Yosemite is a wonderful place to put on your bucket list.
Almost noone will climb the face of El Capitan but there are some spectacular and highly demanding walks for the experienced. As well as some easy walks for the quite fit.
For a serious and very fit walker with a steady head for appaling feelings of vulnerability, do the climb to the summit of Half Dome ( easy to spot in pictures as it looks as it is called ). The last section makes you feel vulnerable and is cable assisted over slick rock.
For fit but more cautious walkers there are great walks based on the falls.
An easy path, albeit initially steep, leading to a spectacular overlook of the whole valley and over to Half Dome, is the Inspiration Point walk. There's actually a cafe at the top and lo and behold, when you get there you see that you could have just driven up the other side ! Fabulous view here for the unfit.
The immediate park itself is worth at least two days on a tour. But also, the surrounding area is full of great scenery and things to do. Almost all organised tours make the mistake of just breezing through Yosemite. Even most peoples self guided tours do the same albeit less so, but usually don't do it justice. I always advocate on trips such as these, to cover a lesser area and do where you visit really well, rather than cast yourself over too large an area, have too much driving and leaving areas feeling short changed. So like on a two week ( or even a three week ) road trip in the area, don't be silly like many people and try to do a huge California/Navada loop. Focus, say on a smaller California loop out of San Francisco, covering parts of the coast and come inland through the "Gold Country" to the Sierra Nevada mountains and maybe Lake Tahoe. Doesn't have to be that but I hope you get my point. Go smaller and longer in each place rather than skim over place on mad routes.
