This photo is framed for a historical record. It is not a pretty picture per se , but accurate as to the Royal Road from Mexico City northward to Santa Fe, the pueblos, and Taos.
According to Spanish documents, this final part of the Royal Road leading to Taos went from Trampas to Picuris Pueblo, slightly east to Vadito, then up Telephone Canyon around Picuris Peak, and then connecting with the Arroyo Miranda, traversing the east side of the arroyo. The above photograph is looking south, up towards the Picuris Peak area. Lying behind me is Talpa that is close to Rancho de Taos and Taos.
The map below indicates the route into Rancho de Taos. Note Telephone Canyon, Arroyo Miranda, Rancho de Taos, and Taos.
The following are my field notes from the trip, showing the route as I described.
The El Camino Real is only partially open to public transit through the Carson National Forest. The final leg is on private land and closed to public transit. The Royal Road, however, can be followed within two miles of Talpa and one can sidestep to SH 518 and hike into Taos.
