But to get to the Dunes from Humboldt (by car)
you have to drive all the way around the Sangre de Cristo range to access the park. We opted to drive the 2.5 hours south towards New Mexico to wrap around the mountains to reach the other side.
We reached the park entrance, packed up some camping stuff and ventured out onto the dunes in the dark. It was pretty trippy walking up and over the dunes illuminated by the stars and our headlamps. It was really hard to tell how big or steep the dunes were in the dark, but we tracked the ridge line via GPS.
After about a mile of walking we put up the tent in a flat spot, had a beer, and took some photos. In the morning we ventured up High Dune (they all look the same) and the dunes weren’t quite as steep as they seemed the night before in the dark. The high winds blew plenty of sand into the tent (I had my camera sealed in a garbage bag) so we shook sand out of everything before making our way back to the parking lot.
