Attempted this loop 5/17-5/19 2018. Parked at Big Meadows trailhead and hiked in to Weaver Lake on 5/17. I was the only one there for the night which was quite nice. There are a number of campsites and fire rings already set up here. Just make sure you get your fire permit from the Hume Lake District ranger station on your way up the mountain. My one complaint about Weaver was that there was a bit of garbage scattered around. My guess is that this is a pretty popular day hike from Big Meadows and so the commitment level is low for a lot of people who stay out there. It wasn't awful but it was indeed noticeable.

5/18 I left Weaver Lake in the morning and headed east toward Rowell Meadow. Right away I noticed that the trail was difficult to follow due to snow on the ground. I had to double back several times to find the trail. I ended up hitting the trail junction and turning south towards JO Pass. The snow on the ground got worse as I climbed and there was a point when I wandered far enough off trail to be lost. Luckily I was able to rediscover the trail after some scrambling before running into another lone hiker heading the opposite way. He informed me that JO pass was still a mile up the trail and that I could follow his footsteps in the snow to get there no problem. I thanked him and we parted ways. Once I hit JO Pass I decided that instead of heading toward Jennie Lake which was my original plan, I was going to descend down the other side of the pass into Sequoia Nat'l Park towards Clover Creek/Twin Lakes area. The ground was completely covered with snow on top of the pass and I did not want to venture towards Jennie Lake without a clear trail. Unfortunately the trail was hard to follow even as I descended the other side. I ended up off track again and I began to follow Clover Creek southward for a few more miles. At night fall I set up camp somewhere alongside Clover Creek.

5/19 woke up early and continued south along Clover Creek toward the Kaweah River Valley. Stumbled out of the woods at Wuksachi Lodge and hitchhiked back to my car at Big Meadows.

I would not do this loop again this early in the season without a solid GPS. Not being able to follow the trail easily due to snow added a fair amount of stress to the trip. Other than that, this is a beautiful area and I look forward to visiting again so that I can actually see Jennie Lake and stop by Rowell Meadow as well as summit Mitchell Peak.
