Alternate routes to access Upper Huerfano basin

The US Forest Service is currently recommending visitors use alternate routes to access the upper Huerfano basin, Lily Lake, and the 14ers.

  • Mosca Pass Road 583 summit, then traversing south near Carbonate Peak to the basin
  • Holbrook Gulch Road # 975 to Lake Como from the Rio Grande NF side
  • South Zapata Creek Trailhead in the Zapata Falls Recreation Area (south of Sand Dunes N.P.)
  • Cascade Creek Trail #1303 from the Huerfano State Wildlife Area ,to the Huerfano Trail # 1307 which ends on FSR 580 above the slide.
All routes listed require back county skills and preparedness. The US Forest Service has not published a map of these routes, instead they ask to reference the National Geographic Sangre de Cristo map for detailed route planning.
