Yosemite Falls upper and lower.

Yosemite National Park is a fairly interesting four hour drive from San Francisco and then its about two more really interesting hours to get into the valley. Its easy to drive to the park edge after work, stay at a hotel right outside the border then go into the valley the next day. I've never met anyone who didn't absolutely love the place and wanted to take a million pictures of everything, one of those places you have to see at least once in your lifetime. Its best in the spring, thats when the waterfalls are in full force, drive to the valley early then hike to one of them. There are several different hiking options from easy to extreme so you can pick one you know you can handle. Check out the Yosemite Blog for more information.
