Our family of 4 (sons 17 and 19) were able to see the best of Yosemite all in one day, thanks to Pat. He picked us up at 7am at our hotel and we were able to start a hike in total silence before the rest of the tourists started! He knows how to time the attractions so that you do not feel like you are amongst a bunch of tourists. He also knows alternate trails to use to avoid any crowds. Pat is kind and wants to know what YOU want to do. He will cater the day the best that he can so that you are happy. He has a wonderful sense of humor and is so easy to talk to. You can tell that he really enjoys what he does. We would highly recommend Pat. You won't be sorry!
