Diana's Baths, Bartlett, New Hampshire
Once the location of a sawmill operation and now a protected historical site in the White Mountain National Forest, the Diana's Baths swimming hole is best on a warm, full-moon night. Locals say it's the most romantic spot in Mt. Washington Valley: secluded, private, and perfect for skinny-dipping under the stars. By day, the cascading falls and pools, waterspouts, and granite basins are a family favorite. An easy half-mile trail leads from the parking area to Diana's Baths just past Echo Lake State Park near North Conway.
What's Nearby: A drive to the top of the park's Cathedral Ledge reveals a great view of the valley. The ledge is also a popular rock-climbing area. Take the kids on a Conway Scenic Railroad train ride or to the sandy beach at Echo Lake.
