On January 1, I was worried that the road would be blocked due to snow, and I thought that it would be impossible for us to do such a difficult thing on a day trip, so we participated. Although my stay was short, about 4 hours, I was able to visit places with beautiful scenery by stopping here and there, listening to explanations, and being able to take pictures. On the round-trip bus, they explain San Francisco and Yosemite, and show you a video of Yosemite, so you won't get bored. Also, for us, it was a good break during the trip because we were able to go while sleeping. It was a very satisfying tour blessed with good weather.
