Be ready to huff and puff! Panum Crater is next to Mono Lake right off CA-120, what used to be one of the loneliest roads in America! The crater has two main trails: the Rim Trail and the Plug Trail. The Rim Trail will make you work for it on a hot day! Take a lot of water with you. The Plug Trail is somewhat easier, and depending on the time of the day you may get some shade at stretches. Do not try any of the unofficial trail, because you could easily get lost down there or get hurt walking over glassy volcanic rubble that covers your path. Both trails provide nice views of Mono Lake, so you may want to take a camera with you. If you have your cell phone, you will get reception, although weak, at parts of the trail including the starting point at the parking lot. The crater is about 20 minutes from Lee Vining if you are driving and about 3 hours if you are hiking. But if you are hiking, save enough energy to hike the crater and then hike back! Again, it could get hot.

Rim and Plug Trails

The best way to study geology is to explore the earth, and climb around on its landforms. For a lesson in volcanology, we visited Panum Crater, a textbook example of a complete plug dome volcano, located near the south shore of Mono Lake. The volcano erupted in the 14th century, and consists of a central lava dome surrounded by an intact ring of ejecta. To encouter the geology, we followed two accessible and easy trails, one circumnavigating the rim of the volcano, and the other traversing the crater and plug dome. The undulating, two-mile Rim Trail completely encircles the volcano, follows the crown of the ejecta ring, and includes a magnificent panoramic view of Mono Lake. Since the trail surface consists of loose sand- and gravel-sized rock blown out of the volcanic crater, the footing is soft and sluggish, like along the crest of a sand dune.The high point of the Rim Trail is at the north end, where a 180-degree vista of Mono Lake unfolds. The shorter Plug Trail ascends the lava dome in the center of the volcano. The lava dome consists of huge mounds of black volcanic glass (obsidian) and airy beige pumice. Much of the obsidian and pumice are banded together as the frothy pumice floated atop the rapidly cooling lava, like the foam on a pint of Guiness stout. Thirsty for knowledge, we found Panum Crater an enlightening chapter in the textbook of geologic wonders of eastern California. In my book, it gets 4 stars for its out-of-this-world scenery, birds-eye view, stimulating trails, and textbook geology.

A 5 star worthy hike! To get to the trailhead, drive all the way to end of Lundy Lake. There,…read moreyou'll see a small dirt road. Take that all the way to the parking lot at the end. The actual beginning of the trailhead begins just up from the outhouse. After a short distance, you'll come to a fork. You can go straight (which I recommend) and after a 30 second walk you'll reach what I dubbed as, "Lundy Pond". You'll get a commanding 360 view from the beach. Hard to beat. When you're finished taking in the view, head back to the fork and take the main trail that leads to Lundy Canyon. This isn't a difficult hike as some would have you believe. As long as you're in decent shape and have just a bit of hiking experience, you'll do fine. I've seen everyone from small children to elderly folks on this trail. Be sure to take this trail all the way to the Cascades. It was simply gorgeous and worth the extra effort. All told, I did about 6 miles round trip. Highly recommended.

Visited 10/10/21 and WOW! If you want a nice, peaceful hike this is a great spot. It's not as well…read moreknown as Mammoth, Rock Creek, Little Lakes valley, etc, so you won't have to deal with crowds, but it's still a beautiful hike that's just 5 miles off the 395. The road starts off paved and becomes dirt. Some parts look intimidating but it's very do-able in a 2WD sedan as long as it hasn't had heavy rains or snow. I have a 2WD SUV and made it just fine....just drive slow as there are rocks and dips. The fall colors are amazing here!

20 Lakes Basin Loop

20 Lakes Basin Loop

We didn't see 20 lakes in the basin but enjoying nine peaceful mountain lakes during a single day…read morehike was darn fabulous. Located outside the eastern entrance to Yosemite National Park, 2.5 miles of dirt road is crossed to reach the trailhead at the closed Saddlebag Lake Resort at 10087 Saddlebag Lake Road. As a former resort, the location has lots of parking but since the closed buildings meant no running water and an outhouse toilet. The often-closed Tioga Road (aka Hwy 120) must be open to get to Saddlebag. For a longer and harder hike, the basin loop can be reached by going up Lundy Canyon located north of Lee Vining and might be an alternative starting point if Tioga is closed. The loop can begin by heading left across the dam, but we went right around eastern side of Saddlebag Lake - the largest and only man-made lake of the hike. The western side is rocky talus while the eastern trail around Saddlebag Lake is longer but has a more comfortable walking surface that was preferred by people fishing in the lake. The remaining lakes appear at regular half-mile intervals with each having their own flavor. The first set of lakes were small and serene Hummingbird Lake, deep and eerie Odell Lake, and classically graceful Lake Helen. We then took a worthwhile and brief side trip down to Lundy Canyon to the cascading Lundy Canyon Falls. We resumed on the loop to see our favorite Shamrock Lake with multiple little peninsulas poking into the lake which was followed by narrow inlet-like Excelsior Lake, cliff-sided Steelhead Lake below the Sphinx-ish Shepherd Crest, unremarkable Wasco Lake, and meadowy Greenstone Lake before returning along the opposite side of Saddlebag Lake. Maps showed two trails between Steelhead and Wasco Lakes. The western trail is incomplete but also led to the best geology with bold green layered rocks. Our hike was 9.3 miles to circle around nine lakes and one waterfall. The elevation varied from 9,900' to 10,400'. Never steep, the terrain rolled up and down which felt like a 1000' elevation change hike. The paths were mostly exposed with few trees. Located in a true basin, the lakes were surrounded by peaks and ridges. Icy snow pockets that survived the summer ensured water flow through the creeks and lakes.

Hiked this as an overnight backpacking trip with 2 friends in late July, it was the most beautiful…read moreamazing hike I've done and seen in a very long time. Drove up from San Diego the night before and tried to get a camping spot at ~7K feet altitude to get adjusted but all the campsites were full, so ended up camping overnight at disbursed camping down the road (still up at altitude, just no facilities and no fires allowed). Woke up in the morning and made a quick stop at Whoa Nellie Deli to use the bathroom, fill up on water etc. And then drove the very rocky road up to the trailhead. I have a Subaru Impreza, all wheel drive but not a lot of lift, so it was doable, but would have definitely felt better in an SUV, although I also saw a Prius in the parking lot so any car can make it I guess. Parked in the parking lot, there are bear boxes there to leave everything from your car that you're not bringing with you on your backs (also bring a bear canister if you're doing overnight!). Then we headed out. We hiked around the north side of Saddlebag lake, which was beautiful, and a little more crowded as a lot of day hikers just hike that lake. We then took the turn off to the right to head up to the rest of the lakes. On day 1 we did about 6 1/2 miles. We kept passing beautiful lake after beautiful lake. There was a point where we were hiking down a pretty steep climb and it started hailing on us! I was relieved we were hiking down at that point and not up with our packs on. I'd recommend having alltrails map downloaded as there are literally no trail markers, there would have been really know what to know which way to go without it. So we kept hiking and climbing, up and down, around more and more lakes. And then we setup camp for the night around Greenstone Lake. Night 1 was Friday night and was very quiet, no other over-nighters around. Night 2 was a Saturday, and it got a bit more crowded. Nothing too crazy, but there were definitely others in sight and ear-shot. We setup for 2 nights, and then did a day hike the next morning up to Conness Lake which was actually possibly the most beautiful lake I've ever seen in my entire life. I even went swimming in the freezing water! On our last day we woke up in the morning, packed up, and hiked out the remaining 3ish miles back around the bottom of Saddlebag Lake.

While the visitor center is opened seasonally, they have restrooms in front that remain open year-round and have been clean and well stocked every time I've visited. I believe they close overnight--so please check first. The visitor center has a beautiful gift shop, a ranger desk where you can get all your local exploring and curiosity questions answered, a kids coloring table, places to sit, a film, and natural history exhibits. There is also a vast and beautiful back patio space which provides ample viewing options of Mono Lake, the tufa, and the surrounding mountains and hills. There is a nature trail you can follow with better views of the lake. Cell service is spotty in this area, but there are a few spots in the parking lot where the service comes through. I have really enjoyed visiting here during different times of year. Every time I do, I learn something new from the volunteers and staff... They have always been able to help me identify a new animal I've spotted or give me "insider" information about a new adventure worthy of embarking on.

Mono Basin is such a beautiful and unique area to explore. There's an easy walking path that takes…read moreyou right to the lake, making it accessible and enjoyable.
