I climbed GP on perhaps the hottest day of the year. Nevertheless, it was actually a pleasant hike, as things cooled down the higher we got. We just made sure to take a lot of gatorade, water, and bananas. I especially enjoyed the amazing contrasts: pine trees and views of the searing sonoran desert landscape below.
Nice climb in perfect weather. The kids enjoyed it too!
camped at the base, nice hike carried three year old daughter up. Temp around freezing at the top 30-40 mph wind. Clear great views. An interesting and worthwhile climb.
Very windy night in the tent at the campground near the trailhead. It was still quite windy at dawn when I left but the wind lessened quickly and was just a nice breeze when I arrived at the top mid-morning. Great views, especially the back side of El Capitan. Neat walk on easy trail. A little ice in shaded areas near the top (It was very close to Christmas). I didn't see another person until I started down. I recommend the drive south from the park. Very few people, big views and some stunning cliffs to the west.
