To facilitate overland travel, the mission settlements were situated approximately 30 miles (48 kilometers) apart, about one
day's journey on horseback, or three days on foot. The entire trail eventually became a 600-mile (966-kilometer) long "California Mission Trail."
Rev. Lasuén successfully argued that filling in the empty spaces along
El Camino Real with additional outposts would provide much-needed rest stops where travelers could take lodging in relative safety and comfort. Heavy freight movement was practical only via water. Tradition has it that the padres sprinkled
mustard seeds along the trail to mark it with
bright yellow flowers. Today a growing number of people, calling themselves
California Mission Walkers, hike the mission trail route, usually in segments between the missions. Walking the trail is a way to connect with the history of the missions. For some it represents a spiritual pilgrimage, inspired by Jesuit priest Richard Roos' 1985 book, Christwalk. The loosely organized group is attempting to formalize the route and establish markers, similar to the
El Camino de Santiago, in Spain. ==Missions==
