All year! Unlike other Maine coastal towns, Damariscotta is active year round as the primary service center for the surrounding region and Lincoln County. There are very few shops and dining establishments that are seasonal. Memorial Day through Columbus Day (May-October) is the town's traditional tourist season. Weekends are especially busy during this time period. Mid week is a great time visit during the Summer and early Fall. It is always best to call ahead and confirm a business' hours any time of year.
There are no hotel or motel chains located in Damariscotta or the neighboring towns. However, the region has many quaint 'bed & breakfast' accommodations and a plethora of vacation rental options.
