Mount Wachusett Mountain House and Pine Hill Loop Hiking Guide
At 2,006 feet, Mount Wachusett is the highest point in Massachusetts east of the Connecticut River, a lone glaciated summit rising over the farms and forests of Princeton. A road goes to the top in summer and fall, but the climb from the visitor center is the reason to come. This loop goes up the rocky Mountain House Trail and comes down the stone steps of Pine Hill Trail.
Permit: DCR charges a daily parking fee at Wachusett Mountain State Reservation from May 23 to October 26 (2026 season): $5 for vehicles with Massachusetts plates, $20 for out-of-state plates. Perimeter lots on roads outside the park are free.
Up Mountain House, Down Pine Hill
From the visitor center lot, head south on the Bicentennial Trail, which can be muddy after rain, to the junction with the Mountain House Trail. That is where the work begins: the climb to the summit is steep and rocky, with boulders to step up and over. The return on the Pine Hill Trail drops on a long run of stone steps straight back toward the parking lot. AllTrails lists the loop at 2.2 miles with about 810 feet of gain; budget 90 minutes to two hours.
The Shorter DCR Route
DCR's own signature hike here is simpler: take the Bicentennial Trail to the Pine Hill Trail and climb straight to the summit, then return the same way. The agency lists that out-and-back at 1.4 miles, rates it moderately strenuous, and suggests an hour to an hour and a half. Choose it if you want the quickest way up; choose the loop if you would rather not descend the same steps you climbed.
Parking Fee and the Summit Road
From May 23 to October 26 this year, DCR charges a daily parking fee that also covers the summit road: a Massachusetts-registered car pays $5, any other plate pays $20, and the plate alone decides which rate applies. The visitor center at 345 Mountain Road has only 28 spaces, and DCR warns you may be sent to another trailhead when it fills. Perimeter lots on roads outside the park are free. The summit road is open from Memorial Day weekend to the last weekend of October, 9 a.m. to sunset, which means the summit is busy with people who drove up on fair-weather weekends.
Old Trees and Old Stories
Below the summit, a band of old-growth forest clings to the rock ledges, with trees estimated at 150 to 370 years old; it is the largest known old-growth stand east of the Connecticut River in the state. Henry David Thoreau wrote about his trip here in A Walk to Wachusett. The reservation covers about 3,000 acres and 17 miles of trail, so the loop is just a sample.
Dogs, Hunting and Hazards
Dogs are allowed; DCR rules require a leash no longer than 10 feet and proof of rabies vaccination. Hunting is a listed activity at the reservation, so wear something bright in the fall. Poison ivy grows along the trail edges, which is a good argument for long pants. In winter the rocky upper section of Mountain House can ice over, so bring traction once the cold sets in.
