Only 300 miles north of Las Vegas, Great Basin feels like its much farther from the neon lights and plastic shopping centers of Sin City. Known for its ancient bristlecone pines and marble caves at the base of Wheeler Peak, the Nevada park has five campsites scattered throughout with toilets, picnic tables, tent pads, and grills. 

Don't Miss: The glacier-lined summit of 13,063-foot Wheeler Peak is worth the effort. You can reach the trailhead from the 12-mile Wheeler Peak Scenic Drive, which begins at the park's eastern boundary and crosses through groves of aspen, Englemann spruce and limber pine trees.
