Wimberley Blue Hole Regional Park
There are two different Blue Holes in the Austin area, and this one in Wimberley is arguably the better known of the pair. This natural, spring-fed swimming hole is flanked on both sides by towering cypress trees, and you can find your way into the crystal-clear water via one of the many rope swings dangling from their branches. When you’re done swimming, sprawl out on the grass or post up at one of the limestone picnic tables, available to reserve ahead of time. It’s also not far from Jacob’s Well, so you could easily make a day of it by hitting both.
Know before you go: Reservations are required for the swimming area of the park—$12 for adults from 9 am to 1 pm or 2 pm to 6 pm. The rest of the park is free, which includes a playscape and four miles of hiking trails.
