About the Park
Otter Brook Lake is a 458-acre US Army Corps of Engineers property featuring a 90-acre lake, trails through old fields, wetlands, and shrub areas. Dogs are permitted but must remain on leash, with activities including walking, picnicking, wildlife viewing, and winter snowshoeing. The recreation area is currently walk-in only with no restrooms or shelter reservations.
infoWhat to Know Before You Go
Walking trails are available, so you and your dog can enjoy a walk beyond just the off-leash area. Trails are a great option for dogs who enjoy sniffing and exploring at their own pace.
Best of all, Otter Brook Lake is completely free to visit — no membership or daily fees required.
