Leaving from several downtown San Francisco hotels the Incredible Adventures gives visitors a stop in California's Central Valley for breakfast and enter Yosemite from the south. Orientation to the valley includes views, shopping and lunch. In the afternoon, you will have three hours to do whatever you want, and after further guided touring through the valley, you will return to San Francisco sometime evening. This one-day adventure is charged per person. The three-day adventure starts much the same way, but you will be camping for two nights in the valley. The emphasis on these trips is guided and unguided hikes.
