A Hidden Gem in the Great Plains
This is a hidden gem of a canyon in the Great Plains. I live nearby in Raton and even in the county seat our population has declined since the coal mines closed not too long ago. Nearby Roy, the closest town to Mill's Canyon, is nearly a ghost town now.
So we could use the tourism. We're not overrun like Santa Fe or Taos, both only a couple of hours or so away from Mill's Canyon.
The canyon hides from view until the last moment and then the red rock walls and meandering river come into view at the rim. The upper canyon campground is best for those with larger trailers, as the road down, while smooth enough, has tight turns. I'd at least unhitch, park and then drive down without a trailer first.
I've driven a Prius up and down the road, so it's not that challenging, although there are additional dirt routes on the valley floor that offer dispersed camping opportunities for those seeking yet more solitude better suited for higher clearance vehicles. I've never seen the official campground, complete with picnic tables, fire grills, and vault toilets crowded though. It's right by the stream, which is sometimes mere puddles, and sometimes knee deep.
There are stone hotel and ranch ruins from the stage coach days nearby, and clams shells in the riverbed. It's beautiful.
Charette Lakes, Capulin Volcano, Cimerron Canyon and Sugarite State Park are all within an hour or so drive, making Mill's Canyon but one choice for camping & exploring in the area.
