I want to enjoy long tour with friend,

I want to enjoy long tour with friend. I asked my friends about this. They are ready to go with me. We booked an 11-day Las Vegas to Salt Lake City, St. George, Jackson, Rocky Mountain, Crazy Horse Monument, Casper, San Diego, Santa Barbara, and Grand Teton National Park Tour (Free Airport Pickup) by GoldenBusTours. We want to enjoy hiking on this tour. So suggest to me the best spot there which will remain best to enjoy this activity. I will wait for your reply...
