“Unique, uncrowded place that's worth the drive. Be careful of the altitude!”
We visited the Great Sand Dunes August 13th as part of a Colorado driving vacation. I would highly recommend you visit, even though the park is somewhat off the beaten path (more on that later).
As you approach the park, it is a strange site to see sand dunes rising to a height of 500+ feet. The visitors area is simple and informative, but the real experience is to get out on the dunes and go climbing. There is something very compelling about the chance to climb as high as your energy level permits. I went further then I expected, and found the experience most gratifying.
Several things to remember: The dunes distorts your perspective - everything is further away than it seems, so save enough strength to get back. Bring water on the climb, as you'll need it. Make your way up on the ridges of the dunes. This will not be the most direct route, but it is the easiest walking. Prepare for sand to work its way into everything. Your shoes will quickly fill up with sand, and you should be careful to protect cameras, etc.
MOST IMPORTANTLY: Be careful with the altitude. This was the first place on our Colorado trip that we realized that we had to be very careful with one of my sons, as he experienced some altitude sickness.
TOURING SUGGESTION: People might be deterred from going to the Dunes because they think it's out of the way. However, it's easy to combine the Dunes into the rest of a driving tour. Denver was our first stop in Colorado, we stayed there on a Friday night, visited the Royal Gorge on Saturday, then stayed in Pueblo Saturday night. The Dunes were an easy and scenic drive from Pueblo on Sunday. After we left the Dunes in the early afternoon on Sunday, we drove west all the way to Durango, a lovely drive that takes you over the Continental Divide at Wolf Creek Pass.
