Grills Sanctuary, Hopkinton

Hopkinton Land Trust

Hunting is not allowed here but it is permitted on nearby land. During hunting season everyone using the trails here should wear blaze orange. Remember, hunting season includes much of the late fall, winter and spring. More details.

In Rhode Island the primary hunting seasons typically run from the second Saturday in September to the last day of February and from the third Saturday in April to the last day in May, however this can vary from year to year and depends on what game is being hunted. During hunting season you should wear at least 200 square inches (a hat OR a vest) of blaze orange. During shotgun deer season, which is typically in December, you should wear at least 500 square inches of blaze orange (a hat AND a vest). For more information see the RI DEM website.

The trailhead opens to a mowed field and then the trail negotiates cornfields before entering the woods. Most of the three miles of paths east of Tomaquag Brook, including the peninsula between Tomaquag Brook and the Pawcatuck River, are along old cart paths and are relatively flat. A nice stone bridge crosses Wine Bottle Brook, a tributary to Tomaquag Brook. There is an Atlantic White Cedar swamp in this low crossing area with hardwoods and pines predominating along most of the trails. The Tomaquag Brook Bridge opened November 2013 and completes the link between the Chase Hill Road and Bowling Lane Trailheads. The one mile of trail west of Tomaquag Brook and linking up to Polly Coon Bridge over the Pawcatuck River crosses a more varied wooded terrain with numerous large high rock overlooks interspersed with wooded swamps. The historic Polly Coon Bridge provided a route to move granite across the river to the rail siding in Bradford. Floods destroyed the bridge; it was elevated but was lost in another flood. The new pedestrian bridge uses the old stone abutments and will provide access to five miles of trails in the Westerly Land Trust's Grills Preserve and to their trailhead at the end of Bowling Lane.
