Alamosa – Located in the heart of the extensive and beautiful San Luis Valley of southern Colorado, Alamosa is one of the most popular cities in the state as far as tourists are concerned. Here the winding Rio Grande River meanders through a high desert valley lined by striking mountains. The Great Sand Dunes National Park is one of the prime attractions of the town. The country’s highest sand dunes, standing tall at 750 feet, and set against the backdrop of a majestic mountain range, attracts visitors from all over the state. Recreational opportunities include hiking, sledding and dune skiing. For nature lovers, there are many trials along with an abundant wildlife to explore in the park. The 18-hole Cattails Golf Course and Luther Bean Museum also merit a visit.
