1 Big Sustainable Island

Your Off-Grid Maine Island Experience is Here.

Annabessacook Lake has a way of pretending it's humble — right up until you drop a line in. This world-class Maine fishing lake sits at the heart of our private island glamping retreat, quietly daring guests to test their luck between hammock naps and canoe laps. Mornings arrive with mist, loon calls, and the kind of calm that makes even casual anglers feel wildly optimistic. It's the sort of glamping in Maine experience where the fish don't care about your schedule… and the island encourages that.

Annabessacook Lake sits in Monmouth, Maine, near Winthrop and the Winthrop Lakes Region.

Overview of Annabessacook Lake

Down below, the locals are plentiful and opinionated. The lake is home to largemouth and smallmouth bass, chain pickerel, white and yellow perch, crappie, sunfish (bluegill and pumpkinseed), brown bullhead, and — just to keep things interesting — the occasional salmon and brown trout cruising through like they own the place. Fish from the dock, a canoe, a kayak, or a paddleboard during your off-grid lakefront glamping Maine stay. No stocking trucks. No crowds. Just a healthy lake, a little mystery, and a strong possibility you'll exaggerate the size of that last catch once the fire gets going.
