About this spring
Maruia Hot Springs is a tranquil, Japanese-style eco-resort located in the scenic Lewis Pass national reserve along the Maruia River. The mineral-rich waters flow directly from subterranean paths into open-air rock pools, indoor bathhouses, and thermal steam rooms. The water is heavy in sodium, bicarbonate, and natural boron, providing a remarkably slippery, skin-softening sensation that mimics traditional Onsen. The resort operates on 100 percent renewable hydro energy generated on-site, complementing its deep focus on wellness, nourishment, and environmental sustainability. Guests can soak while enjoying panoramic views of the rugged Southern Alps and native beech forests. Footpaths link the pools to saunas, cold plunges, and an organic restaurant. This property is fully accessible and includes overnight lodging options.
Highlights
History
Tribal travelers originally used these remote waters for physical recovery while navigating the challenging sub-alpine routes of the Southern Alps.
The secluded river valley remained a basic wilderness refuge for many decades before visionary eco-conscious developers completely transformed the site in 1985. They designed an authentic Japanese-style eco resort that introduced one of New Zealand's very first dedicated outdoor onsen experiences to global wellness travelers.
Local guide
Leaving the coastal plains behind, you ascend into the rugged beech forests of Lewis Pass where the mountain road curves alongside the rushing waters of the Maruia River. You pull into a secluded river valley and instantly catch the faint, clean scent of pure geothermal minerals rising from the earth. The entire property mirrors a traditional Japanese onsen, blending dark timber architecture with the wild sub-alpine scenery.
You step outside into the open-air rock pools where the crystal-clear thermal water flows continuously without chemical treatment, creating a remarkably smooth, skin-softening sensation. As you soak, mist rolls low across the mountain river and the wind rustles through the dense native canopy just meters from the pool edges. Indoor pools and a cold plunge allow you to move between heat and cold in the onsen tradition.
Pack an extra change of warm clothes, non-slip sandals, and a refillable water bottle to stay hydrated during your soaking sessions. Booking your bathing pass in advance is recommended since the remote resort caps visitor numbers to preserve its sense of quiet and isolation.
Mineral chemistry
Bicarbonate springs cleanse and soften the skin surface, removing excess sebum without stripping the skin's acid mantle. Traditionally recommended for acne-prone skin and sensitive skin types.
Bicarbonate springs are generally among the most gentle and well-tolerated onsen types.

FREEWelcome Flat Hot Springs provides a highly rugged, backcountry wilderness soaking experience located deep within the Westland Tai Poutini National Park. The naturally muddy pools sit on an alpine terrace surrounded by snow-capped peaks, cascading waterfalls, and dense native fern forests. The thermal water bubbles out from the earth, rich in minerals, accumulating in natural gravel-bottomed mud pools maintained by the Department of Conservation. Accessing this remote site requires a demanding, multi-hour wilderness tramp along the Copland Track, requiring river crossings and steep climbs. A modern Department of Conservation hut and campsite sit adjacent to the pools, which must be booked well in advance. Sandflies are incredibly prevalent here, so packing insect repellent is mandatory.
