Maine’s extensive coastline provides habitat for marine mammals, making it a popular location for observing seals. These creatures are a common sight along the state’s shores, often resting on rocky outcrops and ledges. Visitors frequently seek opportunities to witness seals in their natural setting.
Common Seals in Maine Waters
The most common seal species found in Maine year-round is the harbor seal. These seals have small, rounded heads with large eyes and short snouts, often described as dog-like in appearance. They vary in color from brown to gray, with a mottled or speckled pattern across their bodies. Adult harbor seals measure between 5 and 6 feet in length and can weigh from 150 to 400 pounds.
Another year-round resident is the gray seal, which is larger than the harbor seal. Gray seals are distinguishable by their longer snouts, giving them a more horse-like or Roman nose profile. Males can reach lengths of 7 to 8 feet and weigh up to 800 pounds, while females are slightly smaller. While harbor and gray seals are the primary species, other seals like harp seals may also visit Maine’s waters seasonally.
Prime Locations for Seal Spotting
Seals “haul out” of the water to rest and sunbathe on various coastal features. Rocky ledges, offshore islands, and quiet shorelines are preferred basking spots for these marine mammals. Observing seals during low tide yields better results, as more of their preferred resting areas are exposed.
Several locations along the Maine coast are well-known for seal sightings:
- In the Portland area, seals can be seen from the end of Portland Pier or the Maine State Pier. Boat tours departing from the city, such as the Peaks Island Ferry or those heading to Halfway Rock, also encounter them.
- Acadia National Park, particularly Seal Cove in Tremont and various spots within Frenchman Bay, offers opportunities to see both harbor and gray seals.
- Further south, Kennebunkport is another excellent viewing location, with seals found near Goat Island Light and Goose Rocks.
- Many boat tour operators throughout coastal Maine, including in Bar Harbor and Boothbay Harbor, offer specialized cruises that bring observers close to seal colonies.
- Binoculars are recommended for optimal viewing from a distance.
Responsible Seal Viewing
Observing seals requires adherence to guidelines that ensure both human safety and the well-being of the animals. Maintain a safe distance of at least 150 feet (approximately 50 yards) from seals, whether they are on land or in the water. Approaching too closely can cause stress to the animals, potentially leading them to abandon their resting spots or, in the case of mothers, their pups.
Under the Marine Mammal Protection Act, it is illegal to touch, feed, or harass any marine mammal, including seals. Allowing pets to approach seals is also discouraged, as it can startle the animals and potentially transmit diseases. If a seal appears distressed, injured, or stranded, report it immediately to the Maine Marine Animal Reporting Hotline at 1-800-532-9551. It is common for seal pups to be left alone on beaches while their mothers forage, and these pups should not be disturbed or moved.
