Hello, forum! Looks like my husband and I are coming back to Yosemite for our FIFTH year in a row--hurray!
I know that similar questions have been asked on the forum about this route, but I'm mainly wondering about elevation/strenuousness because I stink at reading topo maps.
So here's the siutation: We scored Half Dome permits for 9/2 and a reservation at Sunrise High Sierra Camp on 9/1.
The plan is to drop the car to the Valley the morning of 9/1 and take the Hiker's Shuttle to Tuolumne, arriving around 10:30am. Hike to Sunrise HSC (reservation secured) via Cathedral Lakes.
9/2: Hike to Half Dome and continue on to the Valley. Stay at the Lodge (reservation secured).
I estimate this to be about 20 or 22 miles, at the elevation to be about +2,200 and -6,700. We'd cover about 7 miles the first day and about 15 the next. In terms of strenuousness, where would you rank this on a scale of 1 to 10?
For comparison, we day hiked Gunsight Pass to Sperry Chalet (14.5 miles, +2,200ft) and Highline to Swiftcurrent (16 miles, mostly descending, with two passes) two years ago in Glacier National Park. We've day hiked Clouds Rest. Last year we did 20 miles up and back to Thousand Island Lakes from Red's Meadow in two days with packs. So is this itinerary any crazier than those hikes?
Is it really any crazier than hiking round trip from Happy Isles?
Thanks, as always, for your valuable input.
