San Diego River Trail Professional Guide
Detailed Trail Description from our Guidebook
"A trip down the upper San Diego River canyon during the rainy season is a true adventure. Runoff from winter storms fills the rocky riverbed with a silvery band of water. Green grass, new leaves, and wildflowers (appearing by February or March) brighten the banks as well as the slopes. In several places along the way the stream cascades over rock precipices, including one with a drop of 100 feet. Sturdy boots and a patient, cautious attitude are essential for this trip. By April or May, when hungry and irritable rattlesnakes emerge from their wintertime burrows, you’ll have to be extra vigilant. Long pants are recommended, as are small clippers to prune back the branches of poison oak in a few tight spots. If you’re traveling with a heavy or awkward pack, bring a 30-foot length of cord to assist in lowering it over rock faces as you detour around the waterfalls. Avoid the canyon after intense storms, when high water levels may make stream crossings difficult or dangerous. Get an early start if you are planning to thoroughly explore the canyon."
