Cave in to Adventure

Lost River Caverns

Lost River Caverns

Looking for a fun, family adventure close to home?

Check out Lost River Caverns, nature’s underground wonderland in the Lehigh Valley.

Take a 30-40-minute guided, walking tour where you’ll discover five picturesque cavern chambers with an abundance of stalactites, stalagmites, and other magical crystal formations, fluorescent minerals and even a Lost River.

Outside, you’ll find an 1800-foot nature trail traversing about two acres of woodlands for hiking enthusiasts.

After your spelunking adventure, visit the on-site Gillman Museum and Gem Mill. The museum features rare fossils, unique minerals, gemstones and interesting curiosities, including a 17th century weapons collection. The Gem Mill is a functional reconstruction of a 19th century mining operation.

After you've worked up an appetite, enjoy a family picnic in the shaded Picnic Grove overlooking Silver Creek. For more information, including directions and hours of operation, visit the Lost River Canyons website.

What to bring – Wear sensible, non-slip walking shoes to avoid slipping on the wet cavern floor. Since the temperature is a constant 52 degrees underground, you’ll want to have sweaters or jackets for everyone in your expedition. Pack a picnic basket with lunch, snacks and bottled water if you plan to stay a while.

Plan accordingly – The nature trail forms a bisected loop that can be rugged and steep. Allow 15 to 20 minutes to hike the trail. The last cavern tour departs one hour before closing.

Cost Adults $12.00, Children (ages 3 – 12) $7.50
