Great Brook is very popular since it is such a great family and beginner area. Because it is such a popular family area, it's not a great idea for advanced riders to come to Great Brook to do their serious weekend pounding. It's wise for fast riders to avoid this park on nice summer weekends. It certainly is a good idea to avoid riding hard on the main trails. The main trails are frequented by family groups of four of five people, both hikers and bikers, including young kids, often on little bikes. Some of the more out-of-the-way single-tracks offer more challenge without this risk over running over slower bikers.
From I495, take Rt 225 East crossing Rt 27. Take left on Curve St. and follow Curve St. north to North St. Take North St. to clearly marked park entrance.<br /><br />From Rt 128 (I95) take Rt 225 West. Make a right onto Lowell Rd. in the center of Carlisle. Follow Lowell Rd and make a right on North Rd. The main parking is at the duck pond and farm. If this lot is crowded, you should park at the barn and XC ski center. For bikers, its only like a minute from this lot to the duck pond. For picnicers, it's quite a hike with a bunch of stuff. <br /><br />
