Flight
You have a few options if you're flying in. We recommend flying into Montreal International Airport (if you don't mind crossing the border), Burlington International Airport, or the Manchester-Boston Regional Airport. All options are about a two-hour drive to Newport.
Travel Note
St. Mary's Church is on top of a hill right next to downtown Newport. Once you're downtown it is very walkable with plenty of parking, lake front views, and some small shops. The reception will be in the town of Irasburg which will be about a 20 minute drive from Newport so plan accordingly!
