Sauna Ostara is a wood-fired horsebox sauna nestled on the tranquil shores of Nairn. The name “Ostara” comes from the Celtic wheel of seasons and means a time for rejuvenation, balance and connection, a fitting alignment with the restorative experience we aim to offer. Converted by Fynn, Madeleine & Clare this cozy retreat invites you to unwind, reconnect with nature, and experience the timeless healing power of heat.
