The Missisquoi National Wildlife Refuge was established in 1943 to provide habitat for migratory birds. It consists of 6,729 acres, mostly wetland habitats, which support a variety of migratory birds and other wildlife. The 900 acre Maquam bog is designated as a Research Natural Area and the refuge was designated as an Important Bird Area in partnership with the Audubon Society. The Refuge in partnership with other publicly owned (State of Vermont) lands has been designated a Wetland of International Importance under the Ramsar Convention. A mosaic of wetland habitats offers opportunities to see and manage more than 200 species of birds. Fall migration features 20,000-25,000 migrating ducks. Nesting bald eagles, osprey, and a great blue heron colony numbering more than 300 nests are present on the refuge.

Flat gravel bike trail or old railroad bed that follows the river. 2nd part of the trail out to the estuary was closed and overgrown. Hot midday. No loop. Out and back. There are several trails in the missisquoi valley system. This listing is misleading as it only describes one of them.

this trail is very pretty. It is a nice walk that is very flat, but scenic. there is one area that has a lot of dragonflies in the summer. good for jogging strollers and kids of any age.
