On the way to Santa Fe, made a pit stop at the colorado sand dunes!

"Because the dunes and surrounding mountains are designated wilderness, this is a great place to enjoy unspoiled natural beauty in a variety of ways. Whether you play in Medano Creek, build a sand castle, slide down the dunes, go birdwatching in wetlands, or ascend a 13,000' peak, you will discover plenty of kinds of outdoor recreation for all ages."
