A fine summer day on a cool Maine lake....

The water view of the dock from the deck.

You can bring your own boat. We’ve got free island dock space, a free public boat launch, and free parking. No boat? No problem. You can paddle one of our canoes or kayaks (also free). It’s about a 30 minute journey from or to shore (for intermediate paddlers - weather permitting). If weather doesn’t permit, you can take a free pontoon ferry (regular service is 10a, 3p, and 5p. And if those times don’t work for you, then we can run a special ferry service at whatever time you want for $50.00.

Telling work where you are working from is up to you! 5G reception, wireless hotspot, inverter to power cell phones and laptops, and rechargeable batteries means we do remote work from the island (shhhhh!).
