Great Pond is a shallow pond, averaging no more than five feet in depth. The approximately 130-acre pond and wetland complex is surrounded by woodlands.
Despite its small size, this pond is important for two rare marshbirds: Least Bittern and Common Moorhen. This cattail marsh provides excellent habitat for these secretive birds, as well as for a variety of waterfowl during migration.
Half of the shoreline is undeveloped and owned by the Sprague Corporation. There are two neighborhoods of roughly 60 single-family homes located north of the pond.
Access is maintained by both the town of Cape Elizabeth and the Cape Elizabeth Land Trust. The pond is accessible by a sandy beach that is used as a boat launch. There is also a hiking trail to the pond from Route 77.
