We started at the Gardner Meadow Trailhead (8575 ft), off Hwy 4 west of the Ebbetts Pass summit (the steep, dirt access road was somewhat taxing for Greg and his little Golf...).
We followed the Pacific Crest Trail for a while, turned off towards Adams Camp, and headed back across Upper Gardner Meadow.
The first day we were very very slow, averaging only about 1 Mile/hour, which surprised us, until we realized we're walking around at ~ 9000 ft (high point of the trail was 9340 ft, i.e. ~ 2800m).
On the second day we got lost a little and had to rely on Greg and his compass to get us back to the trail.
The third day was easy walking through a very pretty meadow.

A great birthday-trip!
