We felt like we were on another planet. It's unlike anything I've seen. Very cool place and you can pretty much see it all in about an hour.

A relatively easy hike with views of the many types of rocks formed in a volcanic flow. Definitely recommended

Was a steep hike. The parking area is very small and one entrance and exit. There is a hike up a hill to get to the obsidian. Great views! Hot no shade, we did see some not melted snow! Toatally worth it!!!

The road to get to Obsidian Dome is unpaved for the most part. Best to go with 4WD. It's not a must do, but it is interesting.

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
