The Red-blazed Loop trail is a family friendly trail that features views of the lake.
The state park was once the site of Thompson's town farm where elderly residents of the village spent their reflective years. Prior to that, it had been a fishing area of the Nipmuck Indians. In 1866 the town of Thompson granted the right to flow what was then Kings Pond to a higher level creating Quaddick Reservoir. The reservoir was heavily used as a source of power as well as water for processing textile materials in the plants in Killingly. In 1951, Quaddick was designated a state park after originally being developed as a Forestry recreation area.
