In the Sierra De La Laguna National Park close to popular Cape Region gateway city of La Paz near the southern tip, the Canon San Bernardo is an easy 14 mile mountain bike trek crossing the Sierras with a 2,300 feet vertical. The route runs east-west from Boca de la Sierra to Santo Domingo.
Note: Prior to 1997, the topographic maps developed by the federal government used the NAD27 CONUS datum. Starting in 1998, the government transitioned to the ITRF92 datum (some maps show both datum), which is pretty much identical to the WGS84 datum.
Overall, Canon San Bernardo is the 11th most popular mountain bike trail of all 24 mountain biking rides in Mexico.
