Canyons Transport is the way to go to get you up to the Alta -Snowbird area from the Salt Lake City Airport or nearby downtown hotels. The ride is about 45 minutes and you do not need a car while you’re up in Alta/Snowbird to get around.
I have taken many shuttle company rides on many past travel destinations but have to say Canyon Transport was the best one overall I have ever booked with. They had impeccable service, promptness, reliability, friendliness and safe drivers. Overall, I would rate them a 10 out of 10. They were flexible on updates and changes.
