Cavern

Longhorn Cavern State Park is one of the most unique underground experiences you can share with kids in Texas. The guided walking tour covers about a mile through a massive cave system carved by an ancient underground river, and unlike most cave tours, the path is mostly flat, dry, and well-lit - making it manageable for kids as young as 4. The cave stays a constant 68 degrees year-round, which makes it a perfect escape from Texas summer heat or a cozy winter outing. Cathedral-sized rooms open up along the route, and your guide will point out fascinating geological formations along with stories about the cave’s wild history - it served as a Confederate gunpowder factory, a Prohibition-era speakeasy, and a hideout for Sam Bass’s gang. ...

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.
