Yosemite Falls access and rafting on the Merced are the two big draws to this campground. This is one of the most popular parks in the world, so expect lots of people. It's hard to make a reservation; so you'll have to work pretty hard to get a spot. Go to www.recreation.gov and search for Upper Pines for more info. The campground is well-equipped and close to lots of great Yosemite attractions, and there is bus service throughout the park so you can visit the museum and the largest tree, etc.
