Things to Do in Calais, Maine: St. Croix Island, Wildlife & Border Day Trips

Calais (pronounced “Callus”) sits on the St. Croix River at the Canadian border, across from St. Stephen, New Brunswick. It is a small, quiet city at the far eastern edge of Maine, and it works well as a base for Downeast Maine, the Quoddy region, and day trips into Canada. This guide covers what to see and do in and around Calais.
