    Short hike to the top of a volcano. You really get the idea of what's it like to be a volcanologist. Never seen so much obsidian in my life. Pieces the size of dinning room tables. If you're not into rocks, don't go. If you can stretch your imagination, go for it. Dirt road going in.

    Great place to explore but there are no interpretative boards available for review. Lots of areas to explore but be careful there are many sharp rocks. The hike up to the dome was short and easy. The dirt road to the trailhead was also easy and doesn't require 4x4. If you like geology then you need to stop and check this out. If you really want to see lots of different types of volcanic rock then you must check out Panum Crater near Mono Lake.

    Another geological play zone created by the volcanic activity in the eastern Sierras. Not a bald dome like Half Dome, but a giant mish-mash of shattered rocks. I assume the Obsidian Dome was mined which is why it looked like a huge pile of rubble. It still had an otherworldly feel and reminded me of the documentary, "Manufactured Landscapes". Of course, I enjoyed seeing the boulders of obsidian. Most have plenty of impurities and a matte finish, but there are few that have a smooth, shiny, black surface. Internet maps don't always pinpoint the correct location. Located 16 miles south of Lee Vining, exit at the sign for Obsidian Dome Road along Highway 395 and follow the dirt road for 1.7 miles. This means driving past the marked parking area on the north side of the dome. Instead, continue to the west side of the dome which has the best obsidian and park near the gate. Walk around the gate and up the gravel road. From base to top is about a 400-foot elevation change. The visit took 25 minutes.

    Get ready for some moon-like adventuring. The top of Obsidian Dome is covered with rock piles and little pathways that curve around the stacks like mazes. The rocks themselves range from tan to black, and if you don't look at the beautiful distant mountains, you just might think you're on the moon! Or maybe that's me getting in touch with my childhood imagination. The rocks range from gigantic (bigger than an adult) to tiny little pieces that serve well as souvenirs. Some of them are the perfect size to put in your pocket! The patches of obsidian are shiny and metallic-looking in the sunlight. It's fun to scramble all over the rocks. Just beware of the ones that are a bit shifty. Take the Obsidian Dome exit off the 395, and there's a clearly-marked dirt road that leads you to the parking lot for Obsidian Dome. The road is pretty smooth with some occasional rocks. Our 12-passenger van made it just fine. If you walk about 10 minutes further down the road after you park, you'll find a gated-off service road that you can walk up to in order to reach the top of the dome. OR if you're adventurous like my teenage siblings, you can climb up the side of the dome itself, picking your way among the rocks. Don't worry; they all got there safely and none of the rocks shifted or fell. Like another reviewer said, there is NO shade up there. So bring your water, hats, and sunscreen! And maybe some snacks, depending on how long you want to hang out up there. We spent about 3 hours there total, between clambering over the rocks and then trekking to the nearby creek, speaking of which... Side note: if you're hoping to get refreshed by the nearby Glass Creek, as of late June it's just a stagnant strip of green water. Not worth the walk there.

    Construction on Thursdays = Major Delays. Not recommended for families with babies or toddlers…read more We arrived at the Village at 8:30 a.m. to catch the 8:45 shuttle to Devils Postpile, only to be told the first shuttle was delayed until 10:05. Since we were already committed, we drove to Main Lodge instead, where we found a huge line from everyone waiting on the delayed shuttles. At every step, we asked staff for updates, but no one warned us how bad the delays would be. We were told the shuttle ride would take about 20 minutes, but it ended up taking over an hour because of stop-and-go traffic from construction. The return trip was even worse. We boarded the shuttle at 1:30 p.m. and didn't get back to Main Lodge until after 3:00 p.m. The shuttle was hot, overcrowded, made multiple stops, and even returned to Devils Postpile before heading back. Staff seemed just as uninformed as visitors, and no one could provide accurate wait times or expectations. Our timeline: * Arrived at the Village: 8:30 a.m. * First shuttle departed: 10:05 a.m. * Reached Devils Postpile: Just after 11:00 a.m. * Boarded return shuttle: 1:30 p.m. * Returned to Main Lodge: Just after 3:00 p.m. The ticket agent refunded our shuttle tickets and admitted they didn't realize how severe the delays were because multiple agencies are involved. If you're traveling with young children, especially babies or toddlers, I'd avoid visiting on Thursdays during construction. It turned what should have been a simple outing into an exhausting, all-day ordeal.

Ample parking in dirt lots. Cool info signage about the area. Seeing this phenomenon was amazing. Two miles further to Rainbow Falls. Devil's Postpile is closed 10/6-10/11, major road work repairs.

    The first time I visited HorseShoe Lake, the lot was packed, and the hike was no joke! I was out of…read moreshape, and there was still a lot of snow on the trail in July! It was tough. My cousin even had a close call when he accidentally slid off the trail, ran down 100 feet, and narrowly missed hitting trees. (Slipper snow) Despite the challenges, the reward at the top was well worth it. It was a beautiful, secluded lake. Some of us tried a little fishing, while the girls jumped into the freezing cold water for a swim. The water was so "pristine" that my hair felt conditioned afterward. It was magnificent, the water felt untouched and almost holy! This past summer, we hiked it again for the 4th of July, and it was so much easier because I had lost 20 pounds, haha! I'd say the hike is about 13 minutes up, around 2 miles round trip, and great for all ages. Just make sure you're in decent shape and don't have any serious health concerns. When I was 20 pounds heavier, the hike felt like a 10/10 in difficulty. Now, it's more like a 3/10, a total breeze!

    When you arrive, you see a bunch of dead tree and the waterline really low. Your first impression…read moreis "huh. But as you walk around the lake, you're surrounded by beautiful lush green pines. Small quaint bridges over stream beds. The wind in the trees with a beautiful view of the lake and its surroundings. It's a very easy straight walk. Highly recommend
