At Arden Bathhouse, the colder it gets, the better it feels. Out here, on the edge of historic Richmond – just far enough away from city lights – the darkness feels bigger. As the sky darkens, move through a self-guided 4hr ritual: the deep heat of a wood-fired sauna, then the sharpness of a cold plunge. With senses heightened, sit back in a steaming hot tub, Bloody Mary in hand, under the stars. Duration: 4.30–8.30pm. Fixed price for 1–6 people.
