In winter, there's nothing better than relaxing in a hot tub after a day outdoors.
Hot tubs are a dime a dozen — inside B&Bs and hotels. But the ones outside? Much harder to find.
I love the hot tub at Maplelag cross-country ski resort in western Minnesota. We ski all day, then collapse into its giant tub — the largest in the state — and chat with fellow skiers until the warmth and steam lull us into a happy stupor.
When Maplelag built its new lodge, it put a retractable roof over the tub and sliding-glass doors on the sides. Luckily, bathers still can catch a breeze and get snowflakes in their eyelashes.
People love outdoor hot tubs, but they're hard to find because they're such a pain to maintain. Hosts have to continually check pH balance, chlorine levels and the filtration system, a process that discourages many resort owners.
Farther up the North Shore near Grand Portage, the hot tub on the rocky shore outside Rick Anderson's Sweetgrass Cove Guest House has practical uses.
"It's therapy,'' says Anderson, a certified massage therapist. "Most of my guests are from the Twin Cities, and after five hours of driving, that's the first place they go.''
He explains that the jets are there for a reason: "Hydrotherapy with any kind of percussive motion does relax you, just like a massage does,'' he says. "The heat takes away pain in some cases, stretches out muscles and increases circulation.''
It's not that easy to find an outdoor hot tub these days. The one at Wisconsin's High Point Village resort, where I soaked gratefully after nearly getting lost on the Ice Age National Trail, is gone.
And the outdoor tub is gone at Thayers Inn in Annandale, Minn., where I once did a post-mortem on that evening's murder-mystery dinner with the murder victim and his wife.

Rental cabins and houses
It's easier to find outdoor hot tubs at private rentals. You can find them on city, regional and state web sites (see Renting a vacation house).
Many people rent directly from owners through such worldwide services as VRBO, Vacation Rentals by Owner, which has a huge number of properties in the region, and HomeAway, whose web site has an advanced-search function that makes it easier to find a property.
