Lighthouses, working harbours and Atlantic islands

A journey through Acadia coast and the surrounding region brings the landscape into focus. Your ship connects the coastal places while guided excursions reveal the details that are easy to miss from the deck.
Choose the actual stops on the program, not just the destination name. Routes that include Maine lighthouses can offer a different balance of nature and culture from those centred on Newport. Activities, permits and walking demands vary by voyage.
When to go
Warm summer and the famous autumn foliage: harbour towns, lighthouses, coastal trails and whale watching in the Gulf of Maine.

Local conditions differ between coastlines and islands. The chart represents Portland, Maine, not every stop on a voyage. Cruise operation depends on the published itinerary, not the weather rating.
Temperatures in Portland, Maine shift clearly through the year: July is the warmest month with average highs near 28°C, while January is the coolest at around 1°C, a swing of roughly 26°C. Nights typically run about 9°C below the daytime high, so a layer for evenings is worth packing. The months between these extremes warm up and cool down gradually rather than abruptly.
