The San Luis Valley is over 80 miles long and 50 miles wide.
Spectacular mountain ranges surround the valley.
On the west side, the San Juans create the perfect backdrop for our colorful sunsets. Looking east, you'll see the spiny Sangre de Cristo range, which is among the tallest mountain ranges in Colorado. Mt. Blanca, in the heart of the Sangre de Cristo's, is the fourth tallest mountain in the state. From just about everywhere in the valley, you'll have stunning views of this beautiful mountain. Alamosa, with a population close to 8,000, is the largest city in the San Luis Valley.
