I'm afraid April is a bit of a risky month to visit Yosemite park if you want to hike a bit and see the waterfalls, since some of the roads can still be closed due to snow. May and June are incredible if you're looking for strong streams and green trees.. anyways- you'll always find beautiful scenery, no matter when you visit, the place is magical.
