Beaver Brook North is part of DCR's Beaver Brook Reservation. It is located in Lexington and Waltham, Massachusetts. It was formerly the property of the old Metropolitan State Hospital. Beaver Brook North doesn't have the most challenging trail inventory but that being said, it is a surprisingly large chunk of green space nestled in between Belmont, Lexington and Waltham. It abuts other open space, Belmont's Rock Meadow which allows connection to Belmont's McLean land as well. It is also a segment of the Western Greenway.

Beaver Brook North is great if you live nearby and also if you are new to mountain biking as the trail inventory isn't very technical. It's worth a visit for variety! It does have some good hill climbs if you want to boost the challenge and tackle Mackerel Hill, but most of it is carriage paths or swoopy singletrack.

Many walkers and dog owners frequent Beaver Brook North so please be courteous and keep things friendly!
