Grape Creek Warm Spring
Grape Creek Warm Spring flows at only 72°F on BLM land near Burley at 5,136 feet, making it a warm spring rather than a hot one. What it lacks in temperature it compensates for in mineral content: 350 mg/L chloride, 250 mg/L sodium, and 200 mg/L sulfate create water with a distinctly mineral taste and feel.
The spring sits just off Narrows Road in the open rangeland of Cassia County, where sagebrush and bunch grass dominate a landscape shaped by wind and sparse rainfall. At 14.6 inches of annual precipitation, this is dry country. The terrain rolls gently between the Snake River Plain to the north and the Albion Mountains to the south. The water emerges at ground level, barely warm to the touch, pooling in a modest depression surrounded by alkaline soil.
The water chemistry points to deep circulation through Paleozoic sedimentary rock rather than the volcanic systems that feed most Idaho thermal springs. High calcium at 140 mg/L, paired with substantial magnesium at 29 mg/L, indicates prolonged contact with carbonate formations. The 72°F temperature is only 23 degrees above ambient air, suggesting either a shallow circulation path or significant cooling during ascent.
This is primarily a geological curiosity rather than a soaking destination. The 72°F water barely exceeds body temperature and is too cool for comfortable bathing in most weather. Access is easy, just 230 feet from Narrows Road. Independence Lakes Campground lies about 17 miles away but is free and does not require reservations. No facilities exist at the spring itself.

The water at Grape Creek Warm Spring is alkaline (pH 9.4). It is notably rich in calcium (may support bone density and joint health), sulfate (traditionally used for skin conditions and inflammation), and chloride (natural antiseptic with skin health benefits).
