You have to purchase a pass to go into the park system and you also need a permit to go camping. I think it's $20 a day and probably $40 overnight. There are several campsites and campgrounds available. Your first stop should be the Visitor's Service Center here in Jackson, it's a corporative between all the different agencies like the wildlife agencies, the Forestry Service, the Jackson Hole Chamber of Commerce. It's very interactive. They can give you a complete guide to anywhere you want to go. You can call ahead of the time - the Visitor's Services Center is housed at the Chamber of Commerce. They will give you all the names of the campgrounds and prices.
