What is Robert F. Smith Cold Brook Preserve like?
66-acre wetland and upland preserve where a 2025 eco-restoration returned retired cranberry bogs to free-flowing wetlands along Cold Brook, which runs from spring-fed Grassy Pond to Saquatucket Harbor. About 2 miles of trails cross the brook on berms in three places, and a half-mile wheelchair-accessible All Persons Trail loops the bogs. Home to 280+ plant species and a 44-box bluebird trail. Named for HCT founding trustee Robert F. Smith.
