^ I went swimming at the base of Courthouse Falls last month.... Accessible via forest service roads off 215.
Nothing quite like doing the backstroke as you look up at blue sky and puffy clouds through the canopy, water crashing down in front of you. Cold water, but an unforgettable experience.
Ah, I've never actually been to Courthouse. Nice.
Edit//that's just on the other side of 215 from Dill Falls, and only about 10 minutes from the lodge.
