Every local knows it for its swimming hole, but the only state park in Austin’s borders is a hiker's dream. The three-trail system lets you choose your own adventure. History buffs will enjoy taking the Homestead Trail, which takes you to the ruins of namesake Thomas McKinney’s stone house and gristmill. Families with very young children should opt for the stroller-friendly Onion Creek Hike and Bike Trail, while introverts can travel along the less-popular Rock Shelter Trail, shaded by limestone cliffs.
