Hot sauna. Cold river. Proper reset.
The Experience
Nestled on the grounds of historic Slane Castle, our riverside sauna and stand-up paddleboarding centre on the Boyne offers the perfect mix of adventure and relaxation. Enjoy a 50-minute sauna session interspersed with refreshing dips in the river or the calm, sheltered stretch of water created by the old 18th-century canal embankment. For a full riverside day, pair your sauna with a SUP session from our on-site centre — the perfect combination of exhilaration and relaxation, with coffee, snacks, and a cosy hangout space to complete the experience.
