to the Great Sand Dunes Oasis
The Gateway to Recreation in the
Great Sand Dunes National Park and Preserve!
On the eastern side of the remote, high-mountain San Luis
Valley, between the Blanca Massif and Crestone Needle, are
the Great Sand Dunes, the tallest sand dunes in North America.
The dunes cover approximately 39 square miles and rise to
almost 750' above the valley floor.
dunes are the product of the wind and rain eroding the San
Juan and Sangre de Cristo Mountains that ring the San Luis
Valley. They have collected here because the prevailing
winds across the valley blow in this direction. But here,
at the foot of the mountians, the wind has to drop some
of its load of sand in order to clear the mountains. So
over the course of millenia, the dunes have built up to
where they are today. And tomorrow they will be different
because the wind still blows and still moves and deposits
more sand here.
