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.

There are several ways to get here, ist thru Lava Beds National monument - it is a 15 mile dirt road, my husband wasn't thrilled with more dirt roads so we continued down past the visitor center in Lava Beds on route 10 then turned west at Tionesta intersection and continued west - there are two dirt roads leading up...

If you enjoy learning new things, then visit. It is fascinating how this came to be. That being said, be careful. The rocks are razor sharp and nothing preventing your kiddos from climbing up them- except responsible parenting. One slip or misstep and it will be an emergency!

I've been here several times and always enjoy Obsidian Dome. It's a short drive down a very good dirt road right off of US 395, on the way to Mammoth Lakes from June Lake or Mono Lake. You can scramble up the dome, or drive a little farther down and walk up an old road (apparently from a pumice mine)... More

We had been to Obsidian Dome several times but never went up to the top. The trail is well maintained and a vert walk. Once on the top, endless piles of boulders and rocks, weird magma flow patterns...an other world. Because of the nature of the rocks and being glass like based, walking on the smaller chunks sounds like walking... More

We visited Obsidian Dome based on the reviews on this site. I am so glad we did. It was a little hard to find. The road is very ruff and not well marked. When you get to the top of the dome, it appears like a different planet.

The dome is definitely a different place. Make sure to bring some water with you 'coz on the top of the dome it is very hot and there is no water around.

I've been here before, but it was many years ago. The road is a single lane, grated dirt road with rocks, ruts, loose dirt and whoops in some areas. I went in my Kia Optima and it was a little on the scary side for such a low clearance vehicle. I wouldn't recommend driving in a low clearance car. The... More

It is beautiful from the bottom, but hike to the top and be transported to another planet. It is a short easy hike but bring a hat because there is no shade.

When my grandparents owned a lodge in Mammoth this was my grandpa's favorite place. We always stop and poke around anytime we head that way. It's beautiful in itself and the trees and surrounding area are very pretty and peaceful. It's an easy drive off the highway so a good place to take a break.
