Allis State Park, State park and National Historic Place in Brookfield, Vermont, US.

Allis State Park covers 625 acres (253 ha) of uplands in the White River watershed in western Brookfield, Vermont. Its main feature is the summit of Bear Hill, reached by a park road that climbs west, bends south, passes an entrance gate and then splits: right to the campground loop, left to the day-use area with picnic pavilion and fire lookout tower.

Wallace S. Allis donated his Bear Mountain Farm to Vermont in 1928, creating the second state park in Vermont's history. The Civilian Conservation Corps later developed the grounds during the 1930s.

The Civilian Conservation Corps built the park's access road, camping loop and picnic pavilion in the 1930s, and the facilities were listed on the National Register of Historic Places in 2002. The picnic pavilion, at the centre of the day-use area, has handicap-accessible restrooms.

The grounds offer 26 camping spots with 18 tent sites and 8 lean-to shelters, with restrooms and water sources distributed throughout. Access comes by way of one of Vermont's few maintained gravel roads.

The fire lookout tower stands at the centre of the picnic area and gives 360-degree views of the surrounding Vermont mountains. The park road climbing to it branches off Bear Hill Road/Vermont Route 65, one of the last Vermont state highways still kept as a gravel road.
