101 FUN THINGS TO DO: Spelunking in, under and around Marble Falls

Spelunking is not getting close to nature — it’s getting INSIDE nature. And at this time of year, it’s a great way to take a cool break from the summer heat.

The easiest place to go down under in the Highland Lakes is at Longhorn Cavern State Park on Park Road 4 in Burnet County. Daily guided tours feature easy walks through the caverns where outlaw Sam Bass is said to have stashed some of his stolen loot.

For more serious caving, however, check out the Wild Cave Tour at Longhorn Cavern. You’ll see parts of the cavern only a few people have visited. It’s a bit tougher than the walking tour and not recommended for those afraid of tight spaces.

The walking tours are typically offered daily while the Wild Cave Tour is on Saturdays and requires reservations. Visit the park’s website for more.

Spelunking at Colorado Bend State Park

Colorado Bend State Park outside Bend also offers a wild cave tour. To find the park, go north on U.S. 281 to Lampasas and, from the 281 and U.S. 183 intersection, take FM 580 west 24 miles to Bend and follow the signs to the park entrance. Call (325) 628-3240 ahead of time to find out when the next tour is or visit visit the TPWD website.
