Backpacking the Yellow Pine Trail, UintasThe Yellow Pine Trail is one of the first trailheads you will pass after entering the Mirror Lake Highway, coming from Kamas, UT. The trail leads to three lakes – lower & upper Yellow Pine Lakes, as well as Castle Lake. You can also day hike to Duke & Castle Peak, both over 10,000 ft. This is a great early-season backpacking route when the higher Uintas is covered in snow. The trail is mostly well shaded and offers plenty of water along the way for your pup to drink from or to filter from. It is slightly steep and rocky in sections, so this trail took longer to reach the lakes than anticipated. The best time to hike here is late June though October, or when the first snow flies.
From Kamas, Utah drive East along the Mirror Lake Highway for 6.2 miles, and turn left at the brown sign for the Yellow Pine TH. The trail starts in the NE corner of the dirt parking lot. There is one port-a-potty.
Here's a driving map.

On the log is carved "YL – CL" – Yellow Lake is to the left, Castle Lake to the right. Backpacking the Yellow Pine Trail, UintasThere was so much water from our amazing Winter that the trail was fully covered by water. We found a little log to cross to keep dry.Backpacking the Yellow Pine Trail, UintasFinally the views open up and you can see pretty far South.Backpacking the Yellow Pine Trail, UintasFinally you will first reach Lower Yellow Pine Lake – a great fishing spot!Backpacking the Yellow Pine Trail, UintasFind the small trail split marked by a cairn to hike up another 5 minutes to Upper Yellow Pine Lake. Ahh, home for the next 3 nights!
Backpacking the Yellow Pine Trail, UintasFor dinner, I've gotten away from always eating Mountain House meals, and now buy $2 boxed Mac & cheese (I've even found them on sale for $0.99 before at Smiths!). It saves me about $8 from the normal $10 dehydrated Mac & cheese, plus tastes just as good and takes way less time to cook. I ate this for 2 out of the 3 nights while backpacking this trip. I bring my own Tupperware to mix the noodles and cheese and as well, and the Tupperware weighs almost nothing. I then clean it and use for my oatmeal in the mornings.
Day 2
Backpacking the Yellow Pine Trail, UintasDay 2 we decided to take a short hike and bag Duke Peak (10,605 ft). We hiked over to the small saddle, then just followed the ridge up. This is looking down to Upper Yellow Pine Lake.Backpacking the Yellow Pine Trail, UintasWorking our way along the ridge – Upper & Lower Yellow Pine Lakes are below us.
Backpacking the Yellow Pine Trail, UintasWe found a lot of snow at the top, but nothing that slowed us down. In fact it was pretty fun to boot ski!

Day 3
Backpacking the Yellow Pine Trail, UintasOn Day 3 we wanted to hike over to Castle Lake & Peak. We hiked back to the trail split, then up towards the lake. The trail gets really steep for about 1/4 mile.

Backpacking the Yellow Pine Trail, UintasCharlie was stoked to find snow near the lake to run through! It was pretty easy to hike to the lake even with the snow, I just kept track on my Gaia GPS app.
Backpacking the Yellow Pine Trail, UintasFinally, we made it to Castle Lake. Charlie loves swimming after sticks – the bigger the stick or log, the better.Backpacking the Yellow Pine Trail, UintasThe water was so clear! This would be a great fishing spot. If you wanted a much shorter hike to get here, you can actually drive up the Upper Setting dirt road (not suitable for small cars), then hike about 1/2 mile to here. From here, we eyed Castle Peak (just above my head to the left), took a quick break, then continued on.
Backpacking the Yellow Pine Trail, UintasWe aimed for the small saddle below Castle Peak, then found ourselves at the base of the peak with a boulder field.

Castle Peak is a little lower than Duke Peak at 10,234 ft. The mountains in the distance are the backside of the Wasatch, and that canyon is Provo Canyon. What a great view!

We then hiked back to camp. Total mileage from camp was about 5.5 miles RT. Perfect for a half day!Backpacking the Yellow Pine Trail, UintasThe "what happens at camp after a day of hiking" photo. Charlie is 70 lbs but that doesn't stop him from being a lap dog! He just needs two laps.
Day 4
Backpacking the Yellow Pine Trail, UintasTime to head home! What a great trip – I was worried I would be bored at this lake since the day hikes were so short. But I was totally wrong – there is so much to explore in just this small area and we had a great time by the campfire at night. I would definitely go here again!
