the Horseshoe Trail splits off to the right, heading uphill. Take a short detour to Rooster Rock, a sandstone formation likely named for its outcrops that resemble poultry beaks and combs. A pair of oaks provide nice shade beneath the rock while a few use trails allow the curious to explore the top of the formation, which offers a bird’s eye view of this area of the park.

After visiting Rooster Rock, head back and follow the Horseshoe Trail as it makes its way up a hillside to a junction. The two paths soon merge again, although the right fork climbs higher and offers better views. From here, the trail levels out, contouring along the north side of the park to a junction at 2.3 miles. This is the Toyon Trail, which descends to a shade structure and then follows a wooden staircase back down to the center of the park. Head right on the paved road and follow as it passes a picnic area, the railroad tracks and a small lake before ending at a T-junction. Turn right and follow the main road back to the parking area.

The destination is Coquina Mine, a limestone quarry that was abandoned in the 1930s, although the expansive network of trails in Marr Ranch Open Space, Las Llajas (YA-has) make it easy to extend the hike.

From the Las Llajas trail head, follow the paved road to a T-junction. Bear right and descend into Las Llajas Canyon. The road becomes dirt and you follow it for an attractive if not terribly varied 1.5 miles or so, passing a few private inholdings and private roads branching off, including a bee colony about 1.1 miles from the trail head. As you head up the canyon, keep an eye out for interesting limestone formations on the hills above. If there have been recent rains, the sounds of a seasonal stream accompanies your walk.

At 1.8 miles, shortly after the trail crosses the stream, look for a faint but unambiguous single-track trail branching off to the left. The trail begins a steep, crooked ascent, clinging to the hillside, providing a nice aerial view of Las Llajas Canyon. After 0.6 miles of steady climbing, the trail briefly levels out. You pass by some rusting mining equipment as the trail winds around the north side of a ridge.

At 2.7 miles, you reach a T-junction. Follow the trail as it makes a hard left, climbing a few more switchbacks with excellent views to the south of Simi Valley, the Simi Hills and the Santa Monica Mountains. As you pass by an abandoned engine on the left side of the trail, you’ll also notice a large steam shovel perched on the hill in the distance; that is the destination. At another T-junction, turn left and walk the last few yards to the steam shovel. Shortly beyond it, you get an outstanding view which includes Anacapa and Santa Cruz Islands. In the distance to the north is the round, antenna-covered summit of Oat Mountain, the highest peak in the immediate area.

After enjoying the view, retrace your steps. If you want to extend the hike, you can walk farther up Las Llajas Canyon; back at the first T-junction, you can also explore more by following the vague path to the right. This reaches a saddle where you can climb to a vista point with more all-encompassing views.
