Weighing up Onsen Hot Pools vs The Spa at Millbrook? This article compares two of the region’s best-known places to slow down.

Both sit a short drive from Queenstown, and both pair a hot pool soak with a rejuvenating treatment. Beyond that, each builds around a different idea.

Onsen Hot Pools & Day Spa is a boutique retreat above the Shotover River canyon. There, every cedar-lined hot pool is exclusively yours for the session. The Spa at Millbrook, by contrast, is a resort spa inside the Millbrook Resort near Arrowtown.

Onsen Hot Pools & Day Spa: an escape built around the soak

Onsen sits ten minutes from Queenstown CBD, perched above the Shotover River at Arthurs Point. The setting is the point: a quiet hillside, cedar-lined hot pools, and the canyon unfolding below in full, unhurried detail.

Every session is exclusive use, so the pool, the view and the silence belong to you for the hour. During the day, sunlight pours across the cedar. After dark, glowing Japanese lanterns and soft lighting take over beneath the southern stars.

Onsen weaves the day spa into the experience rather than bolting it on. The Original Onsen + Treatment and Oval Onsen + Treatment experiences begin with a 45-minute soak. Then you are invited to enjoy a luxurious 1- or 2-hour spa treatment. 

Signature treatments draw on Aotearoa: Rotorua thermal mud, Manuka honey and Kawakawa balm, delivered by award-winning therapists.

For contrast bathing, the Tri-Bathing experience has its own exclusive space above the river. It moves through a eucalyptus steam shower, a hot pool with hydrotherapy jets, and finally a cold plunge. The World Luxury Spa Awards named Onsen a Winner in 2025. Onsen also holds a 2026 Travellers’ Choice Award on Tripadvisor.
