Arguably the most popular hike in Yosemite Valley is the 4 Mile Trail. In winter, though, there are far fewer hikers willing to brave the conditions to make it to Glacier Point - At least that's is the assumption. I would venture to say we saw about 15 others on the trail during this 6 hour hike.
The trail itself leads to Glacier Point. In warm months, you can actually drive to this lookout from the Valley. In winter, when the snow falls, the road is closed and you're forced to use your feet.
You begin in the Valley and gain about 3,200 feet. This is one of the few hikes where the trail actually faces the valley for most of the hike. And the views are amazing. We are able to see El Capitan and Yosemite Falls until we hit Union Point. This is about the point in the hike when we were in the clouds for the remaining mile to Glacier Point.
The biggest bummer: the view of Half Dome from this location is incredible and we were in the clouds with about 25 yards of visibility. Seriously, google "half dome from glacier point". I guess this just means I'll need to go back to try again.
