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.

We went close to sunset and it was a fantastic time to observe the obsidian. The road down is difficult and only recommended for 4-wheel/all-wheel drive. The loop around take about 45 minutes.
