Coggman Pond can be viewed from Bay Road or Ghost Hollow Road although the former provides more vantage points. As the land surrounding the pond is posted, viewing must be done from the road. The pond itself is not terribly productive, but it's worth a scan if you are birding Cogman Road/Ghost Hollow Road. 

Coggman Pond (20 acres) is a site for the Vermont LoonWatch annual survey. Birders are encouraged to volunteer as often and whenever they are able. See Join LoonWatch for details.
