Elm Brook Park offers picnic areas, baseball fields, bathrooms, public swimming, and several paved and gravel paths to explore within the facility. The park is only open on weekends, which limits access during the week. Beyond the park, a snowmobile trail—open to bikes and hikers in the summer—extends for 20 miles.
Walkers and bikers may explore the trails that pass over the flood control structure in the park and reconnect with park paths and roads. The gentle slopes, and wide, prepared trail surfaces make Elm Brook Park a great place for family biking. However, locked gates during the week at some trail access points require detours around them, which could be a barrier for some users. Additionally, trail maps and clear signage for trailheads are limited, so navigation is not always straightforward. See Trail Access Information below for more information about this Accessible Experience.
For those seeking more adventure, multi-use trails along Hopkinton Lake access two additional flood control structures east and west of the park. These trails pass through mixed forest and fields and are part of the Army Corps of Engineers Hopkinton-Everett Lakes Project. On the west side, the trail follows the Contoocook River before ending in Henniker; on the east side, it links to the Hopkinton-Everett multi-use trail system. These trails are not well-maintained and may be impassable in sections. Motorized vehicles should be anticipated, and hunters may be present outside Elm Brook Park.

It involves multiple large flood control structures and covers a drainage that includes Choate Brook and the Contoocook and Piscataqoug Rivers. Much of the land is open to hunting and fishing.
