Great Basin in June: what the park service says
June at Great Basin can mean hot valley days while snow still covers the higher elevations, the park notes. Expect mid-70s°F afternoons at the Lehman Caves Visitor Center and about seven thunderstorms in the month. On the Wheeler Peak Scenic Drive, vehicles over 24 feet are not allowed beyond Upper Lehman Creek Campground because of sharp curves and steep grades. After dark, the park says, stargazers get what it calls the best visibility of the Milky Way in the continental United States.
