Pioneer Basin & Golden Lake via Mono Pass — July 2026

Pioneer Basin is one of the recesses in the Mono Creek canyon and it has been high on my list of places to visit since reading about it years ago. It's a classic Sierra destination given it's accessibility and because of the fact that you can bring dogs. My fiance Ariel and I saved it for the low-snow July 4th year, hoping that the early melt-off would provide us with respite from the mosquitoes, and brought along our pup Atlas. This region is full of different ecosystems: you can bag peaks, explore off-trail basins, swim in alpine lakes, or explore the deep and forested river canyon of Mono Creek. Overall, Ariel and I had a fantastic hike and I would recommend this as a beginner friendly outing with many side-trips that can be explored.

Day 0

Ariel and I drove up with Atlas from LA and spent the night in Bishop. The Mosquito Flat TH is at end of Rock Creek Rd, and we had initially planned to camp along the road at East Fork campground. The area is quite popular given its many campgrounds and the fact that Mosquito Flat TH also provides access to Little Lakes Valley, which is one of the most popular day hikes in all of the Eastern Sierra. We decided at the last minute to switch to a hotel in Bishop so we could get one last shower and went to sleep early anticipating an early morning.

Day 1 - Mosquito Flat Trailhead to Golden Lake

We had a slow morning that started with a small breakfast and coffee. We were clearly a little late the trailhead at 930am given how hard it was to find parking. We parked about a third of a mile from the TH and began our hike, making an official start at 10am. It was hot and this trail is exposed, so we took our time to make sure Atlas did not overheat. The trail is beautiful from the start, filled with small stream crossings and views of Little Lakes Valley below us. Atlas was enjoying the creek where it was shallow and slow and we enjoyed watching him get his water-zoomies. Mosquito Flat is at about ~10,200ft so as soon as we split towards Mono Pass and started gaining some elevation, we could feel it.

Slowly but surely, we made our way up taking a few breaks whenever we could find some shade. The views of Little Lakes Valley got better and better, eventually turning into views of Ruby Lake below and then Mt. Abbot, Dade, and Bear Creek Spire deep in the back.

We took our sweet time, huffing and puffing from such an immediate jump to elevation with zero acclimation and full packs. But after a little more than 2 hours of hiking, we made it to the summit of Mono Pass, and then walked a bit further to Summit Lake where we took some time to sit, relax, and eat some lunch.

During lunch, I struck up a conversation with a guide who was with a large family, seeing if i could get some information on the mosquitos up ahead. That conversation led to her suggesting we head over to Golden Lake via an unmarked turnoff up ahead. Given the amount of crowds we had seen on the hike so far, I liked the idea of base camping somewhere that was off the beaten path a bit and the topo map didnt look too tough for Ariel and Atlas. More importantly, it would only be another 2-3 miles or so and I could tell that I needed to get Ariel into camp sooner rather than later since she was getting a bit tired.

We pressed on from lunch and turned towards the obvious saddle down to Golden Lake and by 3pm we were down at the shores. We found a camp site that we liked, set up the shade structure, and started relaxing. Golden Lake ended up being a fantastic place to camp given that it had multiple flat sites, plenty of running water, no mosquitos, and absolutely excellent views down along the outlet. We spent the night having a few drinks, exploring the outlet barefoot (the grass was 10/10), and swimming in the lake. After about an hour of relaxation, Ariel looked at me, gave me a huge smile and said, "This is fun!" That was all i needed and all the planning and heavy pack was worth it.

Day 2 - Golden Lake to Pioneer Basin and back to Golden Lake

This was our first time using our double sleeping pad and sleeping bag and we both loved it. Both are Big Agnes products: the sleeping bag is the King Solomon which is a 20 degree and down so very lightweight. We were never cold, but realistically it wasn't that cold of a night. We didnt set an alarm but were awake early enough so that I could make us breakfast, coffee, and get going by around 9:30am. It was a beautiful July 4th day and we were off to go lay eyes on Pioneer Basin, a place I've wanted to see for a while. I had a rough goal to summit Stanford North if things aligned, but that was secondary. Priority was enjoying the day with Ariel and Atlas.

The view down the Golden Creek was phenomenal right out of the gate, strewn with wild onions that Atlas and I kept snacking on (although it's not great for Atlas's stomach) and big views down valley, we enjoyed the jaunt down into the Mono Creek canyon. With the change of ecosystems, it felt like it got hotter and dustier. It didn't take long for us to get to the turnoff that leads to Pioneer Basin and from there we made great time into the Basin.

It got beautiful very quickly, but also just as quick did the mosquitoes arrive. To be totally frank, it got terrible much faster than i expected. Even though we were in such a beautiful part of the range, it was hard to enjoy because every time we stopped, we would get stormed. This was not something that Ariel was used to, and it wore on both of our patience level.

It was early in the day and I still had the potential goal of climbing Stanford North, but we needed to find a place where Ariel and Atlas could relax and wait for me to return. We went higher and higher into the basin, thinking that maybe it would give us respite from the bugs, but it did not work out. Although stunningly beautiful, it got to a point where we had to give up since splitting up was not an option in my opinion. I was upset, but I'll certainly be back here.

We were hot, tired, and bitten up by the mosquitoes on the way home. However, the early turn around gave us plenty of time to enjoy the sun and the views at Golden Lake.

Day 3 - Golden Lake back to the car

We got up and out early so that we could get back to the car at a reasonable hour. Since this was a repeat of our hike from Day 1, there wasn't much to note about this hike outside of the fact that Ariel enjoyed going up and out of Golden Lake much more than going down. There was some huffing and puffing as we slogged up to the pass, but then we jaunted down enjoying the absolutely incredible views.

This hike wasn't the longest, the hardest, or the most beautiful, but it was one i'll always remember. There is nothing better than getting out into the mountains with Ariel and Atlas, making memories that we'll have forever. Until next time....
