Lava Beds National Monument - California

One of the most remarkable places in the country, Lava Beds National Monument will challenge your very definition of a "cave." This incredible natural landmark in California was formed by the movement of volcanic lava over the earth’s surface a half million years ago, resulting in a rugged landscape dotted with diverse volcanic features above ground, and more than 800 caves below ground. In addition, the park is geologically outstanding because of its great variety of "textbook" volcanic formations, including fumaroles, cinder cones, spatter cones, pit craters hornitos, maars, volcanic fields, and lava tube caves. There are 25 lava tubes at this national park, and they are open to adventurers for tours and exploration. Come and revel in this glorious underworld that's 500,000 years in the making.

Montana might be known as "Big Sky Country," but there's a massive underworld in the state that commands attention, too. The Lewis and Clark Caverns are of the largest limestone caves in the northwest United States, named as such because the famous Lewis and Clark expedition camped within sight of the caverns in 1805. The caves are known for their otherworldly limestone formations formed millions of years ago, with a dazzling array of stalactites, stalagmites, and columns protruding from the cavern walls and ceiling. The 3,000-acre park features not just cave tours, but also beautiful scenery and a campground, making this an amazing destination for your next bucket-list adventure.
Wind Cave is located in the eponymous national park, near the city of Hot Springs, South Dakota. Established in 1903 by President Theodore Roosevelt, Wind Cave National Park is one of the first national parks in the country and the first-ever to protect a cave system. Boasting 33,847 acres, Wind Cave National Park houses a complex cave system that dates back millions of years, as well as a rich Native American history and abundant wildlife. Billed as the sixth-longest cave in the world (at 140 miles), Wind Cave is also considered to be the densest and is also home to approximately 95% of the world's discovered boxwork formations. Superlatives aside, Wind Cave National Park is breathtakingly beautiful; it's truly a must-visit place for all adventure-seekers.
Jewel Cave National Monument - South Dakota

Offered daily, the Scenic Tour lasts 90 minutes and gives visitors the once-in-a-lifetime opportunity to see the cave's calcite-adorned chambers up close.
Arizona's Antelope Canyon defies definition; this gorgeous canyon is unlike many others that dot our remarkable country, as it's a slot canyon with tall sandstone walls, unique natural designs, and a palette of warm, rich colors. Antelope Canyon is located on land belonging to the LeChee Chapter of the Navajo Nation in northern Arizona, and luckily for us, the Navajo Nation has been generous enough to open this sacred site to visitors who travel through with permitted guides. If you are looking for an adventure that makes you feel like you are in a different world, Antelope Canyon in Arizona deserves a top spot on your bucket list.
Carlsbad Caverns in New Mexico might just be the most beautiful place in the entire country. Located 20 miles outside of the city of Carlsbad, this extraordinary natural wonder is a limestone cave that was once part of an underwater reef in an inland sea. Put in perspective, the body of water that formed the cavern was on the earth 250 to 280 million years ago. Today, visitors can explore this otherworldly expanse on two trails: The Big Room and Natural Entrance. We're partial to the former; it's the largest single cave chamber in the United States and features stunning formations such as the fabled Sword of Damocles.
