Mills Canyon Nature Area Trails Professional Guide
Detailed Trail Description from our Guidebook
"Under Mexican rule, Mills Canyon was part of Rancho Buri Buri, which included most of northeast San Mateo County, extending as far south as present-day San Mateo. In the early 1860s Darius Ogden Mills and his brother-in-law, Ansel Easton, each bought 1500 acres of Rancho Buri Buri. The division between their two holdings ran straight through this canyon. Most of Mills’ estate was in contemporary Millbrae, but this land, including the upper part of this canyon which takes his name, was eventually annexed to Burlingame."
