Credit: Aislinn Sarnacki<\/p>\nOwls, deer, sea anemones and loons \u2014 wild animals are everywhere in Acadia National Park. As a longtime visitor and hiking guide there, I\u2019ve experienced some amazing wildlife encounters over the years, including a few this winter.<\/p>\n
Covering more than 49,000 acres of varied coastal habitat, Acadia is an ideal place to view wildlife for many reasons. For one thing, hunting isn\u2019t permitted. Pair that with constant foot traffic on park trails \u2014 about 4 million visits annually \u2014 and you get wild animals that are fairly used to people. I\u2019ve never seen such bold red squirrels and unbothered white-tailed deer.<\/p>\n
One winter, I was hiking down to The Tarn from the Beachcroft Trail when I walked into the midst of five grazing deer. One lifted its head, stared at me, then kept right on nibbling frozen branches. I sat down in the snow and watched the herd for several minutes, admiring their fluffy winter coats before continuing on my way.<\/p>\n
Deer are everywhere in the park. In summer, I\u2019ve spotted bucks with velvety antlers. In spring, I\u2019ve seen fawns trailing behind does. I\u2019ve watched deer wander the rocky beach near Seawall Campground and leap over the boardwalk on the Jesup Path.<\/p>\n

But that\u2019s not all. Acadia is home to at least 40 species of mammals, according to the park website<\/a>. While hiking there, I often observe beavers swimming in ponds, gnawing down trees and building lodges. I\u2019ve also come across snowshoe hares, noisy red squirrels, adorable porcupines and playful otters.<\/p>\n Visitors to the park often ask rangers and guides about one animal in particular: Maine\u2019s famous moose. Unfortunately, these iconic creatures are rarely spotted in Acadia.<\/p>\n Why? Mount Desert Island \u2014 where the main portion of Acadia is located \u2014 doesn\u2019t have the space for a moose population to thrive, according to an article posted on the park website<\/a>. In addition, transient moose rarely wander onto the island because they either have to walk across the motor causeway or swim. While moose are proficient swimmers, strong ocean currents and mudflats create additional hurdles.<\/p>\n Parkgoers also frequently ask about black bears, another celebrated species in Maine. While Acadia is home to a small population of bears, they\u2019re rarely seen by visitors because they tend to avoid people and dogs. I\u2019ve never seen a bear in Acadia.<\/p>\n If you\u2019re interested in sea creatures, that\u2019s easy. Just visit a beach at low tide and gaze into the tide pools. These pools of salt water, located between the high and low tide marks, contain a variety of crabs, sea stars, barnacles, periwinkles, dog whelks, limpets, anemones, marine worms and other aquatic animals<\/a>.<\/p>\n Some fantastic tide pools in Acadia can be found along the shoreline accessed by Wonderland Trail, Ship Harbor Nature Trail and the sand bar leading to Bar Island.<\/p>\n While tide pooling, you\u2019ll likely see a variety of seabirds floating just offshore. Keep an eye out for seals as well. Harbor seals and gray seals are the most common. They pop their heads out of the water as they swim and can often be found lounging on rock ledges.<\/p>\n Whale watching boat tours offer another opportunity to spot seabirds, seals and whales. The Bar Harbor Whale Watching Company<\/a>\u00a0reports that humpback, minke and fin whales are most commonly seen on their tours, along with Atlantic white-sided dolphins and harbor porpoises. They also occasionally spot ocean sunfish, bluefin tuna, blue sharks and basking sharks.<\/p>\n Seabirds seen on boat tours include northern gannets, shearwaters, storm petrels and fulmars. Puffins \u2014 which are highly celebrated in Maine \u2014 do not live on Mount Desert Island. However, during the summer you can book a boat tour to one of Maine\u2019s few islands with puffin colonies. The closest is Petit Manan Island, about 35 miles east of MDI.<\/p>\n Birding is an especially popular activity in Acadia. Each spring, the Acadia Birding Festival draws people from around the world to search for the park\u2019s many feathered residents \u2014 338 species, to be exact. Fan favorites frequently spotted include bald eagles, ospreys, great blue herons, common loons and a wide variety of colorful warblers.<\/p>\n![\"\"](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/03\/Sargent121324-26-600x400.jpg\")
