This guidebook is your passport to the exhilarating world of wild saunas in the UK, revealing over 170 locations across the country. More than just a directory, this book explores the ancient roots of sweat bathing in Britain, from the burnt mounds of Shetland and the teach allais of Ireland to the modern-day resurgence of saunas, ice baths and wild swimming. It's about reconnecting with nature, rediscovering ancient traditions, and embracing the physical and mental benefits of heat and contrast therapy. Discover Sawna Bach, on the wild coast of Anglesey, where you can add on beach yoga or feast on homegrown food after your session. Journey to the Isle of Arran with Drumadoon's vintage sauna truck, and soak up salt-flecked coastal views and a taste of Celtic history. Experience the magic of Fallen Willow Sauna, tucked away in a secluded woodland near Stockbridge, a testament to thoughtful design and community spirit. And venture north to Shetland, where Haar sauna, overlooking the wild beauty of St Ninian's Isle, offers a sanctuary for locals and travelers alike.
