Sierra Point is a viewpoint on the eastern end of Yosemite Valley from which you can see four waterfalls: Yosemite Falls, Illilouette Falls, Vernal Falls, and Nevada Falls. This old map shows a trail to Sierra Point from Happy Isles (look between Happy Isles and Grizzly Peak). However, this trail was closed back in the 1970s due to rock slides.
It is still possible to hike to Sierra Point but it is not a nice and easy trail like the others you’ll find out of Yosemite Valley. I personally found the route pretty straightforward and easy using detailed instructions and GPS waypoints given to me by a friend (and readily available via some googling), but I hate to gauge difficulty since it is so subjective. People inexperienced with off-trail travel (especially on steep terrain) and routefinding might find this to be very difficult. So the typical caveat applies: Only you know your skills, comfort level, and abilities so it is up to you to make the call when out there.
Sierra Point juts out about half way up the wall between Grizzly Peak and the John Muir trail. The point is visible from parts of the JMT but very few people know to look for it. I felt like I was a super secret spy as I stepped off the main trail and picked my way through the pile of talus. Before long we found the old trail and as we climbed we heard the voices of the hikers on the nearby JMT, a mere few hundred feet away as the crow flies.
The old trail still exists, and although it is overgrown and taken out by rockslide in a couple of places it is pretty easy to follow. The hardest part is actually finding the old trail. From the ‘Rock Slides’ sign about 500 feet from the Happy Isles Bridge, climb through the talus for about 200 feet. The terrain kind of naturally popped me out where the old trail is evident, but I wasn’t 100% convinced until I saw some constructed steps jutting through the fallen leaves of the forest floor.
The trail climbs steeply. There are a couple of places where it seems to fade away or requires scrambling up a short stretch of rock, but it was always easy to find the way. I recorded the track below on the hike – unfortunately it is not entirely accurate due to the bouncing around of the GPS signal when so close to the granite walls of Yosemite Valley. About .7 miles and 1000 feet up, the trail rounds a bend a pops out on a pile of granite jutting out from the side of the cliff.
The view from Sierra Point is worth the effort! There is nothing like seeing the classic Yosemite sights from a different angle. From here you look down on Vernal and Nevada Falls, Illilouette across the way, and Yosemite Falls across the Valley. Best of all, we had it to ourselves. Although the voices of the hikers below carried up to us, we sat there by ourselves for a while, thoroughly enjoying the feeling that Yosemite was all ours.
