Hiding underneath Nevada is a whole other world that's definitely worth exploring. Before Great Basin was even considered a national park, a place called Lehman Caves was attracting visitors from all over the country. The caves are currently considered a part of Great Basin National Park and the caves can only be entered by taking a guided tour. You'll definitely want to experience the incredible wonders that this cave has to offer. This impressive cave system even contains the deepest cave in all of Nevada. Exploring Lehman Caves is a one-of-a-kind adventure that you simply can't pass up.

Great Basin National Park is the jumping off point for a variety of adventures. With so much to do and see, the park is a massive playground for outdoor lovers. However, one of the most exciting areas of the park can actually be found beneath the surface of it.

The massive Lehman Caves were discovered back in the 1880s, and they've been attracting thousands of visitors every year ever since. Once you're inside, you'll realize why this cave has held up as one of the most unique and awe-inspiring caverns in the country.

The caves can only be accessed by taking a guided tour. You'll have your choice between a 60-minute tour and a 90-minute tour, but you'll probably find yourself wanting to spend hours down in these magnificent caves.

As soon as you walk into the cave, you'll be in total shock of just how massive this place is. All in all, the cave contains two miles of passageways. It's considered the longest cave in the state and it definitely shows.

On the tour you'll be guided through all of the cave's different "rooms". The Talus Room is considered the biggest, at 21,511 square feet. It's also considered the tallest room at 113 feet from floor to ceiling.

As you stroll through the cavern, you'll be in awe at the variety of formations surrounding you. Stalagmites, stalactites, and helictites reach down from the ceiling and crop up from the floors. You'll feel as if you've been transported to a different planet.

It's hard to believe the crazy formations in the cave are the product of millions of years of erosion and movement. The cave's environment is active, meaning that it is still changing. Who knows, it may look a little different the next time you visit this place!

Unfortunately, the cave underwent significant mistreatment when it was first discovered. People were allowed to break off small stalactites during the cave's early tours and graffiti lines some of the walls. If you decide the tour, be sure to do your part in preserving this precious ecosystem.

Guided tours are offered year-round, except for on major holidays. People are advised to book well in advance since tours book up fast. Definitely make a reservation several weeks in advance in order to ensure your spot. This place is a truly incredible wonder that all Nevadans should witness.

Ticket prices vary depending on the tour. For a 60-minute tour they are $9 for adults and $5 for children. For a 90-minute tour they are $11 for adults and $6 for children. For more information about tours, you can visit their website here.
