I did this trail clockwise with a friend over 4 nights, 3 days plus we added our first night at Laurel Lake. Being pretty fit ourselves, we found this to be a challenging trip and very sunny/warm. Sometimes water stops are not frequent so be sure to carry plenty of water! Several boggy spots where you will get quite muddy/dirty: headed into Laurel area, headed up after Vernon Lake, Tiltill area. Heading into Laurel area you will also have to cross a river to about the knees. Bear tracks and sightings, be very careful and aware of your surroundings at all times! Many downed trees and overgrown paths so be sure to have GPS or maps to avoid getting lost. Overall very beautiful and a wide array of scenery as you hike along.

We did this trip over Memorial Day weekend so we saw a good deal of people. Overall, this was a nice 2 night, 3 day backpacking trip. You get to see quite a few different landscapes and get a pretty good workout overall. Day 1 and 2 is about 10 miles with day 3 around 6.5. There's some good climbs but overall, not to bad. Be prepared for some bugs in TilTill and possibly flooding in the valley. Be on the look out for bears too in the Beehive area. Both locations have sites with fire rings. I'd recommend this for anyone looking for a fun, moderate 3 day backpacking trip. Remember Leave No Trace!

clockwise May 19 2018, 3 days 2 nights. Camped at Vernon lake and Rancheria (considered Tiltill but limited sites and unlimited mosquitoes).

In the early season, this is as good as any Yosemite backcountry hike (lakes, waterfalls, views, variety of ecosystems and vegetation)
+ and
no crowding (walked up for permit, saw fewer than 10 people when away from lower trail along the reservoir).

In later season I can imagine the dust and heat and aridity might change the balance and drop a star.

It may distract from your enjoyment if you think about the history of Hetch Hetchy reservoir. Consider the info from online and national park service as well as from San Francisco department of water that is on the placards.

Prep suggestions:
* we liked clockwise, not only to get elevation out of the way early, but facing into nice view coming back down to Hetch Hetchy :
* be ready for wearying uphill and downhill out of and then back in to Hetch Hetchy Valley
* check if you will need to wade thru Tiltill Valley (water above boot line and no way around, for approx 20 yards each side of the valley). Soft soil and grass meant barefoot was fine for most of our group.
* fair amount of bogs and rock hopping and downed trees changed our time calculus.

Highlights:
* great campsites + no fire restriction
* water at Wapama falls is enough to get wet walking across the bridge but not enough to close the trail
* wildflowers!! (So so many and so many species, especially at lower elevations)
* Tiltill Valley = spectacular in a peaceful way, well worth seeing (think baby Yosemite or tiny pre flood Hetch Hetchy)
* Vernon lake, especially from the ridge above the lake (toward Tiltill/Rancheria)

Note on mileage: Trails illustrated is 25, not counting unavoidable .5 each way from parking to the dam and variable to get from junction to actual camping at Vernon (.3 each way, but could be more). My gps said 27.5. I would use 25+ for planning assumption, not the 23 from AllTrails (sorry guys!)
Final note that the backcountry office says 28 miles, but I believe that is the trails illustrated 25 plus 3 miles optional extra around laurel lake.

Good early season trip. It was clear the trail crew hadn’t made their rounds...many down trees and overgrown sections.

Did the loop counterclockwise staying at Vernon night one. Very pretty lake with better campsites in the eastern side.

Lingering snow near Mt Gibson. Tiltill Valley is beautiful but bogged out requiring forging the meadow through calf deep water which was much funnier in the car ride home than it was while we were doing it.

The trail from Tiltil Valley to Rancheria Falls is pretty exposed and overgrown. All the sites at Rancheria we’re either taken or to too close for comfort so we ended up heading for the car.

The bridges at Wapama Falls were fun to cross and a nice mid-day soaking.

This was my first experience in Yosemite, and we chose this trail because we'd heard there was less traffic and we were looking for true wilderness and not many people. We'd originally planned to go up on Moraine Ridge and down into the Jack Main Canyon, but because of the still high levels of snow there in mid-to-late June, the rangers recommended against it. They also warned that we may not be able to cross Falls Creek because of the amount of snowmelt. The switchbacks were hard and gruelling in 90 degree heat, but I made it and am proud of that (at 58 and not backpacking in almost 40 years, that is saying something). We hiked toward Beehive Meadow which was nothing but mosquito-filled because of all the wetness on the trail. But arriving at Lake Vernon, we were thrilled. The granite surrounding the area, the lovely lake, the camping areas, the side trails, the wildflowers, the wildlife... all quite wonderful. I fell in love with this backcountry, for sure. So beautiful, so peaceful. We were not able to make the loop because of the raging water covering the footbridge at Falls Creek, but we spent a couple nights here before heading back down. I definitely want to do this trail again, but go onto the Ridge and the Canyon too, in a season and year when the snows aren't so prolific.

Actually, my review pertains to the Lake Vernon Leg, only, done in September '71, and August '72. There are a few terraces, past the Lake Eleanor Service Road portion, commencing at about the 4,200 Ft. elevation, that comprise PURE, to nearly pure Ponderosa Pine, with Jeffrey Pine, and Jeffrey/Ponderosa Pine hybrids, until about at the top of this stretch at Beehive Junction (Left Trail eventually to Bond Pass, out of The Park; with the Right Trail being the fairly level 1.5-2 Mile Inrun, to Lake Vernon.), with elegant Red Fir, too. If, you are a Dendrologist, or know someone who is, I'd STRONGLY advise you to be directed to this more or less contiguous big grove of these species, to record NEW CHAMPIONS of these! Many have assumed the appearance of Sequoias, they are THAT giant! Huge buttresses at their bases; Diameter Breast Heights of at least 8 Feet; Total Heights MORE than 220 Ft.--I'd guess; negligible Taper, up to about 120 Ft.; with the first HUGE limbs occurring at about 80 Ft. And those limbs could be trees in their own right, at about 3-4 Ft. diameter! Granted, there may be some Sugar Pine and White Fir giants mixed in here and there, but it's the Ponderosas and Jeffreys that most definitely COMMAND your attention, with their metallic-looking alligator hide-patterned Barks, and tiers upon pagoda tiers of Limbs, ending in the glossy candelabras of long, thick foliage. At Beehive, and towards the Lake's East end, you will find some handsome strapping Quaking Aspens too, if I recall correctly. Also, at the Inrun stretch of trail, there is a vast field of level to gently sloping glacially polished Granite, polished so heavily (with a few boulder erratics), that it's like tombstones or kitchen countertops, and if the sun hits it just right, you can not look directly at it--absolutely blinding. Soon after exiting the Dam Tunnel, you will encounter highly anomalous Pinon Pines, mixed in with the Digger Pines, and a few Knobcone Pines. The reason for that, is that Hetch Hetchy was along a prime Trade Route, between the more localized Miwok peoples, and the mostly East-Slope peoples of the Monos, Bannocks, Paiutes, Shoshones, and other tribes, where the Pinons more naturally grew. Either a few seeds sifted out of their baskets, or the Miwoks/Ahwhaneechees tried to plant their own groves, so that they wouldn't have to depend upon the Easterners. These sights and more, will make for one heckuva unforgettable experience that you will ALWAYS treasure!

This trail was not my favorite. It felt grueling and very hot, with little pay off. The lake access is limited due to vegetation. However, the granite surrounding scenery was pretty impressive. It wasn't recommended by the rangers to cross Falls Creek because the water level is much higher than normal, therefore we could not complete the entire loop. That may have changed my rating. Going to just Lake Vernon and back from Hetch Hetchy was not worth the heat and work.

headed out from the dam to do a loop around Hetch Hetchy area..lots of elevation going up to Lake Vernon and Laurel Lakes, but well worth it. Many campsites around Vernon, some have cliffs to jump off, others have soft mud but clear water. Views are great, so many peaks to look at..the descent to Tilltill and Rancheria was fun, lots of running down hill, only saw 5 people in 3 days..once we arrived at camp near the Falls, we explored the pools and waterfall and cliffs, great place.

In the spring this is my favorite place.
-Till Till Valley:
-Water logged in spring so bring your water shoes.
- Bears either live here or frequent this area in early spring so be mindful of them.
- Two camp sites that I've seen offer a place to rest before you continue on to Lake Vernon.

Lake Vernon:
- Beautiful granite encased lake.
- Camp sites on both sides of the lake
- Bears are here in the spring. (watch out for Jack, he likes too steal your food)
-Good fishing for you anglers. (caught a beautiful 3-4 lbs rainbow trout.)
- Water is Crystal clear and very cold.

If you made it to Rancheria falls and didn't want to die you are in good shape. Why not continue to Till till valley? It's only a short hump over a mountain!
If you love the Sierra Nevada mountains like I do then it's worth every step.
The novice hiker or backpacker may want to overnight at the Rancheria falls camp ground and either day hike up or just move camp to till till. (only a couple camp sites at till till)
In the spring the valley is ringed with or sometimes completely flooded with about shin deep water so bring your water shoes
