Planning to go camping out with friends or family this weekend? If you're looking for ways to relax in the great outdoors, the first thing you need to think of is where to go. Head out to these camping sites in the US and sleep among the starry night sky. 

Joshua Tree National Park, California. Take the challenge of camping out in the desert ruggedness of Joshua Tree National Park. There are almost 400 campsites on nine campgrounds where you can go backpacking, pitch your tent, or camp with RVs. During the night you can either gaze the stars or look out for night wildlife with Rangers. They also have evening programs that let you know all about Cahuilla Indians. At day time, test your photography skills and take snaps of the Joshua Tree and other cool rock formations in the site. You can hike and go horseback as well

Crater Lake National Park, Oregon. If you want to get close to a volcano, then here's your chance! Crater Lake has two campgrounds, and they're only open during summer. The Mazama Campground is open for those who wanted to pitch a tent or camp with RVs, and the Lost Creek Campground is a tent-only site. Activities range from hiking, skiing, boat tours or finding the Phantom Ship nearby!

Polihale State Park, Hawai'i. If you want to go camping with fewer people around, you can go to the Polihale State Park and have the place to yourself! You can enjoy the beach with sand dunes reaching about 100 ft tall. Activities in the state park are peaceful as you can swim (Queens Pond), stargaze and fish all day long. If you want to take a break from the busy city life, this is the perfect place to escape to.

Treehouse Point. If camping on the grounds is not for you, then you can sleep in a tree house. This is an excellent bed and breakfast cabin where you can also have morning meditation and yoga. You can fish and hike your way in the vicinity as well. To have a night in your dream tree house, you have to book first, and you have to do it fast because it's almost always booked!

Carlsbad Caverns National Park, New Mexico. If you want mysticism and folklore weaved together in your next camping trip, the Carlsbad Caverns should be on your list. Join their evening programs and get to know the local history about the prehistoric and historic American Indian groups. You shouldn't also miss exploring the Carlsbad cave. You can either opt for a tour or just guide yourself down there. Try visiting the Spider Cave, Hall of the White Giant and Slaughter Canyon Cave too.

You can find loads of information on the internet on where else to go camping to. The US never lacks any of these spectacular sites to visit.
