Great Basin in July: what the park service says

July is Great Basin's comfortable season: at 6,825 feet the park service puts summer highs around 85°F and lows near 55°F. Hike early, because afternoon thunderstorms are common, and stay up late, since the park offers what it calls the best visibility of the Milky Way in the continental United States. For Lehman Caves, book a ranger-guided tour ahead and arrive 15 minutes early to check in; if you are not checked in five minutes before, you lose the ticket.
