Diamond Hill Swamp, Hopkinton

Hopkinton Land Trust

Also known as UBS Diamond Hill

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.

This property is located along the Hopkinton Land Trust north-south Tomaquag Valley Greenway. It connects the Grills Wildlife Sanctuary, to the south, to the Pelloni Preserve, to the north. Previously walkers had to use the roads to walk between these two properties.

The Tomaquag Brook wooded flood plain is the dominant property feature with mixed hardwood uplands along Tomaquag Trail. This is a rudimentary blazed trail without final clearing, signs or all-season stream crossings.

Formerly, visitors canoed and fished Tomaquag Brook from Old Swim Hole south to the Pawcatuck River, when farmers cleared and dairied much of the area along the brook 50 years ago. Fly fishermen considered it an excellent native trout fishery when the farmers kept the stream banks cleared.

The adjacent campground is collaborating with the Hopkinton Land Trust to develop and maintain the trail system for public use. Please respect the boundary with this private campground and leash your dogs on this property.

As of early 2014 obvious trailheads have not been cleared, nor have trailhead signs been installed.
