More than just a hole in the ground, the Guler Ice Caves are a hidden gem located a few miles…read moresouthwest of Trout Lake along NF-24 in the Gifford-Pinchot. It's a day-use site (re: $5, no camping allowed) with a small packed-dirt parking area, a few trails and picnic tables, and the aforementioned caves, which are situated just to the left (re: east) of the parking area as you enter, which is not immediately apparent, especially if there are cars already parked there; for some reason, no signs in the immediate area point you in the right direction, so you may struggle to find it, if you don't know where to look.
Below ground level, the caves act as a heat trap, keeping temperatures at or below freezing all-year round: even on an 85 degree day like the one during our visit, the cave is absolutely frigid, slick, and somewhat dangerous to traverse, and more extensive than it first appears. You might be tempted to believe that the semi-circular chamber just below the entrance stairs is all there is to the cave system, but a careful look at the map on the marker display above reveals deeper, more exciting chambers, such as the crystal grotto, further in either direction. Hard-hats, boots with good traction, flashlights, cold-weather clothing, and probably knee-pads (in case of highly likely slips, trips and falls) are recommended beyond the main chamber.
I've been wanting to visit here for some time, but as we were inadequately prepared for the environment, we did not venture far beyond the entrance; a mistake I guarantee will be corrected during our next visit. Also important to note that the caves are virtually inaccessible during the winter without some sort of vehicle capable of traversing heavy snow, as we encountered last April during an attempted visit, only to find the roads completely blocked by a wall of ice and snow. Wait until late spring or early summer, when the snowpack has melted, before trying to visit in a car or truck.
