The Tour was nice and the Guide was very knowlegdable, he even told us many things about the landscape and agriculture along the way to Yosemite. In the park itself, we had about 3 hours on our own, which we thought was not enough given the many things you are able to see in this wonderful piece of planet earth. However, we made it up to Columbia Rock had a stunning view. Its a steep hike and you dont have much time for little breaks otherwise you wont make it back in time. On the way back, the Guide even dropped us at our preferred location instead of the pickup point. Overall I would recommend this tour very much!
