The Lodge at Woodloch, which opened June 26 in Hawley, Pa., on 75 wooded acres with a private lake, is the first new luxury destination spa in the region since Canyon Ranch came to Lenox, Mass., in 1989. Rates start at $575 per night (thelodgeatwoodloch.com). The other spa is an addition to the Mayflower Inn, a super-luxe hotel in Washington, Conn. A five-night spa stay starts at $6,700 per person (mayflowerinn.com). This July 4 weekend will be wild indeed at the opening of the Wild Center/Natural History Museum of the Adirondacks in Tupper Lake, N.Y. The $25 million center features a river, populated by live animals such as otters and turtles, that runs through its 12,000-square-foot main hall. The July 4 WildFest will feature an outdoor pond stocking, tree plantings, and an interactive children's theater (wildcenter.org).
