Things To Do


Underhill State Park is probably best known for its hiking. Four trails lead to the summit ridge of Mt. Mansfield from the park. The Sunset Ridge Trail, which is 3 miles to the summit, is the most popular. Vermont's Long Trail traverses the summit ridge and with several trails from the other side of the mountain, many loops are possible.

This mountain park contains a small campground with group camping, a log picnic shelter, built by the Civilian Conservation Corps, and a restroom facility with flush toilets and cold running water (no showers). Due to the park's hillside nature, it is not suitable for RVs or trailers. All campsites are walk-in. This off-grid park uses solar power for office functions and to operate the water system.

Underhill is within Vermont's 39,837-acre Mt. Mansfield State Forest. On the headwaters of the Brown's River, about 2,000 feet elevation, the park lies on the west slope of 4,300 foot Mt. Mansfield, the state's highest peak. The elevation and corresponding exposure to harsh climatic conditions have resulted in some relatively unusual vegetation types along the mountain's summit ridge. The low, fragile plants found in the alpine tundra near the summit are very rare in New England. They are more typical of types found on broad expanses of Arctic tundra a thousand miles farther north.

    Take a scenic drive on Route 108 through the historic Smugglers' Notch Pass. This dramatic drive from Smugglers' Notch to Stowe brings travelers through a rocky, alpine landscape with steep cliffs on either side. A great place to go for a ride or a stop for a picnic. Also, try Mt. Mansfield's auto road ($) which provides views of Stowe and beyond.

  • Camping

    Within Underhill, the campground is split. The upper camp area has 7 lean-to sites and 2 tent sites and is reserved for organized group use. This area is a 0.8 mile moderate walk uphill from the lower campground. There is a pit toilet that serves the group area. The lower camp area has 11 tent sites and 6 lean-to sites. There are cold water and flush toilets in the rest rooms, but no showers. This park is not recommended for RV or tent-trailer campers due to the steep terrain. Firewood is available for purchase. Pets are permitted.

  • Fishing
