R02 TR: Hetch Hetchy: Tiltill Valley and Lake Vernon, May 2023
Posted: Thu Jun 01, 2023 1:29 pm
I've gotten lots of inspiration and information from this board, so I felt it's time to give back and write a trip report.
Routes:
Hetch Hetchy TH to Tiltill Valley via Rancheria Falls on May 13-14, 2023
Hetch Hetchy TH to Lake Vernon via Beehive Meadow on May 27-29, 2023
Snow and water conditions:
The entire trail to Tiltill Valley was snow free. Crossing Tueeulala Falls Creek was easy, did not even get my feet wet. Wapama Falls was flowing over the bridge just a tiny bit. I got soaked from all the spray, but that was welcome in the sun. Tiltill Valley was flooded, up to my knees for a few hundred feet. There was no snow on the South facing slopes up to 2400 m, North facing granite slopes up to 2000 m.
Two weeks later, even though there was less snow in the mountains by now and even though the weather was cooler, the creek levels had gone up quite a bit. Crossing Tueeulala Falls Creek was over knee deep, but crossable with caution, flowing briskly. The bridge at Wapama Falls was partially flooded, but we heard people had crossed it.
The trail to Lake Vernon was covered in up to 5 ft of snow starting shortly after Beehive Meadow. So the snow line that I observed two weeks prior on exposed slopes does not quite apply to forested valleys. Some transitions from snow banks to gently flowing water, but with careful balancing on logs, we made it without getting our feet wet. After the pass, going down into Lake Vernon basin, there is no more snow on the trail and barely any in the basin. I brought microspikes, but did not use them. Hiking poles were useful as always.
The bridge across Falls Creek right below Lake Vernon was not flooded, but it would require waist deep wading in slowly flowing very cold water to get to the bridge.
Campsites:
I found a beautiful campsite on the Northern end of Tiltill Valley. I had the entire valley to myself. There were 5 to 10 tents near Rancheria Falls (within a mile from the reservoir), but nobody else stayed up in Tiltill Valley.
Near Lake Vernon, we found a beautiful campsite on the slabs about 30 min before the lake, with great views and our own little snow melt creek.
Bears:
Briefly after I set up camp in Tiltill Valley, three bears entered the meadow below my campsite, about 500 to 1500 ft away from me. I watched them for about three hours until it got dark. They came out again the next morning. Pretty big, pretty black. I don't have photos, because I did not bring a tele lens. It inspired me to equip my phone with a 10x25 lens. Together with a 3d-printed adapter, this setup costs about 9 $ and weighs under 70 g. Image quality is better than without the lens or with the naked eye, but obviously could be better.
We saw a Mama bear with three tiny cubs near the snow survey shelter at Lake Vernon, which kept us from going to check out the waterfalls coming down from Branigan Lake, which were quite impressive.
The bears did not mess with our canisters.
Permits:
I was lucky and had made advanced reservations for permits. Still, it took 40 to 70 minutes to have them issued at the Hetch Hetchy gate. Pretty lengthy process. Probably best to arrive early. The gate opens at 7. I heard that all walkup permits were taken, but many unclaimed reservations were released at 11:00. I guess people did not show up because of snow conditions. Interestingly, we saw only a handful other parties at Lake Vernon (despite Memorial Day weekend, despite most other trailheads being closed) and none anywhere near our campsite.
Have a good time out there!
