Cougar Canyon (Anza Borrego Desert)

Cougar Canyon is a unique canyon located in a remote area of the Anza-Borrego Desert State Park that is fed by a mountain spring that flows all year around. This is a true palm-filled oasis in the middle of a scorching desert. This canyon was first descended by Chris Brennen (see beta reference) and has been rarely descended since then due to the difficult access logistics. Chris descended the canyon by setting up a long shuttle and camping at the Los Coyotes Indian Reservation, an option that is no longer available nor recommended. There is a dirt track that goes all the way to Sheep Camp, only a few minutes walk from the mouth of Cougar Canyon; however, the quality varies greatly from year to year, depending on recent flooding and maintenance by the park. Currently, as of February 2026, a 2WD/low clearance vehicle can reach Desert Gardens, which is about a six mile walk from the mouth of Cougar. An SUV with clearance can reach Third Crossing, about a five mile walk from the mouth of Cougar. Third Crossing has a closed and locked vehicle gate, so the only way forward currently is on foot. Be sure to check Anza Borrego's website for current conditions. When hiking in, the preferred camping spot is the mouth of Cougar, where there are ample sandy campsites and dependable water. Sheep Camp has picnic tablets and an outhouse but no water. Because of these current conditions (February 2026), it's recommended to do Cougar as a two-night adventure.

You'll likely be parking near Desert Gardens or Third Crossing and then have a ~five mile gently uphill hike to the mouth of Cougar Canyon. From the mouth, start before dawn to head up Indian Canyon. There is a faint trail here that eventually disappears. Continue to follow the gully upstream, at times passing intermittent water and groves of palm trees. This area is called the Valley of the Ten Thousand Springs. Follow the GPS track. You'll eventually begin a steep and intense scramble up a mountain, bearing to climber's-left of a prominent rock outcrop. From the saddle, climb down into the canyon. The first rappel is a few minutes downstream. With this approach we deliberately omitted from the descent the upper technical section of the canyon (3 rappels). To include these one should follow the longer approach, which would add 2h-3h to the descent (not recommended).

Rangers state Cougar has flowing water every day of the year, although it's doubtful they've been there in August to confirm. Regardless, in winter and spring, flows should be plentiful. A wetsuit is recommended for most canyoneers - even on a beautiful 80F day, the water is quite cold, and the canyon is completely in the shade without any direct sunlight from late October to late February. The descent has around 13 rappels, with quite a bit of boulder hopping and bushwhacking. One rappel, in the narrows, has two ol (placed 2001?) but sturdy pitons. All others use webbing, which may be easily washed away when the canyon floods every few years. All partied should carry some webbing, a knife and a few rapides. There is ample material to build natural anchors if needed. You may need to use retrievable anchors if you run out of webbing (http://www.canyoneeringusa.com/techtips/tworingretrievableanchor/). Please try to NOT just sling rope around a tree and pull down from there. I know it's easy and cheap, but if many people did that the tree would die. Many rappels are in the flow, although the flow should never create any dangers like hydraulics. Some years, pools fill with sand; other years, they're full-on swimmers. The final rappel drops you in a pool at the edge of the Psychedelic Eye (1970s rock art) which marks the end of the technical canyon at elevation 2020ft. The Eye is hidden behind a big boulder on canyon right, you won't see it until you are right in front of it. From here, it's still a bit of bushwhacking and boulder hopping to get out of the canyon and back to the desert floor. The descent is well documented by Chris Brennen, just skip the first section of narrows (3 rappels) and everything is more or less still valid. However, Chris team exited the canyon after 10h at elevation 2360ft, that is right before the set of narrows above the Psychedelic Eye. These narrows are exceptionally beautiful and present 4 more raps that are a bit technical, but have good anchors from tree and pitons.

After the final rappel, follow the creek down with bushwhacking and plentiful boulder-hopping to the mouth of Cougar, and follow the trail you came in on back to your vehicle.
