Took me three hours and twenty seven minutes from the 2WD parking area but I missed Lewiston Peak on the way up and bushwhacked to the col between the two mountains instead. If you attain the ridge and summit Lewiston first you should avoid the posted private property signs lower in the forest on the southern slope. It started raining as I summited and views were limited, but the summit register has a new notepad.
Received permission to hike any day between 7/18 and 7/24. Following a wear path we missed a turn and stayed on the wrong path for a while until I was confident the trail wouldn't correct to where I expected to be. Turned around and found the correct trail and happily ended up on top of Flat Top, touching Lewiston along the way. Saw one other pair of hikers near the top. 4wd and high clearance could get you to a 5 or 6 mile round trip hike, our 2WD Rental sedan didn't get far... adding in the wrong turns we hiked over 12 miles. The road gets pretty serious, so don't assume any 4wd will get you as far as is possible to go.
Went up the road to the saddle at 8000 feet, then followed the trail to the saddle at 9000 feet. Instead of going to the left or right, I went directly up the ridge since it seemed the least likely to contain snow. Went pretty well, though there was a small section I was going through powder halfway up my knee, then coming off Lewiston there was powder all the way up my knee. Then it was back to the random snow drifts and rocks. The views from the top are hard to beat, the entire Wasatch is visible, so are the Uintas, Ibapah Peak, and other various peaks in the vicinity
Possibly helpful info:
Past Ophir from end of pavement -
0.7 miles to well-marked turnoff to "trailhead parking." I think this is mostly planned for use by ORVs as there are maps of routes. From the turnoff to the large parking lot it's about 0.6 miles up the road, which is very well graded and I think could be driven by any vehicle that made it to this turnoff.
1.4 to 1.6 miles from end of pavement are camping sites on both sides of the road, well spaced, most near stream, with vault toilets.
2.2 miles from end of pavement to end of drivable road, where road was apparently washed out by the stream. I crossed the stream 10 times on my way up to Picnic Canyon.
There is a trail all the way to the ridge north of Flattop (area marked "corral" on my topo), and then south along the ridge, but I lost it when I got to the final thousand feet up to Flattop, which is fairly steep through brush and fallen trees, making it a pain.
I did a 12.5-mile loop from the campground up Picnic Canyon, along the ridge to Flattop and continuing to Lewiston (easy) then following trail down the ridge to the east until I lost it - I think this may be where there is a switchback to the south, which I didn't expect. So I just headed straight down, easy going at first, then increasing brush until I reached the dirt road from Hall's Basin, which was a pleasant walk in brilliant fall colors and no traffic.
Got permission from the land owner to hike this, was a little disapionted, but not really, its a hot dry desert peak. Glad to have done it. However this is a one and done Kind of place ophir the town before the trail head is actually really cool so maybe I will go back there.
I climbed this with my brother in law from a base camp in Saratoga Springs. Word got around the neighborhood fast that we were going to attempt the mountain and one of his neighbors joined in. It was a nice hike. There was some icy snow left on Lewiston, which made for some slow going.
Someone needs to bring up a new summit log and pen. The one up there has been eaten by mice, but you can still read stuff people wrote in the 90's
#1: 8/4/18: Haze from the summer fires made it more about the hike than the views this time. I parked at the South Fork/Lion Hill Loop parking lot which adds a couple miles (intentionally) and came up via Lewiston Peak. (I emailed Weston Ault but never got a response but didn't see anyone else on the mountain.) Unfortunately, I followed the trail around the south slope after the 9000 ft saddle, lost the trail and just bushwacked up to the 9600 ft clearing. The Lewiston ridges are fun and, Flat Top is actually easier (a little anticlimactic, after Lewiston, actually). Overall, great hike!
#2: 9/23/18: Same route up, except took the north route between 9000 ft saddle and 9600 ft--brief no trespassing area but didn't see anyone and it's a much nicer route than the south route! This was the start of a long day traversing the full Ophir circuit: Up Ophir South Fork to Lewiston & Flat Top, north across 9925 and 9820 to Lowe, over 10160 to Rocky, then over 9530 and back up to Bald, coming down via Serviceberry. 24 mi, 8100 ft elevation gain, 12 hrs 20 mins, including breaks.
(1) Lewiston and Flat Top loop, with Moogie737, yadahzoemtn, Brent and Dave. Beautiful day, ~90% of the hike on excellent firm snow using crampons. (2) 15 May 2021 both peaks w/ Wasatch Mountain Club.
There was bad weather for weeks in WA so Heather and I drove through OR, CA, NV, UT, and ID. We climbed 37 peaks in 19 days and on the 13th day of the trip we did Deseret Peak, Flat Top Mountain and Lewiston Peak. Deseret was a lovely hike similar to Timpanogos but Flat Top was a horrible hike through cattle grazing land with numerous biting flies. trip report
With Sam Jewkes, Jen Richards, Tara Summers and Leslie Howlett. The approach is a total schwack, but I loved this remote peak with incredible views from the summit.
The views from the top are magnificent. Beautiful fall day. Best of Best company.
#1. 10-14-14. Quite the summit. Could not find a survey marker but found a silver mailbox and the oft-mentioned solar panel leftovers. My GPS showed a distance of 1.17 miles from Lewiston Pk. IVD. Jambo. #2 11-08-14. Again from Lewiston. Tolle Gesellschaft! #3 3-18-16 W/Brent. First winter ascent of the Oquirrhs highpoint. Halls Basin to a gnarly ridge up to the ridge between Lewiston and Flat Top. Micro-spikes all the way up, SS down off the main ridge. 5+31 up, 3+24 down. R/T 8.44 miles. Had to park on the main road below the normal TH. #4 3-17-17 W/ Signe. From Lewiston Pk (via east ridge) and descent down the big broad basin into Pole Canyon. Snowshoes down to 6,500' on the road. #5 4-21-17 W/ Jim, Brent, Lana & Dave. After Lewiston. Excellent snow for crampons above 8,200'. Never used snowshoes. Descended from the notch between Lewiston & Flattop.
Went up in the evening after work for a hike in the moonlight. a bit cold in the wind on the ridge but worth it.
Climbed from bottom of South Fork Road to Lewiston, then over to Flat Top, and also to peak 10340 (East Flat Top). One of my favorite mountains!
Started at the trailhead and bagged Lewiston as well. 11 Mile RT in 6 hours 45 minutes with 4,027 ft. of gain. Only had to deal with a few snow drifts on the North side of Lewiston. The route finding was surprisingly easy. Great view too!
Drove to the saddle, then took the left fork of the trail, which I lost in the slushy woods. Went straight up the open slope north of the forest, then down the right fork of the trail from the ridge. Trip report.
2/5/2015 Second time up. Hiked up with James Barlow. Fun winter ascent.
11/10/2013 Hiked up from the new trailhead area, to Lewiston Peak, and onto Flat Top. First time hiking in the Oquirrhs, great hike.
