I am flying into San Diego and passing through Nevada for 1 day not staying the night. Mainly want to focus on Utah the 21st to the 25th (Fly out afternoon of the 26th). I am going to be going solo. I am active and outdoorsy but I am finding that Utah in August is a rough time to do outdoorsy activities in the afternoon hours. Can someone suggest an itinerary from Vegas to Salt Lake City from the 21st to 26th. I have never been to Utah and would really like to hike, kayak, etc... Can I book hotels/Airbnbs in areas with national parks withing 30 minutes within a week? Also what are recommendations of top cities to visit along the path? Suggestions welcomed.
