Things got slightly better when we started hiking up to the Upper Yosemite Falls (6.8mi/10.9km-long hike climbing up 2410ft/735m). These falls were the reason that we decided to go to Yosemite Valley despite knowing that it would mean meeting thousands of other people. Yosemite NP is full of waterfalls and majority of them are at their peak in the month of May. I thought it would be cool to see them since we are in this part of Sierras anyway. In particular, I was interested in Yosemite Falls, which is the highest free-leaping waterfall in North America. From the top of the upper falls to the base of the lower falls it drops the total of 2420ft/739m. The Upper Falls alone drop 1430ft/436m.
The trail to the Upper Yosemite Falls starts with four dozen steep switchbacks, which discourage majority of weekend hikers. After climbing 1000ft/305m the trail reaches Columbia Rock viewpoint that offers spectacular views of Yosemite Valley and Half Dome. Around two thirds of the hikers who made it that far, turn around and do not attempt to go farther up on another set of switchbacks. We made it all the way up, but it was not easy. After the lunch break that we had at the feet of the Upper Yosemite Falls, N. started feeling sick and was moving up at the snail speed. I almost started to have doubts that we would make it to the top of the falls, but luckily we did. He started feeling better as soon as we started going down, which would make me think that he might have an altitude sickness if we were not hiking ~4000ft/1300m higher the previous day without any problems.
Anyway, I am glad that we went for this hike. Seeing the Upper Falls from up-close was amazing, especially that we could observe the rainbow forming there for more than an hour. Also the views of Half Dome and the Valley were pretty spectacular, compensating for the lack of intimacy on the trail.
