Who can tell me how is to climb in Yosemite?

At first, don’t be surprised if you find yourself yelling down to your partner, “This 5.9 feels like 5.11!” The good news is that Yosemite climbs are within your grasp; they just take extra patience and resolve. Take solace in the fact that all new Yosemite climbers get humbled at some point but they eventually develop the subtle techniques necessary to move up Yosemite granite. The more time you spend on the rock and more technique you build, the more climbing opens up to you. Suddenly the thousand-foot-tall walls shrink a little and don’t seem as daunting. Before too long you’re planning your ascent of The Nose of El Cap. Find information here: http://www.supertopo.com/climbingareas/bigwalls.html
