Button Bay, a 253-acre park, is located on a bluff in Ferrisburgh along the 130-mile long Lake Champlain. Historically, the area has been visited by such notables as Samuel De Champlain (1609), Ethan Allen (1776), Ben Franklin (1776), and Benedict Arnold (1777). What once operated as a farm, opened as a state park in 1964. The park is so named for the button-like concretions formed by clay deposits found along the shoreline.

The camping area is generally an open, grassy area overlooking Lake Champlain and the Adirondack Mountains to the west. There are 73 sites including 13 lean-tos and 2 cabins. Flush toilets, hot showers ($), picnic areas and a dump station are provided. The park has a play area and a swimming pool with lifeguards. Boating (canoe, kayak, and rowboat) rentals are available, as well as fishing and sailing which are popular on Lake Champlain. You can explore Button Point Natural Area, a small mature hardwood forest, hike the trail, and visit the Nature Center.
