My first time visiting Yosemite Valley (guilty California native) and I did this 14 hour hike up to the Half Dome.
Making it to the guy who asked for our permits, I thought we were there, nope. Another brutal steep hike up to subdome tested my determination for another hour.
Though underwhelmed by the view, the feeling of accomplishment made it all worthwhile.
Definitely recommend the experience. Probably just a one time experience for me though. Just trying to experience what this world has to offer.
