Hidden in Texas Hill Country-just about an hour from Austin-is an artesian spring known by locals as Jacob's Well. Whether you're diving in during one of the blazing hot days of summer or on a more mild winter afternoon, the waters that bubble up here remain a moderate 68 degrees.

According to travelandleisure.com, the jump in requires a leap off a nearby outcropping. The network of caves has been an attractive spot for daredevils, though SCUBA diving is not permitted and can be very dangerous in this narrow sliver of earth. Instead, stick to sunbathing and swimming, which is permitted between Memorial Day and Labor Day.

In the off-season, visitors can enjoy nearby hikes, and can still admire (and Instagram) the unusual swimming spot-with no fees or reservations necessary. The county is now restricting the number of visitors to Jacob's Well, so be sure to reserve a spot in advance. Your time at the swimming hole will be limited to two hours-plenty of time to take in the sights and swim to your heart's content.

There are other swimming holes in Texas for you to visit if in case you won't be able to book your trip here in advance. Like Hippie Hollow which is Lake Travis' famous "clothing optional" swimming hole. If you're looking for true aquatic freedom, Hippie Hollow is your spot says wideopencountry.com. Landa Park at Comal Springs in New Braunfels also has its Edwards Aquifer which feeds into a massive lagoon complete with lazy tubing, climbing, and even a slide carved into the side of a dam! All of which travelers who want that hype up summer experience can truly enjoy.

Other bodies of water in which travelers can enjoy less strenuous activities are also available within the vicinity like the Schumacher Crossing in Hunt, McKinney Falls in Austin, and Blanco State Park in Blanco which are all waterfalls perfect for travelers who wants to appreciate nature's beauty.
