A primitive hot natural mineral bath called Kosk Hot Springs can be found on the banks of Kosk Creek, about two miles north of Big Bend. There is no cost to use the hot springs, which are accessible to the general public despite being privately owned.
Natural Hot Springs
The Kosk Hot Springs is next to a moving river and have one main geothermal pool with cement rock walls. On the other side of the riverbend lies Hunt Hot Springs, which is a short stroll away with four different hot spring pools.
When the hot springs water emerges from the cracks between the rocks and feeds a stream-adapted man-made rocky pool, it is approximately 110 °F. The pool water temperature is a pleasant 100 to 110 °F (the exact number varies with the season and other factors). Up to three people may soak comfortably in this pool.
The water is all-natural and clothing-optional, but be aware that people do pass through for hiking and soaking.
No camping is permitted by these springs. The owner of the land graciously lets visitors come to soak, so people need to pack in and out.
Leave your vehicle at the Kosk Creek Bridge and trek 0.7 miles to Hunt Hot Springs, then another 0.25 miles to Kosk Hot Springs.
