Eir Sauna was born from a simple idea - to create a space where people can slow down, breathe deeply, and reconnect with nature. Tucked away on the edge of Loch Long in Arrochar, Scotland, our wood-fired barrel sauna blends the age-old tradition of heat and cold therapy with the wild beauty of the Highlands.

Step inside and feel the warmth of the fire wrap around you. The scent of natural wood fills the air as you take in lochside views through the sauna’s curved walls, and from the circular window, gaze out to the dramatic peaks of the Arrochar Alps. When you’re ready, step outside and awaken your senses with a plunge into the cold, clear water of the loch, a dip in our plunge bath, or the exhilarating rush of our cold drench bucket.

We believe in the power of contrast - heat and cold, stillness and movement, connection and solitude. Whether you’re here for quiet reflection, to share laughter with friends, or to recharge after a long day, Eir Sauna offers a moment that’s yours alone.

This isn’t just a sauna. It’s a ritual, a reset, and a reminder of how good it feels to be alive!
