My husband and I are planning a trip out West this upcoming September for 10 days. We are planning on spending the first 3 days in the Grand Tetons. I am debating whether to go along the western part of Colorado and ending our trip in Mesa Verde or going into Utah and ending our trip in Zion National Park. Does anyone have any recommendations on which route would be best? I would love to hike in the San Juan National Park on Colorado, but Zion also looks beautiful.. Thanks for the help!
