Bos Sauna is a wood-fired sauna at Sennen Cove in the far west of Cornwall. The venue describes it as a small space at the edge of the cove overlooking the Atlantic, with the sea used for cooling off between rounds.
Session times change with the tides and the seasons. Available seats are shown in the online booking calendar and the weekly opening times are posted on the venue's Instagram account. Check the venue's website for prices and a regular timetable.
There is a small changing area and the venue asks visitors to arrive with swimwear on. It suggests bringing two towels, water, sliders and a changing robe.
