Lost River Caverns....A Hidden Gem!

Best little Cavern in the area ! Can't miss it in the town of Hellertown. Just look for the big Yellow sign and follow the arrows . Nice little park across the road with picnic tables. Lots of interesting collections inside the building . Fun for kids and adults. Cavern tends to have wet walks so be careful . Do not recommend flip flops. Sneakers and shoes more practical. Guides are great with all the history of the Caverns. It's about a half hour tour. Lightweight jacket should be do. Do not touch the formations in the Cavern. Camera's are a must. The gift shop is amazing. I love the gift shop here. This my forth time in this cavern.

A Great Treasure

Tour guide was informative and funny, the collection of local and foreign artifacts was super cool, the cave was small but rich with history and visuals of slow time passing. Grateful that the family maintains and shares this place with the public. Great little adventure!

The Grand Kids Loved It!

WOW we took our 6 and 7 year old grand kids there they were amazed. Good place to bring kids to get an understanding of caverns and what's below the ground. They could not believe we went 150 feet under ground. I'm sure it will make back to school list as to what did you do this summer.

Interesting Adventure

Had a great time at the Lost River Caverns . Walked through the cave of flow stone and enjoyed the beautiful cave formations. The guide was very nice and knowledgeable. Enjoyed the small museum of the cave and it’s history as well as the different mineral rocks. Nice gift shop. All staff was friendly. Enjoyed this tour.

Excellent!

I was more than pleased with this cave tour. Partly because of the many stalactites and stalagmites. Other caves I’ve been in did not have as many. And since water was continually dripping, I knew they were growing. No one would call this a huge cave, but it was big enough to get the cave experience. 116 feet below the surface, the walk was not difficult. The waiting room/gift shop was an unusual experience in itself.
