After breakfast, pack a lunch, hop in the car and drive about an hour to Great Basin National Park. There you can explore the mysterious Lehman Caveswith their beautiful stalagmite and stalactite formations. You’ll need to sign up for a guided tour to enter and they do sell out, so reservations are strongly recommended. After you surface, there are any number of casual or strenuoushikes in the park. Walk through the majestic BristoleconePineforests —some say these trees are the oldest living things on the planet. If you stick around the park long enough, you can also enjoy some of the best stargazingin the country.Thanks to the low humidity and minimal light pollution thousands of stars, numerous planets, star clusters, meteors, man–made satellites, the Andromeda Galaxy, and the Milky Way can be seen with the naked eye.
