I never really answered the question from Good to Go regarding the route of the ECR from San Diego to Oceanside.
I've been looking at a lot of sources, which I'll list below, and even the 1903 topographic map shows the Rose Canyon trail as an extant road. So we know it did exist during the early 20th century as a traveled route. Also, several of the auto maps show it, and guide books describe it as a more direct route to Oceanside. I wish I had the sources and maps spoken of by Mrs. Forbes that were used to trace the ECR route, but I don't. Instead, I'm using as my standard, two sets of 3 strip maps from the Automobile Club of Southern California. The first is a set of three maps from the January, February, and March 1912 issues of Touring Topics (the ACSC magazine). These are dated: San Diego to Los Angeles — 20 Dec 1911, Los Angeles to San Luis Obispo — 24 Jan 1912, and San Luis Obispo to San Francisco — 24 Feb 1912. The title does say "El Camino Real and
Popular Automobile Routes to and from Famous Missions." To me this implies the routes shown are not always the ECR but are those preferred by drivers and the Club. The other set of 3 is the one that Good to Go discussed, and that is maps 212, 213, and 214, "Famous Missions in California on El Camino Real ." These two sets are not as detailed as other ACSC strip maps, so I give additional status to strip maps from the period before 1918.
I guess I should say my goal is not to find and follow the El Camino Real of the padres, but instead to trace the automobile route to the missions along which many bells were placed. Mrs. Forbes stated that of the 75 miles of ECR in San Diego County, every mile had a bell (ie. 75 bells). I wish that were still true. Many of the bells that do exist are later, from the time of post-1926 US 101 and others are from much later and were placed in odd locations such as the two downtown Escondido.
Still, even the maps I'm using as standards do not obviously follow Mrs Forbe's ECR in a few obvious cases. One is the route from the San Diego Mission to old town. This was obviously the road which ran on the south side of Mission Valley (Taylor Street and Camino del Rio, aka Mission Valley Road, the I-8 path today). This road is
not shown on either of the ECR strip map sets. Instead the route used to reach the mission is the early path of the Inland Route to Poway and Escondido. It followed the following route to the Mission: 5th Street to University, University to Normal, Normal to Park, Park to Mission (a telling name), Mission to Madison, and Madison to Ward Road (Madison is now cut by I-805). Ward now runs into Ward Canyon Park, but it once ran down Ward Canyon instead of I-15. A small remnant of Ward Road also exists at the bottom of the hill, meeting up with Camino del Rio North. Ward here now becomes Rancho Mission Road, then a right turn on San Diego Mission Road takes you to the mission.
