Visiting Lost River Caverns Near Allentown

We love visiting caves! You get a fun geology lesson while walking a few hundred feet below ground. And the best part, you can enjoy your visit no matter what the weather is outside! We actually love visiting caves in the summer as a great way to cool off.

We’re lucky to have some caves near Philadelphia, including the Lost River Caverns. I like this one because it is perfect for younger kids. The cave is small, so the tour isn’t too long. But that doesn’t mean you won’t have fun!

What to Expect on This Pennsylvania Cave Tour

Tour Highlights

There might be puddles of water on the ground, with that in mind. It’s best to wear closed-toe shoes that won’t slip.

Some of the paths have low headways. Other paths can be a tight squeeze between the formations. Be careful not to touch any of the formations, as growth will stop.
