West Valley Floor Professional Guide
Detailed Trail Description from our Guidebook
"This is a longer hike, but there is little elevation change. Start early, take a picnic, and make a day of it. Along the way are opportunities for swimming or wading, good places to watch the climbers on the face of El Capitan (especially with binoculars), and fine views of several famous waterfalls in spring and early summer.
The falls are mostly dry by mid-August. The valley floor can get hot in summer, but most of the trail is in the shade."
