Jacob's Well Natural Area

A crystal-clear artesian spring that wells up from a deep underwater cave system creating one of the most pristine swimming holes in Texas. The water is a constant 68 degrees and so clear you can see straight to the bottom. Swimming requires reservations and is limited to protect the spring. Kids who are strong swimmers will never forget the experience of floating over the well opening and peering into the blue depths below.

Longhorn Cavern State Park

A massive cave system formed by an ancient underground river with cathedral-sized rooms that kids find absolutely thrilling to explore. The guided walking tour covers about a mile through well-lit passages with fascinating geological formations. Unlike most cave tours the path is mostly flat and dry. The CCC-built stone structures above ground are impressive in their own right and the hilltop views of the Hill Country are worth the drive alone.

Natural Bridge Caverns

The largest commercial cavern in Texas with massive formations illuminated by dramatic lighting on guided tours that descend 180 feet underground. Above ground a six-story ropes course and zip rails give older kids an adrenaline rush and the AMAZEn Ranch Roundup outdoor maze is a hit with younger children. The gem mining and panning activity keeps kids busy for a surprisingly long time.
