Who knew central PA could look like this? Penn’s Cave is just 30 minute from State College, Pennsylvania and 3 hours from both Pittsburgh and Philadelphia. It’s is the only all water cavern in the USA so visitors explore the cave entirely by boat. You’ll float past dramatic formations on top of bright blue water. The tour is out and back and lasts about 1 hour. Above ground, the fun can continue at their wildlife park where there’s bison, wolves, elk and more. Add Penns Cave to your bucket list
