With nearly 27,000 acres, the national park is home to the largest region of old-growth bottomland hardwood forest in the southeast and some of the tallest trees on the East Coast. There is no charge to camp but a permit is required and visitors must leave their vehicles in the lot near the park entrance.

Located near the eastern border of Nevada and bounded by the Sierra Nevada and Wasatch Mountains, the 77,000-acre Great Basin is one of the National Park System's hidden gems. Due to its remote location, the park draws less than 100,000 visitors annually, a figure that can be eclipsed in mere days in the nation's most visited park – the Great Smoky Mountains. Nevertheless, those visitors who have made the trek to Great Basin are nearly universal in their praise, citing fresh mountain air, excellent hiking, the majestic Wheeler Peak and the remarkable marble and limestone formations within Lehman Cave. The park has five developed campgrounds and one primitive campground available on a first-come, first-served basis, with reservations required for group camping. The Great Basin is further distinguished as the largest region of endorheic drainage basins in North America.
