Weeks State Park sits atop Mount Prospect (2,059 ft) in Lancaster, just 6 miles from Riverside Camping & RV Resort. The park is named for John Wingate Weeks, a Lancaster native who served as U.S. Secretary of War and authored the Weeks Act of 1911, which established the eastern national forests including the White Mountain National Forest. Today, the park offers one of the most accessible and rewarding viewpoints in northern New Hampshire.
The Fire Tower
The stone fire tower at the summit of Mt. Prospect is the park's centerpiece. Climb to the observation deck for unobstructed 360-degree views of the Presidential Range, the Kilkenny Range, the Connecticut River valley, and Vermont's Green Mountains. On clear days, visibility extends over 50 miles. The tower is one of the best viewpoints in the White Mountains region and is particularly spectacular during fall foliage season.
Trails and Access
The summit can be reached by a moderate 1.5-mile hiking trail or by driving the auto road to the top. The hiking trail gains approximately 700 feet of elevation through mixed hardwood and conifer forest, making it suitable for families and casual hikers. The auto road provides access for those who prefer to drive. Both options lead to the fire tower, the historic Weeks Estate, and picnic areas at the summit. Admission to the park is free.
Dark Sky Viewing
The summit's elevation and minimal light pollution make Weeks State Park one of the better stargazing locations in northern New Hampshire. The summit provides views above the surrounding tree canopy, reducing light interference from ground-level sources. While the park itself closes at dusk, the area around Weeks State Park and nearby Riverside both fall within a Bortle Scale 3-4 zone, offering exceptional conditions for observing the Milky Way, meteor showers, and planetary alignments.
The Weeks Estate
The historic Weeks Estate at the summit houses a small museum and exhibit space documenting the history of the Weeks Act and the conservation of the White Mountains. The building itself, constructed in 1912, offers a glimpse into early 20th-century architecture and the era of federal conservation leadership. Admission to the park and museum is free.
