Forbidden Caverns

Looking for a unique attraction while visiting the Smoky Mountains of East Tennessee?
Forbidden Caverns is a cave under the Great Smoky Mountains where natural caverns are large and amazing! Tour guides take you on an fascinating journey through the cave and tell you the history and the science behind the formations. Souvenirs are available to remember this astounding feature under the mountains. 

History of the Caverns

The Forbidden Caverns were explored by the eastern woodland native Americans and used as a shelter in the winter. With its continual flow of water, it was the perfect place to wait out winter. Scientists believe this water is from an underground lake under English Mountain, which is known for its spring water.

In the early 1900s, the cave was used as a place to make moonshine. The cave was the perfect place to hide what moonshiners were doing. There’s a replica of a homemade moonshine still on the tour.

In 1964, a group of businessmen opened Forbidden Caverns to the public, so people could learn about the history of the cave and the formations inside. The official opening was in 1967 after years of development to make it safe for people to visit.

All types of formations can be seen in the cavern. There is cave onyx, grottos, and flowstone, plus stalagmites and stalactites. Draperies flow down from the ceiling. Some draperies have water flowing down their surface. Don’t be surprised if you see bats flying around the cave!

Gregory’s Cave

Gregory’s Cave is an underground cave located in Cades Cove. Drive along the Loop until you reach the John Oliver Cabin. There’s a dirt road with metal bars blocking it on the right. Hike along this road until you see a small picnic area. Just past the picnic area are a few trees with boxes on them. The cave entrance is just past the trees. Gregory’s Cave is the only cave in the national park that was used commercially. The family that owned the property opened it to the public in 1925 and held tours through the cave.


Bull Cave

Bull Cave is the deepest cave in the southeastern United States at 924 feet. It is also located in Cades Cove, so you can find both caves in one day. To find the entrance to Bull Cave, start hiking along Rich Mountain Road. Near the beginning of the trailhead, you will notice a side trail, which will lead you to Bull Cave. The cavern got its name because this road was used to transport cattle, and apparently a bull fell in the cave.


Cave on Goshen Prong Trail

There is a Smoky Mountain cave off of Goshen Prong Trail near Clingmans Dome in the national park. The trailhead is located about 2.4 miles off the Appalachian Trail from the Clingmans Dome parking lot. This difficult trail starts out descending down the mountain, and is slick and rocky. The cave isn’t too far down the trail, and it sits on the right, about 40 feet into the rock formation. Again, the National Park Service prohibits visitors from exploring caves due to safety concerns for people and the safety of endangered bat species in the area.


Rainbow Falls Cave

schoolhouse gap trail

Most people have heard of Rainbow Falls, or hiked to this waterfall, but we aren’t talking about that waterfall! Rainbow Falls Cave is a small waterfall that pours into an underground cave along Schoolhouse Gap Trail. About 1 mile into the hike, there is a junction in the trail. You’ll see a sign that reads “Schoolhouse Gap Trail” and “Turkeypen Ridge Trail.” Past these signs, there is an unmarked trail on the left that will lead you to White Oak Sinks. Take this trail for about 1 mile, and then you will come up on another junction. Take a right at this fork to reach Rainbow Falls Cave. The waterfall is 40 feet tall, and you will be impressed since the water pours into the cave instead of a pool of water!


Blowhole Cave

Blowhole Cave is another hidden Smoky Mountain cave you’ll want to try to find while you’re exploring. This cave is also accessible along the Schoolhouse Gap Trail. Instead of taking a right at the fork to go to Rainbow Falls Cave, take a left to go to Blowhole Cave. You’ll spot the entrance to the cave because it is blocked off by metal bars. The cave exterior is impressive by its sheer size and the fact that it is covered in moss. Blowhole Cave is home to the largest hibernating colony of Indiana bats in Tennessee, which is part of the reason why caves in the area are not accessible to visitors.

The Lost Sea Adventure

Your Lost Sea Adventure begins with a guided tour of the caverns. This involves a ¾ mile round-trip walk on wide sloping pathways. While touring the caverns and underground lake the guides will tell of the cavern’s exciting and colorful history. They will also explain the fascinating geological development of the immense cavern rooms and rare formations. At the bottom of the cave you will take a boat ride on The Lost Sea, America’s Largest Underground Lake.

The Lost Sea Adventure is open every day of the year for tours (except Thanksgiving and Christmas Day). The tour takes approximately 1 hour and 15 minutes. Either before or after your tour you might want to visit the Lost Sea Village where we have several shops.  Or take a walk on our self-guided Nature Trail.
