After Mesa Verde, are next stop was the Great Sand Dunes in CO. Next to the Grand Canyons, this was my favorite spot. I wasn't expecting much, but was more than pleasantly surprised. These dunes were fascinating. We were there after the creeks were drying up, but would love to go back.
Also, there were lots of hiking trails on the mountains near the Great Sand Dunes. One takes you to an amazing waterfall.
And like the Grand Canyon, pictures just does not do it justice!!!
