Facility Overview

The Underhill State Park parking area is the premier western trailhead staging ground for Mount Mansfield, situated at 352 Mountain Road in Underhill, Vermont. Nestled within Mount Mansfield State Forest on the mountain\'s rugged western slope, this rustic, open-air gravel surface facility serves day-use hikers, backcountry adventurers, and seasonal campers. Because the lot is completely open to the sky, there are no structural overhead clearance barriers, providing open headroom for standard passenger vehicles, SUVs, light pickup trucks, and campervans. However, drivers operating large motorhomes, extended travel trailers, or heavy commercial vehicles should exercise extreme caution: the final 0.75-mile stretch of Mountain Road past the winter gate is narrow, unpaved, steep, and winding, making it unsuitable for oversized rigs and low-clearance sports cars.

Prime Location & Nearby Attractions

Underhill State Park sits directly at the base of Vermont\'s highest peak (4,393 ft), serving as the starting point for some of New England\'s most celebrated hiking routes. Key recreational points of interest accessible directly on foot from the parking area include:

• Sunset Ridge Trail: The park’s signature alpine route, departing steps from the lot to deliver panoramic vistas across Lake Champlain and the Adirondacks leading to Mount Mansfield\'s \'Chin\' summit.
• Laura Cowles Trail & Halfway House Trail: Direct mountain pathways starting right at the trailhead that connect to the Long Trail system.
• Cantilever Rock: A famous 40-foot sandstone protrusion located roughly 1.5 miles along the Sunset Ridge Trail.
• Underhill State Park Campground: Features walk-in lean-tos and tent sites situated immediately adjacent to the upper day-use lot.
• Underhill Center: Located approximately 4 miles west down Mountain Road, offering quaint country stores, local provisions, and relaxed rural dining.
• Smugglers\' Notch & Stowe: Accessible via a scenic 45-minute drive around the mountain range for resort amenities, dining, and winter sports.

Access, Navigation & Transit Connectivity

Vehicular access is achieved by navigating Vermont Route 15 to Underhill Flats, turning onto Pleasant Valley Road toward Underhill Center, and following Mountain Road eastward up the mountain flanks into the state park. During the official operating season (typically mid-May through mid-October), the upper park road is open, permitting vehicles to drive past the lower gate up to the ranger contact station and day-use parking stalls. When the park is closed in late autumn, winter, and mud season, the upper gate is locked, requiring hikers to utilize the limited lower winter parking lot at the end of the town-maintained road and hike the remaining road distance. There is no scheduled public transit or municipal bus line servicing this remote alpine park; private vehicle, carpool, or chartered transport is necessary.

Visitor & Driver Tips

Parking at Underhill State Park operates on a standard per-person Vermont State Park day-use entry fee (or via a valid Vermont State Parks vehicle pass). The lot regularly fills to capacity early in the morning on fair-weather summer weekends and during peak autumn foliage in September and October. Visitors are strongly advised to arrive before 8:30 AM on weekends to secure a spot and ensure safe, legal parking. Respect all \'No Parking\' signage along the narrow gravel access corridor, as Mountain Road must remain clear for emergency and ranger service vehicles at all times. Cellular connectivity is limited or nonexistent along the upper mountain road, so download trail maps and driving directions offline before heading up.
