For a summer cool-down

When to go: June and July

Family vacations in New Braunfels, an hour outside of both San Antonio and Austin, are all about keeping cool: The Comal River and the Guadalupe River flow right past the town at a pace that’s perfect for a day-long inner tube float. (You can also take a guided kayak or SUP board trip with Paddle TX.) If you’re looking for something a little more controlled, there’s the always-a-kid-fave Schlitterbahn Waterpark.

Once you dry off, though, you've got a lot more exploring to do, starting at the McKenna Children’s Museum. For tots and non-swimmers, it’s all aboard the Landa Park Train to gape at the springs that fill Landa Lake and its natural swimming pool. Beyond New Braunfels, the region overflows with kid-friendly attractions, from feeding the animals at the San Antonio Zoo to picnicking in the rolling landscape of Texas Hill Country, making a road trip an easiest way to explore.
