Thousands of migrating ducks, geese, and sandhill cranes stop here in spring as they head north to nesting grounds, and in late summer as they head south before the cold hits. It's amazing to watch them gather in huge flocks, with constant takeoffs and landings, yet no bird ever running into another. This is also a great place to view songbirds and moose. Five miles of nature trails, open year-round, lead through fields, forest, and wetlands. Don't miss the daily one- to two-hour naturalist walks. Now on the National Register of Historic Places, Creamer's Dairy was the northernmost dairy in North America from 1910 to 1966. The farmhouse is an interpretive center and gift shop open daily from 9:30 am to 5 pm between mid-May and mid-September, and Saturday from noon to 4 the rest of the year.
