The hot springs are located on the south banks of the Halfway River, about 30 kilometres north of Nakusp. Travel east on the Halfway River forest road, from Highway 23, for 11.6 kilometres (at the 11 kilometer flag) where an old logging road branches left, down slope. Walk about 70 metres down the old road then look for a steep trail down over the bank. Follow the trail down to the river then walk downstream for about 100 metres. See Woodsworth (1997) for details.

Numerous springs flow from river gravels and are covered at high water. The springs bubble up out of the valley gravels adjacent to the river; the main pool is at the base of a prominent bluff. The springs are variably 41.8 to 60.5 degrees Centigrade with a flow of 3 litres per second and a pH of 7.14 to 7.87. These springs are part of the Upper Arrow Lakes area hot springs. The hot spring fluids appear to be driven by differential hydraulic pressure and heated by radiogenic heat generation.

Bedrock geology comprises lineated leuco-quartz monzonite of the Kuskanax batholith.

The hotsprings are not developed but have been maintained by volunteers from Nakusp.

A detailed description of the hotsprings is available in Woodsworth, 1997.
