An old ice fishing shack, rebuilt for heat.
Fillet Chalet is a wood heated sauna. Seating for up to six people.
Sessions
How to get in.
40 minutes. Two good rounds, a cool-down break, and a story to tell. The right way to try this for the first time.
Book intro →75 minutes. The full experience — co-ed, women-only, and queer sessions available.
See schedule →Exclusive use at Bug Light for up to six people. Good for couples, small celebrations, and people who want the place to themselves.
Book private →We deliver to your property — waterfront, campsite, backyard. Yours for the night.
Get in touch →The Ritual
Hot. Cold. Repeat.
The Finns have been doing this for a thousand years: get as hot as you can tolerate, then go somewhere cold. In Maine, "somewhere cold" is never far.
At Bug Light Park, you're steps from the harbor. Bring a towel, bring your people, and plan on staying longer than you expected.
