Great Sand Dunes National Park

We're planning a trip in May with our best friends. They're flying here to Phoenix and we'll drive to Gallup, New Mexico, then head north into Colorado. We'll go first to Durango and meet another couple there whom we haven't seen for many years. Together we'll ride the Silverton Railroad which is a 9-hour round trip. We'll stay another night in Durango before heading east to Alamosa. On the way, we hope to sample the hot springs at Pagosa Springs. Maybe even a bit of white-water rafting if that's available. We'll stay in Alamosa so that we can visit the Great Sand Dunes National Park, something I've wanted to do for a long time. Visit their web site for some spectacular photographs of the dunes. I might have to even get up early to get some good shots. After we explore the park, we'll return west to Mesa Verde and enjoy the magnificent views and architecture of the pueblos. Then back home to Phoenix. It should be a very enjoyable and informative trip.
