Three Sisters Falls

  • Location: Cleveland National Forest between Descanso and Julian, San Diego County. From I-8, take the Highway 79 exit (40) and head north for 1.3 miles. Turn left on Riverside Drive and go 0.9 mile to the “downtown” area of Descanso. At the market, turn left on Viejas Grade and make an immediate right on Oak Grove Drive. In 1.6 mile, turn right onto Boulder Creek Road. You will follow this road a total of 13 miles to the trail head. The first five miles are paved and the last 8 are dirt/gravel, but passable for all cars despite a few rough spots. There are a few spots that can become flooded following recent rains. The trail head is at a hairpin turn in the road and is well signed (you will probably see at least one other car parked here). Alternately from Highway 79 in Julian, take Pine Hills Rd. south for 1.6 miles. Turn right onto Eagle Peak Rd. and go 1.4 miles. Bear left onto Boulder Creek Road, following it for a total of 8.4 miles to the trail head. Until recently a National Forest Service adventure pass ($5 per day or $30 per year) was required for parking here; because there are no facilities at the trailhead, passes are no longer required. (For a list of sites in the Cleveland National Forest that still require the pass, click here. If you would like to purchase a pass just to be sure, or to use at other sites, click here).

It’s one of San Diego County’s most popular, adventurous and in some circles infamous hikes. It features panoramic mountain views, riparian habitats, exposed slopes, a steep and rocky descent and ascent, boulder scrambling and a waterfall that is not to be missed after heavy rains–all in two miles each way. It is Three Sisters Falls and it is hike #900 to be posted on this website.

Like nearby Cedar Creek Falls, Three Sisters requires hikers to know what they are getting themselves into. According to this article, five helicopter rescues were made between the two waterfalls in one day in June, 2016. While both waterfalls are reverse hikes (down than up) in area that often sees triple digit temperatures during the summer, Three Sisters has the added challenge of a very steep and loose descent and more difficult boulder scrambling to get to the falls. That said, well-prepared hikers who make the trek will be amazed, especially during wet winters. When the falls are at full blast, they are stunning; even if they aren’t at their peak, the variety of scenery and the sense of adventure (and bragging rights) are worth the effort to reach and complete this hike.

The trail starts off innocently enough (despite three posted signs with dire warnings about the conditions ahead). You follow an abandoned service road along a ridge, enjoying views of Eagle Peak straight ahead and the Cuyamaca Mountains behind. You may be able to pick out the Santa Anas in the distance, far off to the northwest. After passing a knoll dotted with oaks, the trail descends to a saddle about 2/3 of a mile from the start. You should be able to hear and see the waterfall by this point.

Take a hard left on a somewhat obscure trail that descends along the slope, soon reaching Sheep Camp Creek (1 mile from the start.) The shaded stretch of trail along the creek is the most peaceful part of the hike. You follow the trail to a saddle (1.3 miles) with a wide area that could be a good spot for camping. The trail skirts the edge of the canyon for another 0.1 mile before the steep descent begins.

In the next 0.3 mile, you drop almost 500 feet down a rocky (sometimes wet) slope, aided by four ropes that have been left by volunteers. (If you are wary of the ropes and you are willing to use your hands and your ‘fifth limb’ then you may be able to make your way down without them). The last two ropes, though shorter, are the most treacherous as the terrain is likely to be wetter than higher up on the exposed hillside.

At the bottom, you can rest on a boulder at a pleasant clearing beneath two oaks. Head upstream (left) toward the sound of the waterfalls. At this point, the best route may depend on the water level of Boulder Creek. It’s possible to navigate the east side (stream on your right) of the canyon without crossing the stream on a network of use trails that have been beaten into the ground. You can also wade through sections of the creek, but it may well be waist-high. Whether you ford the creek or stick to the higher route, expect to engage in some boulder-hopping over the next 0.2 mile.

Depending on your chosen route, you will probably end up between the lower and middle sisters. The middle is the tallest, dropping about 50 feet into a large pool. With the cascading water on one side and a dramatic view down the canyon on the other, this is a good spot to rest up for the steep ascent back. Intrepid hikers who can negotiate rocky slopes that are likely to be slippery can make it to the base, or even the top, of the next waterfall, but that is only advisable for the experienced and skilled. If you do decide to climb higher, make sure you keep energy for the strenuous return.

  1. Could you tell me where you got your information that a parking pass is required? I’ve done that hike a couple times in the past and never needed a parking pass. And after seeing several sites saying I need one, I called the Cleveland National Forest office to ask, and they said you don’t need a parking pass because the Three Sisters hike isn’t in their jurisdiction. I want to follow the rules, and will get a pass if it’s needed, but I don’t see any official place that says it’s necessary. It’s only the bloggers that are saying it is.

    1. I got my info from the latest edition of California Hiking (2015) but I did some research and you’re right, apparently the pass is no longer needed. (I came across a list of the trail heads / sites that still do require the pass and Three Sisters was not on it). I have updated the post accordingly.

      1. Great, thanks for getting back to me about it so quickly! I’m organizing for a group hike for tomorrow, and I didn’t want to either make people pay for passes if they didn’t need them OR tell them they didn’t need passes and then they get ticketed. 🙂

      2. You’re welcome, thank you for reading the blog and bringing that question to my attention. Have a safe & fun hike and feel free to share pictures on the NHLA Facebook page. 🙂
