With the summer sun getting ever warmer, swimming is a great way to cool off. If you know where to go, Acadia National Park and surrounding communities offer opportunities for cool dips in salt water, fresh water, or man made pools.
- Sand Beach open to swimming Memorial Day to Labor Day
- Echo lake open to swimming Memorial Day to Labor Day
- Glen Mary Wadding Pool, days and times vary
- Swim at your own risk in streams, lakes and ponds
- Pay attention to posted signs and restrictions near local water supplies
Sand Beach
The free bus service, the Island Explorer, stops here frequently during the summer months. It is the only recommended area on the island for ocean swimming, if you’re up to the thrill of 50 degree water. A lifeguard is stationed at the beach from Memorial Day to Labor Day and bathrooms and changing stations are provided.
Echo Lake
If you’re seeking a warmer swim then Echo Lake is your fresh water option. A life guard is also on duty at this swimming location.
Hiking up Sargent Mountain
Take a swim in the refreshing water of Sargent Mountain Pond, claiming to be the oldest lake in Maine; it is naturally fishless, being one of only two acidic lakes in the park. According to local folk lore the “Lake of Clouds” is not only bottomless, but home to a serpent. This is truly a “wild” mountain lake. Swim at your own risk, but please, don’t swim alone.
Bar Harbor
In the town of Bar Harbor, Glen Mary wadding pool is free for public use. This man made pool is only a few feet deep. It is great for young children under parental supervision. A lifeguard is sometimes available; please contact the Bar Harbor Chamber of commerce for dates and times.
The rare find
Many streams and forest ponds have been modified by locals over the long history of the island to provide hide away swimming holes. If you’re daring, ask around and you might be led to one. Please take note when swimming in any lake, pond or stream, of any posted signs. A number of island lakes serve as public water supplies and swimming activities are restricted.
