Here’s a complete overview of Maruia Hot Springs, one of New Zealand’s beautiful natural thermal spring destinations:

Maruia Hot Springs is a natural geothermal hot springs resort, wellness spa, and relaxation destination tucked into the snow-capped Southern Alps in the Lewis Pass National Reserve on the South Island of New Zealand. It’s known for its mineral-rich geothermal waters, serene mountain setting, and a focus on wellbeing and sustainability.

The springs are natural geothermal mineral waters that rise from deep below the earth’s surface (~56 °C) and are cooled to a comfortable soaking range of about 37 °C – 42 °C.

The water contains minerals and can change color throughout the day (from clear to green, grey or black) due to natural elements — including harmless “black algae” that’s said to have skin benefits.

These springs provide a chemical-free bathing experience with large volumes of fresh geothermal water flowing through the pools daily.

Indoor and outdoor pools, saunas, steam rooms, and cold plunge options help provide a full thermal bathing experience.

The resort offers wellness programs, massages, yoga and other relaxation activities, and daily spa treatments.

There’s a restaurant and cafe on site serving meals with local ingredients.

You can visit for a day or stay longer. Options include:

Hotel rooms — comfortable rooms nestled within the resort

Glamping pods — heated glamping style stays with views of the river and mountains

Campground (seasonal) — basic outdoor camping access (varies by season)
