Hippie Hollow, located in Austin on Lake Travis, is more than just a place to get naked. It's a clothing-optional park — the only one in Texas. Nudity is not allowed in the parking lot, but once you're past the tree line, you're free to strip down and have some fun along the shores of the lake. Wide, flat rocks make great spots for sunbathing, but watch out for slippery rocks that might be below the water's surface, and keep in mind that lifeguards are not on duty.
About 85,000 people visit Hippie Hollow each year, including those who come for the annual Big Nude Day event. Hill Country Nudists hosts the celebration, which mostly attracts visitors in the 50-plus age group. The park, however, is open to anyone 18 and older.
One note: While nudity is perfectly acceptable at Hippie Hollow, lewd behavior is not tolerated, and those who engage in it will be prosecuted.
