I can't believe no one has started a thread on Yosemite yet!
I come from a climbing background so maybe that's why it's more high-profile to me. Is the valley not also renowned for its hiking as it is for its climbing?
Any favorite hikes?
Tuolumne Meadows is great. For more casual hikes starting in the valley Half-dome is an obvious choice, but I enjoyed Yosemite falls more.
