San Francisco, California
Very long day (15 hours) but well worth the trip!! Highly recommended......caution, the first stop in Yosemite is to view the giant sequoias. This is a journey that requires a hike down a paved path and back up a very steep hill. For a person that is in good shape, you're looking at an hour round-trip. For those that have trouble with walking and standing, my advice is to stay on the bus for this portion of the tour. Once you leave here, you go straight to the valley and there is no physical exertion required.
Las Vegas, Nevada
I give this trip a 4-star rating due to the sheer beauty of the canyon. The bus driver (Gene) was incredible with superior knowledge of the whole area to include the Canyon and Vegas. Unfortunately, the bus company was obviously not prepared to handle the high demand of visitors to the West rim of the Canyon so it turned out to be a 14.5 hour day! The extremely long day put somewhat of a damper on the tour but it still was well worth it. The Skywalk is a little overrated but the views are breath taking.
