This is a 12.4 mile out and back hike to Ostrander Lake with about 1617 ft. of elevation gain, from 7000 ft to over 8600 ft. The trail head is located off Glacier Point Road. The first 3 miles of the hike are relatively flat. The next 3 miles climb at about a 10% grade. The mountain crests at about 5 and 3/4 miles, then drops down to Ostrander Lake (8505 ft).

Nice and flat first 3 miles with a steady incline the last half of the trail. Beautiful lake worth seeing.

Nice and easy backpacking trip. Camping by the lake and swimming there at sunset made our stay perfect. You should expect moderate solitude only, lots of mosquitoes, and maybe you will see a bear as we did after only 20min on the trail!

In the end of June 2017 I did 3-day backpacking tour to Ostrander Lake. Trail description is pretty good. Trail is well marked almost everywhere by regular rusty posts and ski-markers. About half mile before the lake it forks several times for vista points or something similar, but in general it is easy to find the right way. This was a 1st time when I meet bear in Yosemite on trail in about 2 miles from parking lot. It was black bear, it was scared by hikers and run away in the forest, then showed up again on trail and walked in opposite direction. Unfortunately, there is no trail beyond the lake. it could be interesting to walk along the creek to the upper lakes or climb to the top of Horse Ridge.

Did this as a weekend backpacking trip two weeks ago with a couple of buddies. Like everyone has said, the first half of the hike is fairly flat with very little elevation gained. Within the first hour of the hike we came upon a nice 7-point buck and a decent sized black bear less than 10yards from the trail.
The second half of the hike is a bit strenuous, but nothing ridiculous. It is a steady incline that is easily conquered; with 40-50+lb packs we still managed to make the lake in just under 2.5hrs. The majority of the established campsites and fire rings lie along the Northwest shore of the lake.
The next morning we climbed up to Horse Ridge, which was a short Class 2 scramble. We then traversed the ridgeline and dropped back down near Hart Lakes. From Horse Ridge you get an amazing view of Half Dome off in the distance.
Over the course of the weekend we had day-hikers trickle in and out, but by 3 or 4 they’d be gone. There was three or four other groups camping at the lake with us, but never once were we bothered by the company.
I would highly recommend this trail to novice backpackers, and to those looking to avoid the hordes of people that flock to Glacier Point.
