The Symbol Bridge Cave Pictographs are located in the Lava Beds National Monument near Tulelake, California. The cave is at the end of a well maintained trail just under 1 mile from the trailhead. About 3/4 of a mile from the trailhead you can also stop at Big Painted Cave to see a few more pictographs.
For turn-by-turn directions to the trailhead enter Symbol Bridge Trail into your driving app.
Included with this post is the GPS file and map that we plan to use for our first visit. If you don't want to wait for us to get around to it feel free to try the GPS file and map for yourself. With no guarantee, of course, but they most often prove valuable for us.
