In the winter, the Wheeler Peak Scenic Drive is only open to the Upper Lehman Creek Campground and Lehman Creek Trailhead. Opening dates of the higher portions of the road depend on weather. The road usually opens for the summer season starting in May, June or early July. It usually closes by late October or November. This is a fairly arid region, most precipitation received as snow or during summer thunderstorms.
Winters are cool and summers are mild.
Be prepared for changes in weather. The main park entrance is five miles west of Baker, NV, near the Nevada-Utah border. The closest major commercial airports are located in Salt Lake City, Utah and Las Vegas, Nevada. No public transportation is available to, or in, Great Basin National Park. Personal vehicles or commercial tours are necessary.
