Emerging from the sage plains where rural northern Nevada skirts the southern Oregon border, Bog Hot Springs is less a typical hot spring pool and more of a large creek with several hot pockets bubbling up that essentially warm the entire creek.
The creek has been dammed up in several areas to create pools that are about thigh deep. The creek cools as it flows, so if the hottest source area, which bubbles up at about 120 degrees, is too hot, then just head downstream until you find an area suitable for your taste.
These springs are primitive, and aside from the remnants of some past damming, there are no amenities whatsoever at the springs.
There are several spring sources along here, and the temperature in the creek can fluctuate up or down depending on where you are in relation to them. A larger pool at the lower end is about 105 degrees, and the hottest pool, visible by an abundance of steam rising from the creek bed, sits about a quarter mile upstream.
Unlike a normal stream, Bog flows through a channel with vertical walls that is nearly invisible until you drive up next to it. It is hard to see as you're approaching, but if you park in the large parking areas you'll notice it pretty quickly.
Bog is in a part of the state that sees few travelers, but it can be a great addition to a trip to Sheldon Wildlife Refuge.
Gas availability in Denio is an off-and-on affair, so the nearest sure sources of gas are in Fields or Adel, Oregon, and the Paradise Valley junction in Nevada. Plan accordingly.
