Great Sand Dunes National Park, Colorado

Great Sand Dunes National Park is situated near the city of Alamosa in the San Luis Valley of Colorado. It was established as a national park in 2004 on September 13 by Congress and covers almost 70 square miles. Over 250,000 vistors visit the park annually. The park is home to the largest sand dune on the continent. The Dunes are created by wind blowing sediment from the Rio Grande flood plain. Wide ranges of temperature exist in the dunes between the night and day. They are considered a High Desert region but have much milder temperatures than typical High Desert areas. Daytime temperatures will average above 94 F during the day in the summer months and lows dropping to under 0 F during the night in the winter months. Lakes, Mountains, and Forests also exist in the park.

It's a long way from the parking area across to those hills of sand! Quite a workout, but worth every step!
