The long but easily graded Guadalasca Trail is one of Point Mugu State Park’s more enjoyable routes. It’s popular with mountain bikers (expect to see a few on the trail) but due to its remote location within the park, it can be tricky to do as a day hike. The easiest way to hike the Guadalasca Trail is the trip described here; a “balloon” type hike consisting of a 2.6-mile out and back segment and a 4.9-mile loop.
Starting at the Ray Miller Trailhead, take the La Jolla Canyon Trail north. As of this writing the park is still recovering from the effects of the 2013 Spring Fire. New growth is starting to take place but the area is still largely dry and burned.
At about 0.7 miles, you pass by a small, two-tiered seasonal waterfall. Unless there have been recent heavy rains, don’t expect much from the waterfall, although at this point, where a tributary joins La Jolla Canyon, the trail starts to feel more rugged and remote. You climb into the narrow canyon, clinging to the east wall. A few burned stumps of coreopsis plants can be seen poking up through the rocks; hopefully future wet seasons will help bring them back into bloom. Sadly, graffiti and trash take away from the appeal of this section of the trail; while most people come to Point Mugu and other parks to enjoy nature, keep an eye out for those who might not have such a worthwhile reason for being here.
At 1.2 miles (and almost 600 feet of elevation gain) you reach a Y-shaped split. The left fork heads toward Mugu Peak, but our route heads right, toward La Jolla Valley. Things get a little easier here as the trail grade levels out considerably and chaparral and scrub oaks provide shade. At about 1.7 miles, you get a nice view of La Jolla Valley to the left, pleasantly green with spring rains, contrasting the burnt hills around it.
Soon after you reach another split where you stay right. At 2.4 miles, turn right on the La Jolla Fire Road and follow it uphill 0.2 miles to a four-way junction; the start of the loop. Hiking the loop counter-clockwise, as described here, will spare you having to ascend the appropriately nick-named Hell Hill (650 feet elevation change in 0.8 miles.)
As you descend Hell Hill, you’ll get a nice view of Boney Mountain and the northern end of Sycamore Canyon. At the bottom of the steep road, turn left on the Wood Canyon Fire Road and head north for a pleasant 0.3 miles beneath the shade of some oaks to the lower end of the Guadalasca Trail.
The first part of the Guadalasca Trail follows a wooded tributary of Wood Canyon; then it climbs into an open area. At 4.5 miles from the start, bear left at a fork. You cross the shallow canyon and start a long, gradual ascent. A solitary oak marks the approximate halfway point of the hike and makes a good rest spot.
Past the oak, the trail makes a few long switchbacks, providing good views of Boney Mountain, the Ventura coastal plain and the northern end of the park. If visibility is good, you may be able to see Ojai’s Topatopa Mountains.
At 6.2 miles, the trail becomes an abandoned fire road. Bear left and continue ascending briefly to a vista point (the high point of the hike) at 6.5 miles, where you can get a nice aerial view of La Jolla Canyon and a little slice of ocean. From here, the trail gradually descends a mile back to the junction with the Overlook Fire Road. Turn right and retrace your steps back to the Ray Miller Trailhead.
