Yosemite was amazing, only complaint was that it felt like a very rushed trip.
The tour was very well organized and as described on Viator. But if you would really like to see everything what Yosemite park can offer, you should check other options 3h that we had available for sightseeing were not enough.
Great trip, wonderful, knowlegeable tour guides! Very long day! More guided tour time would be the only thing I would change.
