The road from CR 41 to the trailhead is still closed, which adds a couple miles to the hike. There was still plenty of snow to go around, though it was nice wet snow which made it easy to snowshoe or even hike through. I wasn't able to make it up to Kelly Lake and instead took a detour to Jewel Lake. It took me about half a day to make it up there. The views were definitely worth it, although not enough snow has melted for Jewel Lake to actually show. I will definitely be returning come summer to conquer Kelly Lake!

Was lucky enough to have the Clark Peak Yurt reserved for labor day weekend 2019, so access to the trail wasn’t a huge issue. As the other comments mentioned, this hike is no joke, but Kelly Lake is gorgeous and worth it. Be ready for incline and scrambling, and don’t forget to go down to the lake itself (though the overlook is also beautiful). Lastly, there was still some snow on this trail, but it wasn’t a predominant obstacle when compared to the incline (which, luckily, is mostly in the shade). Good luck!

It’s tough to get to the trailhead right now. 4wd with a lift is my recommendation. Difficult but great

When it says difficult, they mean difficult. Not for the faint of heart, but spectacular views. The road up to the trail head is 4X4 road, there is limited parking at trail head & another small parking area a mile & half down from the trail..

First to Review

Did this one on my 45th birthday in Sept 2017. There was 4 inches of fresh snow and it was cold as hades. Beautiful hike that I hope to do again and climb south Rawah from the west side.
