Great Basin National Park

From the 13,063-foot summit of Wheeler Peak, to the sage-covered foothills, Great Basin National Park showcases the stunning diversity of the larger Great Basin ecoregion. It is among the least-visited national parks in the lower 48 states. Visitors can experience the solitude of the wilderness, walk among ancient bristlecone pine groves, bask in the darkest of night skies, and explore mysterious subterranean passages in Lehman Caves.
