Maruia Springs is a small hot-spring resort on the banks of the Maruia River. The water temperature varies between 36°C and 42°C across a variety of pools, including outdoor rock pools, indoor baths, a sauna and a cold plunge pool. It’s a magical setting during winter (June to September) but mind the sandflies in summer (December to March).
New owners have recently invested in the resort with renovations and improvements including new outdoor bathing pools and private spas. Accommodation is available in simple but cosy rooms (doubles from $249); guests have 24-hour access to the pools. There's also an overnight campground and a cafe with a sunny deck overlooking the river. It's 6km west of Lewis Pass.
