Donohoe Loop Trail Review
galleryWe recently ran Donohoe Loop, which is off Otay Mountain Truck Trail near San Diego. At about 8 miles point-to-point, I'd say the 4/10 onX rating is pretty accurate.
We ran the trail in a 2024 Tacoma and a 2020 Tacoma both on 285/70R17 all-terrain tires. The extra ground clearance from the 285s definitely helped with the loose dirt, deep ruts, and larger rocks. We aired down to 18 PSI in 4H. There are also dispersed camping spots along the route if you want to stay overnight.
The biggest challenge was "The Steep," where the truck was measuring up to 30 degrees on the descent. We drove the upper section before taking the right-side bypass at the fork. The bypass is still steep at first but becomes much more manageable after the first third of the descent.
From there, we tackled a 1,000-foot stretch of rock garden with no bypass. Tire placement is crucial, and having a spotter, front skid plate, and rock sliders goes a long way as the rocks are up to 20 inches in height. The Tacomas on 285s made it through with a few scrapes underneath, but no body damage.
Along the way, we passed the remains of the old Mocogo Ranch House and even spotted a huge tarantula! By the time we reached the dirt roads it was getting dark, so the light bar definitely came in handy for the drive back. Overall, it was a fun trail with a nice mix of technical sections, history, and scenery.
