D.A.R. State Forest is a 5 mile loop trail located near Williamsburg, MA. The trail is primarily used for hiking and mountain biking.
Great spot! Be careful if your not familiar with the aria tho- there are several private trails and town roads connecting into the state forest and no signs that tell you when your leaving only entering. There's a great trail going to chapel falls reservation that's a great place to swim or rock climb if you want to make a full day of the aria- the dar itself is not all that big.
I use these trails when I want to get a quick hike in for exercise. I usually go up to the firetower via the Black Bear trail then take the Long Trail along the lake. It's about 4 miles and I often go around twice
The DAR has many miles of trails beyond the five miler mentioned. some of these are:Black Bear, Porcupine, Long trail, Bobcat,NEMBA ,etc.. Many of these trails are mtb oriented but are used by hikers as well. The difficulty ranges from beginner/intermediate to advanced with many rock features and climbs. I have pieced rides from 12 to 20 miles long here and not done all the trails available. There is a fire tower that has great views of western mass and Greylock mtn. There are camp sites, two beaches two lakes and a handicapped accessible trail as well. The D.A.R. is a great outdoor resource in w. mass. The maps available at the ranger stations are fairly accurate and include all the trails. The park is open year round with xcountry skiing and snomobile activities in the winter
