Enfield Falls, Robert H. Treman State Park, New York
As this New York college town's popular green T-shirts proclaim, "Ithaca is Gorges." No doubt the landscape is stunning, but it also creates a picture-perfect backdrop for swimming holes. There are about 150 waterfalls within 10 miles of downtown, and Robert H. Treman State Park's Enfield Falls are a favorite among locals and undergrads. You can swim up and sit under a billowy curtain of water or soar from the cliffside diving board. Relax on a grassy patch or hike park trails to see 12 waterfalls, including the 115-foot Lucifer Falls.
What's Nearby: The parking pass ($7 per carload) is valid all day at three Ithaca state parks: Treman, Buttermilk Falls (with waterfall swimming and gorge hiking), and Taughannock Falls (three stories taller than Niagara). There are more than 100 wineries in the Finger Lakes region. For food lovers Ithaca boasts more restaurants per capita than New York City.
