As of today, we are done with winter. Done. Time to usher in spring and flowers and bunnies and thoughts of heading down to the ol' swimmin' hole in summer.

If you don't have a local swimmin' hole (spelling it "swimming hole" just seems wrong), consider a trip to Dripping Springs on the western outskirts of Austin, Texas. There you'll find a marvelous water-filled grotto called Hamilton Pool. Fed by a waterfall and protected by overhanging limestone, it's a gorgeous place to take a dip.

Visit Atlas Obscura for more on Hamilton Pool.

Swim with a view at these awe-inspiring natural pools:

• The world's highest and most dangerous infinity pool lies at the edge of Victoria Falls
• A gaping hole in the surface of the lush green island exposes a secret beach
• The azure waters of Cenote Xkeken were thought to lead to the Mayan underworld
