Doable in a very long day, as it turns out, and great for trail running. Road is very well graded, and there are barely even potholes. I was worried the trailhead would just be a “park alongside the road” type, but there is an actual lot with a pit toilet.
The first five miles are along a soft dirt trail, and very flat. You get glimpses of the river and peaks around you, but don’t begin to gain elevation until you’ve crossed the first bridge (with the wooden hand rail). Just after that, you head up a talus slope. Go straight for a few feet until the trail becomes obvious again, there’s a cairn to lead you just in case. Then you cut back into the woods, and eventually there’s a second bridge (the one with the wire hand rail). The next few miles up to Jade Lake are steeper and we hiked most of that section.
Jade Lake is the first lake you run into, and it’s beautiful. Most parties we met were camping there. There are several other lakes in the area especially if you’re willing to look around a bit (Opal, Emerald, Iiswoot), but we kept heading straight to the basin below La Bohn Gap. We were surprised to find a cabin/shanty just past Jade Lake, which was neat!
The basin is where it gets tricky. There were almost no cairns leading us anywhere (which was better than cairns everywhere leading nowhere, which is what we had been told to expect). Looking up at the basin, you head up and then cut left as soon as you’ve gotten above a rocky/vegetated outcropping. Basically, keep to the left along the trees until a climbers’ path becomes apparent, and then follow that to La Bohn Gap. We have a woman to thank, who appeared at the perfect time. While we were deliberating just how far left to aim, she emerged up to the left across the boulder field, on her way down from the lakes!
La Bohn Gap was amazing. I was floored. It’s easily one of the most beautiful places I’ve been in Washington. The lakes were stunning, comparable to the enchantments according to my running buddy. You come up to a ridge and suddenly the first lake is laid out beneath you sparkling in the sun and there is no noise besides you and wind and streams. We took a bunch of pictures, marveling at how clear the lakes were, and the rocky alpine ridges surrounding us. There is no snow at the lakes. In fact, there’s barely any snow on Hinman at all.
To get up to the ridgeline that takes you to Hinman, ascend the boulder field east of La Bohn Lakes. We cut between the two largest lakes and picked our own path up the slope, which meant more boulder hopping and light scrambling. Once along the ridge, the true summit is in view (the set of jagged, blackish vertical spires) and the ridge is easy to follow. Bear’s Breast and Summit Chief look amazing, and you can see several lakes in every direction. The ridgeline is also completely snow free, for better or for worse. It means lots of boulder hopping. The rocks are pretty solid at first, but the blackish rocks near the summit are much looser. We hiked this part on the way up and then ran (okay, my buddy ran, I was doing more of an expedited boulder hop process) back down the ridge, which was gradual enough to be manageable. The true summit I think is technically the easternmost edge of the rocky spires, but I’d just count that whole section.
Going back to La Bohn Gap we again just chose the path of least resistance. The return trip was quick since downhill is always more runnable than uphill. We didn’t pass anyone else aiming for Hinman, but the whole area is like a playground for adults. Necklace Valley, lakes, La Bohn Gap/Lakes, Chain Lakes, Tank Lakes, Iron Cap, Daniel… there is a ton to do up there from a single base camp if you have the time. And the hike had everything. Waterfalls, ridgelines, forest, rivers, lakes, peaks.
23 miles round trip, around 7000ft elevation gain (net). Took us just under 9 hours up and down including our breaks and the eight hundred stops I made us take so I could get photos. Enjoy!
**also, correct me if I'm wrong about peak names in the first picture
