Bordering both Connecticut and Rhode Island, this popular 5,907-acre state forest offers a variety of recreational opportunities. Visitors can enjoy swimming, boating and fishing at Wallum Lake and hiking, horseback riding, cross-country skiing and snowmobiling onmiles of woodland trails. Facilities include two pavilions, boat ramp, swimming beach, picnic area and restrooms. The Midstate Trail, a long-distance hiking trail that extends through central Massachusetts to Mt. Watatic in the north, runs through the forest. Douglas State Forest also includes a rare example of Atlantic White Ceder swampland. A 5-acre portion of this swamp is designated as a Massachusetts Wildland. It is accessible to the public via a boardwalk trail.
We ride our horses there often and know most of the trails. Avoid midstate trails if horseback riding as it's the rockiest. Recommend boots for barefoot horses. We usually ride 6-7 mi from Wallis St or South St parking areas. Deer fly season is when to skip it.
