About Allens Pond

Spanning hundreds of acres of protected beach, fields, woodlands, pond, and marsh, Allens Pond Wildlife Sanctuary was created by generous families who opted to conserve their land. Extensive trail systems offer ocean and pond views from many vantage points and afford visitors a full day of walking and birding.
