10 Amazing Waterfalls Within Reach - WESTCAVE PRESERVE Less than an hour's drive from Austin, Tex. Take a guided hike down into a cool cave formation featuring lush, green ferns under a canopy of cypress trees. The short trail ends in an enchanting grotto where water cascades over a broken rock formation, a unique setting in the heart of the Texas Hill Country. Best time to visit: Year-round, but open to the public only on weekends.
Drive 30 miles west of Austin to Hamilton Pool to see an amazing swimming hole/cave/waterfall that was featured in the film Tree of Life. If the weather is too cold to swim, take some time to hike there instead (and stop for BBQ at Opie's on the way home).
