CASCADE CAVERNS Cascade Caverns is one of oldest tourist attractions in Boerne. It is known as a "living cave", meaning it is still growing and developing. Stalagmites and stalactites grow slowly over thousands of years with many colors from all the minerals present in the water. An under ground waterfall? They do exist and there is one here! This is a short 25 miles from Walnut Canyon Cabins. We will work with you to make sure you get reservations. AND Bat tickets for the Old Tunnel State Park Bat emergence! You will receive a pass for entry to Cascade Caverns for each person in the cabin up to 4 people. A value of up to $80.00. BOOK YOUR CABIN HERE!
