We rearranged out trip as advice from the forum was not to do Yosemite over the holiday so.... we are now coming from SF the night before and staying in Jamestown overnight ready for a very early start on the Tuesday (29th May) morning. We are not seasoned walkers/hikers but really appreciate the beauty of nature. Can someone tell me the best way to plan the day in the Valley. I know we'll be entering from the Big Oak Flat gate but not sure where we should stop off on the way. Would like to see the waterfalls etc. Would it be best to do a tour? On the way out we will be staying for a night in Mariposa before heading over to Monterey. Would love to see the big trees (think there are some in the Wawano area) but would this be too much driving to come out of the valley and back to Mariposa for around, say 7/8pm?
