Birch Cabin has a hot tub that can be rented separately here.

Our wood fired hot tub needs a little TLC to get going. You have to keep an eye on the fire and stoke it up every half an hour especially in winter. The hot tub takes about 3 hours to heat up but once hot and if you keep the insulated lid on, it will retain it’s heat for ages and will only need a few small fires to give the temperature an added boost.
