Dip Garden Onsen & Ice Bath

What is it? An onsen-style garden spot in Ari and a true cold-water curveball. It actually only runs ice baths twice a week, but the daily event is paired with an easier going set of chilled pools – one a bracing 5C, one a gentler 15C – all roomy enough to move around in. Round it out with hot pools (38C and 42C), a sauna, a steam room, a chill-out room and the Yellow Lane restaurant for when you’re done.

Why we love it: The cold pool is the clever twist: you get the full cold-shock but with space to, unusually, share it. ‘You’re in up to the neck with room to move, not folded into a small tub half in and half out,’ says community programming manager David Baily. ‘There’s room for other people, which changes it completely – cold water is easier with someone next to you.’ Pair it with the hot pools, sauna and steam for a proper hot-cold circuit. All of it outdoors, under gorgeous trees. It’s mixed-gender, swimwear-on and low-key.  The food, from on-site restaurant Yellow Lane, is a cut above the usual.

Time Out Tip: For a guided plunge rather than a solo soak, come for the Thursday ice-bath and breathwork session (7pm-9pm) or the Sunday open session (11am-2pm).
