Chimney Rock Loop Professional Guide
Detailed Trail Description from our Guidebook
"This is a long loop on the roads west of Pagosa Springs. CO 151 is a real gem, with rolling terrain and relatively light traffic.
The centerpiece of this long, gorgeous, and slightly obscure loop is Chimney Rock, not because the phallic rock formation is particularly wonderful to look at, but because of the amazing prehistoric ruins that are located up there, along the sharp Pagosa hot springs."
