Tucked away in this 400-acre park in the southwest corner of the Granite State are ponds, bogs and a forest that extends to the shore of undeveloped Otter Lake. The park offers opportunities to swim, fish, walk, canoe, camp and picnic in a variety of settings. Walking paths lead to ponds and other points of interest in the park.

Greenfield State Park is located in the beautiful and rustic Monadnock Region of New Hampshire. Mount Monadnock, featured by some of New England’s most famous writers like Ralph Waldo Emerson and Henry David Thoreau, is just 20 miles away from Greenfield State Park. The mountain, standing at 3,165 feet above sea level, is surrounded by thousands of acres of protected highlands and is one of the area’s favorite hiking destinations.

Located in the southwest corner of New Hampshire, the 400-acre Greenfield State Park is a recreational hotspot all year long. The park’s main facilities operate on a seasonal schedule, but the park’s gates open during any season so visitors can participate in a variety of off-season activities like snowmobiling and snowshoeing.

Inside the park, visitors will enjoy beautiful camping spaces surrounded by lakes, ponds, and bogs that sit nestled in the dense forest. Campers have many opportunities to entertain the entire family with activities such as swimming, fishing, hiking, kayaking, and picnicking. The park store, located next to the lake, functions as a gift shop and small grocery and sells souvenirs and refreshments, and makes camping even more comfortable knowing there are comforts of home close by.

Swimming, fishing, as well as hiking at nearby Mount Monadnock, are favorite activities of campers at Greenfield State Park and a 900-foot beach for campers only, canoe and kayak rentals, a camp store, a dump station, and showers are available.

Pets: Pets are permitted in designated areas such as campsites. Pets must be leashed and supervised at all times and are not permitted on the beaches.

Seasonal activities in Greenfield State Park



Spend the day exploring the park on foot. Venture from the camping area out to the hiking loop, or take one of the trails to visit Beaver Pond, Mud Pond, Hogback Pond, or Spruce Swamp. Almost all of the trails access the park’s road or some of the park’s main facilities at some point along the route. Restrooms, picnic areas, and trash cans are also located conveniently near many of the trails. If you bring your pet, please keep it leashed and away from all public beach areas. Pick up park map for more detailed trail information.

Canoe and Kayak

Greenfield State Park’s small campground store rents boats and kayaks to park guests. Park patrons may rent boats hourly, by the half day, full day, or even weekly. Please bring a driver’s license to rent boats. Life vests and oars and paddles are included in the cost of the rental. Boaters can access the water by using the boat launch on Otter Lake. There is a parking area, a picnic beach, restrooms, a playground, and a camp store located near the boat launch.


Spend the day fishing on Otter Lake, one of the bigger bodies of water in Greenfield State Park. The small, 135-acre lake has both shoreline fishing and boat fishing. If you bring a boat, be aware that Otter Lake requires that motorized boats stay at trolling speed or lower. The park offers limited trailer parking near the boat ramp, and the boat ramp is considered narrow. Fish for yellow perch, smallmouth bass, largemouth bass, bluegill, chain pickerel, and brown bullhead. For licensing information, contact New Hampshire Fish and Game.


Discover the Power of Parks

Connecting people with New Hampshire’s natural habitats is one of the main goals of the New Hampshire State Parks system and the Student Conservation Association. Discover the Power of Parks puts together programs during the summer and fall that educate and entertain guests on topics relating to the state’s natural resources and cultural history. Program participants who complete five different park programs can earn a complimentary patch to recognize their accomplishments.


During the off season, the park remains open for winter recreation. If you don’t have snowshoes, rent your gear at any of the local outfitters, and bring everything with you to the park for a day out on the trails. During the winter, there may be limited staff on duty, so always be aware of weather and other advisories, and consider planning your activities with another person. See the park from a different perspective: a wintery perspective!


New Hampshire is one of the best states for snowmobiling. Whether you own a snowmobile or want to rent one for the day, you will find trails in and around the park that will give you a day of snow-filled adventure! To ride inside of the park’s boundaries, park your vehicles and trailers near the park headquarters. If you prefer to ride outside of the Greenfield State Park boundaries, park your trailer at Oak Park, which is located across the street from Greenfield State Park. Always check weather conditions and park operations before snowmobiling, as certain conditions may impact trail usage or park hours.
