San Diego waterfalls are real but seasonal: they run hard from January through April after winter rain and mostly vanish by summer, and the two best ones both require a free permit.

The best waterfall hikes near San Diego are Cedar Creek Falls near Ramona and Three Sisters Falls near Descanso — both require a free Recreation.gov permit and both flow best January through April.

San Diego's waterfalls are rain-fed, not spring-fed. The sweet spot is roughly one to two weeks after a solid storm, when the creeks are full but the trails have dried out. Check recent trip reports before driving an hour east — a dry December means a dry January.

Cedar Creek Falls and Three Sisters Falls both require a free U.S. Forest Service day-use permit reserved through Recreation.gov, with limited daily quotas.
