Perched atop Mount Prospect in Lancaster, Weeks State Park offers one of northern New Hampshire’s most rewarding panoramas without demanding a grueling hike to earn it. From the historic stone fire tower at the summit, visitors look out across the Presidential Range, the Upper Connecticut River Valley, and Vermont’s Green Mountains — a 360-degree sweep that’s especially stunning during fall foliage season.

The park’s 420 acres center around the Weeks Estate, the former summer home of John Wingate Weeks, the U.S. Senator and Secretary of War who championed the Weeks Act of 1911 — the landmark legislation that created the White Mountain National Forest. The estate’s lodge now serves as a small museum documenting that history, making this park equal parts scenic destination and conservation landmark.

A network of trails winds through mixed hardwood and spruce forest to the 2,059-foot summit. The auto road to the top makes the views accessible to all ages and abilities, while the hiking trails reward those looking for a moderate woodland walk. Birding is productive here, particularly during warbler migration in late May, and the open summit meadows attract butterflies through summer.

Visit between late September and mid-October for peak foliage — the summit vantage point is one of the best leaf-peeping spots in Coös County. Summer weekends bring clear skies and long views, while fewer crowds midweek make for a quieter experience.

No entrance fee is charged, making Weeks one of the region’s best free outings.
