        Beaver Brook is a 2,000-acre parcel of land with over 35 miles of trails. The Beaver Brook Association was started in 1964 with a small 12-acre parcel of land. The association now owns land in Hollis, Brookline and Milford. Beaver Brook is the true multi-use trail system. There are trails for biking, hiking, skiing, and equestrians. The trails are all very well marked and it is very important that you obey the signs that indicate the use of the trails. All of the trails are open to hiking and skiing, but there are many trails where biking is not allowed. The local mountain biking community has worked very hard to keep these trails open so please respect the signs and use only the designated trails for biking. Expect to find about 12 miles of really good riding at Beaver Brook.

        The trails vary from rocky single track to wide fast double track. Beaver Brook offers some nice climbs and racing descents as it travel through forests and along large wetlands. The terrain is not overly technical, but there are some good spots to stop and play. Beaver Brook is a great place for an easy roll, after work ride, or a weekend journey. The maps on this page only show a few main loops that allow bikes. For the other trails, check out the maps at the kiosk at the parking lot.
