Planning a Trip to Yosemite

[StackedOus]

Trying to plan a trip to Yosemite with some friends, but not sure if you need a permit to hike the trails, or if they are for lodging and special activities. If anyone has been there recently, and can share some insight, that would be much appreciated.

Avoiding the crowds is the biggest challenge. 

Yosemite is a wonderful place to visit but timing is everything.
