1. We hiked from the Ahwahnee Hotel on the trail behind the valet's parking lot. This is a dirt trail going around huge boulders, and eventually merging with the bike trail leading to the paved Mirror lake trail.
2. There is a restroom at the junction of these two trails, but the lock on one of the bathrooms didn't lock, so knock before entering!
3. You can also get to the Mirror Lake trail head using the free Valley shuttle stopping at the #17 stop just after the #16 stop at the Mist trail.
4. From the trail head to the Lake is no more than a mile on an very wide paved road. Cars with handicap plates may drive up to edge of the Lake. The paved road has a very gradual upward incline until the last curve before the lake.
5. Here the paved road becomes very steep. Not wheelchair accessible here, but I've seen many a strollers pushed up to the Lake. There is a sign about 200 yards short of Lake, requiring rental bicycles to be stop at the bike rack.
6. At the lake edge is another set of restrooms. There is a sign prohibiting all bicycles and dogs from entering the dirt trail. Walk another 100 yards, and you reach the site where everyone takes pictures of people on top of the square stone at the waters edge.
7. Today, Monday March 17,2014 at 10am, the whole area is in the shade, with little or no reflection from the mountain walls on the lake.
8. We decide to hike around the lake. The hike is pretty easy as it is level. At the half way mark, one will come to a bridge crossing the fast moving stream. Afterwards the trail disintegrates into a watery swampy area, full of fallen trees, before reaching the landslide region.
9. The landslide region is a stark contrast to the surrounding forests. The entire area is filled with huge boulders and stones. However the trail has been cleared of obstacles.
10. Continuing on wards, and you come to the lake again. However you can't cross the lake, as the water is flowing too rapidly in this day in March.
11. We hike completely around the lake to the roadway, and then hike back up to the picture site with the single boulder. By 1pm the setting is in the sun. Everyone crowds around waiting in line to take shots of their friends clowning on the boulder.
12. This year the lake level is definitely shallower than in the past years, when water surrounded the solitary rock. Come back in late June, and the lake will become a pond full of waterplants. And by late July you will be able to walk on the lake bed.
13. We hike back to the walking trail next to the bike trail, and hike back to the Ahwahnee. The entire hike was 7.5 miles, taking 3.5 hours.
14. I have been told that in past years, the park service dredged the Lake of silt. However there has now been a change of policy, deciding to let nature take it's course, and let the silt accumulate year after year. Eventually the water level will decrease with each successive year, with the Lake become shallower and shallower. So you should definitely see the lake while it is still a mirror lake .
