Tenakee Hot Springs: Alaska's Free Island Bathhouse You Can Only Reach by Water

Tenakee Hot Springs costs nothing, runs at 107 degrees Fahrenheit, and has been pulling people to the head of Tenakee Inlet since long before Alaska was a state. The spring feeds a rustic public bathhouse in Tenakee Springs, a community of roughly 100 residents on Chichagof Island, about 40 miles southwest of Juneau. There are no roads in. You arrive by ferry, floatplane, or private boat, walk a gravel lane past houses and fishing skiffs, and step into water the Tlingit soaked in for generations before miners and cannery workers built a bathhouse over the source in the late 1800s. The bathhouse is open year-round, clothing-optional, and run on a schedule posted at the door that locals fully expect you to read and follow. That is the whole deal: pure geothermal water, a deep soaking tub, a working fishing village, and no fee to get in.

The spring and the bathhouse

The water emerges from the hillside at the head of Tenakee Inlet at a steady 107°F and is piped a short distance into the bathhouse, where it fills a single deep communal tub. The flow runs continuously, so the water is not chlorinated, treated, or recirculated. It passes through and drains, and whatever you introduce goes with it. The building is a plain wood-frame structure a few steps from the shoreline, with changing rooms flanking the soak room and steam rolling out the propped door on cold days. The community rebuilt the current bathhouse in the early 1990s, but its job has not changed in over a century. This is a utilitarian soaking house, not a spa. There are no massages, no gift shop, and no day-use fee. Donations are accepted and go toward maintenance.

The name Tenakee is generally traced to a Tlingit word meaning "copper shield," and the head of the inlet was a gathering place long before European contact. The warm seep at the shoreline drew winter visitors. In the 1890s the site became a rest stop for miners working claims around the inlet, and the town grew around the spring the way desert towns grew around wells: first the bathhouse, then the houses, then the cannery. Today the soak is still the civic center of a town that has nothing else quite like it.

Etiquette and hours

Hours are posted at the entrance, and they matter. The schedule divides the day into sessions, traditionally split between men's hours, women's hours, and open sessions, and the pattern can change with the seasons and community decisions. Read the door before you walk in. Inside, the rules are unspoken but firm. Rinse off before entering the tub, because the water is untreated and flows straight through. Keep soap entirely out of the soak. Keep your voice low, because many locals come here for silence. For them the bathhouse is a living room, a therapy session, and a church all at once. Clothing is optional, and nobody cares which you choose.

On my last visit, I soaked through an evening session with the door cracked open, rain hammering the inlet, and a humpback whale surfacing just off the floats with a sound like a long exhale. The two other soakers, both locals, nodded once and said nothing, which was the whole point.

Getting to Tenakee Springs

Chichagof Island is the fifth-largest island in the United States, and not one mile of it connects to the continental road system. You arrive by water or air, and each option has its tradeoffs. Budget at least two nights, because every way of getting here is hostage to Southeast Alaska weather.

By ferry

The Alaska Marine Highway System serves Tenakee Springs from Juneau with a limited number of weekly sailings, typically a few round trips depending on the season and the current timetable. The run across Chatham Strait takes a few hours and is the cheapest way in. Walk-on passengers are common, and bicycles are welcome. Check the current schedule before you build an itinerary around it. Sailings shift seasonally, and in rough weather the small community dock can delay service. The ferry float lands you a short walk from the bathhouse, the store, and nearly everything else in town.

By floatplane

Floatplane service from Juneau runs about 25 to 30 minutes and lands directly on the inlet. It is the fastest route and the one most vulnerable to weather: fog, wind, and low ceilings cancel flights routinely, so book a round trip and build in a buffer day. Operators based at Juneau's harbor run charters on demand, and seats fill in summer.

By private boat

Boaters coming from Juneau transit Stephens Passage and Chatham Strait, a run of roughly 45 nautical miles that can be glassy or punishing depending on the hour. Moorage is available at the community floats, and tides and weather windows should dictate your schedule. Small-boat charter operators out of Juneau also run hot springs itineraries through the region.

A town built around hot water

Tenakee Springs is less a village than a shared driveway with a hot tub at the end of it. The main road is roughly two miles of gravel with no through traffic, because there is nowhere to go through to. Residents get around on foot, by bicycle, and by golf cart, and the pace of the place resets yours within an hour of stepping off the dock. The population hovers around 100 per recent census counts, a mix of commercial fishermen, artists, retirees, and people who moved here in the 1970s back-to-the-land wave and never left. There is a small grocery store with modest hours, a seasonal café, and scattered lodges and cabins for rent, some dating to the cannery era. The surrounding island holds one of the densest brown bear populations in North America, so treat every trail and berry patch with respect, and keep food secured. In summer and fall, humpback whales feed in the inlet close enough to hear from the bathhouse door, and seals haul out on the floats near arriving boats.

Planning your soak

The bathhouse runs year-round, and every season offers a different argument for going. Summer brings the easiest logistics: reliable floatplane windows, more frequent ferry service, twenty hours of daylight, and active whales in the inlet. Fall is the shoulder-season sweet spot, with fewer visitors and storm systems that make the hot water feel earned. Winter soaks are the most dramatic, with steam columns visible from the water and a real chance of aurora over the inlet, but travel becomes a genuine gamble as gales line up across Chatham Strait. Whenever you go, bring a towel, sandals, and quick-dry layers, since you will walk to and from the bathhouse in whatever the sky is doing. Carry cash for the store, bring snacks in case resupply is delayed, and do not count on cell service. Book lodging or a Forest Service recreation cabin in the surrounding forest well ahead for summer trips. Hydrate and pace yourself in the tub. 107°F is hot enough that most soakers cycle in and out. What you get in exchange is the rarest thing in North American hot springing: a free, historic, community-run soak at the edge of a wild island, where the price of admission has never changed and never will.
