A short interesting hike leading to the center of a Volcano with spectacular obsidian and other volcanic rock. Amazing views of jagged formations and the High Sierra rising in the distance. Plenty of room to explore once inside the volcano.
You drive down a maintained dirt road for a mile or so until you come to an open area marked as parking for Obsidian Dome. If you are feeling adventurous, you can begin the relatively short ascent up the steep and rocky side of the Dome from the parking lot. Alternatively, if you head further down the road you will eventually discover an access road carved into the side of Obsidian Dome, closed to vehicles and suffering some neglect, but readily accessible by foot.
