as a geology enthusiasts, this is one of my favorite hikes in the mammoth area. as long as you stay on the trails, I agree that this is an easy hike. be careful if you're using Google maps as your trail guide. one of their trails led me to a cliffside with boulders no smaller than 1 m across. twice I've made this hike about an hour and a half before sunset and twice I have gotten caught in the dark.

It’s really cool trail with a ton of rocks! Also, if you’ve ever seen Starship Troopers, pretty sure the final battle was filmed here. We did park by the gate & hiked around. Also, it’s not crowded.

Go farther down to start it just before the gate and you can cut off half mile.

HikingGreat!No shadeRocky

Mindblowing trail - the obsidian is phenomenal looking. It looks like you stumbled upon a volcano that just blew with huge chunks of black glistening rock thrown around. We hiked mid-morning (around 10 am) on a Friday and didn't pass any other hikers. It was our first day in the area, so we felt the elevation change and hiked at a slower pace. The road leading up to the trailhead is a bit bumpy and rocky. If the trailhead is busier, you may run into parking issues. Dog-friendly hike - trail is well-established.

Very cool trail! A geologist dream site! Piles of obsidian ( blk rocks, volcanic glass) that seem like it kept going for miles! Looks like you’re on the moon or another planet! Such a cool experience! Love it! Great trail for kids & family!

Started my hike from the service road at Hartley springs, reccomend hiking poles and proper snow shoes. With that said conditions were beautiful the snow was fairly packed so it wasn’t too bad. View from up top was absolutely breathtaking!

This was a fun little side trip on our day trip to the Sierras. If you want to get to the good stuff (inside the crater), drive past the first little parking area and park near the gate and you’ll cut the walk to get into the dome in half. From there, it’s a short walk up the dome to get inside. Once inside you’ll be treated to a surreal landscape that looks like you’ve stepped off Earth and onto another planet. My son had a blast exploring the rocks inside the dome and didn’t want to leave.

Great short hike to the top. Not much cover so it can get pretty hot on a clear day, although there are some areas where a strong cool breeze blows through. The road leading up to the trailhead is narrow, rocky, and uneven, so take your time and be careful of oncoming traffic and kicked up rocks.

I saw two trails to get to the top. We drove past the first one and went to second. It is an easy walk to the top and if you like geology or volcanology a pretty cool spot.

Went with my hubs, 3 kids and dog. I would recommend not bringing your dog unless you have shoes for it. The rocks are very sharp and will cut there pads. Wear shoes with good tread. Overall all a neat hike, lots of cool geology to look at.

Very neat geologic feature. You can walk around for a while on top of the dome as there’s really no defined trail

Took our kiddos and two dogs on this easy hike. We parked a little before the trailhead so our hike was a bit more than a mile. Once you get to the top, it's like being on the moon- a very unique landscape that's definitely worth the short hike. No shade but on the day we were there (June 2019) it was very windy so we were glad to be wearing long pants and jackets. There was even snow still present in the shady areas. We were careful of where we took the dogs since some of the formations had sharper rocks, but they seemed to enjoy the short hike.
