We enjoyed an unplanned side trip to obsidian dome. About 2.7 mi from the highway, the road is unimproved. We made the trip easily in a small SUV. We saw obsidian and petrified wood. It was a fun and interesting trip

Having gone to Mammoth several times this was our first trip to Obsidian Dome and it was amazing! I have two young children 6-9 who were able to do the short hike up the mountain and they loved it.

Easy dirt road drive into a very beautiful environment. It is breathtaking and amazing to see. The road continues up to some very beautiful streams that were wonderful for picnicking. Great 1/2 day trip.
