Just across Rt 1 from the community garden in Groton, there is an entrance to a small parking lot and a sign announcing the Poquonnock River Walkway, a Groton park. Completely accessible, the well-maintained boardwalk meanders along the shore of the Poquonnock River out past the airport. Approximately 1/2 mile long, Railings, brush, variety of trees, tall grasses protect shore and woodland birds. We saw swans, ducks, gulls, a Carolina Wren, and also a variety of feeder birds, which drew our attention to the fact that this "wilderness" in fact is a narrow park with the river on one side and a neighborhood (and bird feeders) on the other. Safe for children, the elderly, and those with mobility problems. Great for an afternoon walk in any season.
