Hi! We are planning on a trip in Colorado for 5 days/4nights the second week in September. We will be flying into Denver. What we would really like to do is go to the Great Sand Dunes with possibly going to Colorado Springs (Pikes Peak & Garden of the Gods) and the Rocky Mountain National Park. Any suggestions on the best route for this? Also, is it possible to fit this into our time frame and still enjoy ourselves? We are able to add 1 more day if needed. We would also like some suggestions if there are more beautiful places to visit if you have any. Thank you!
