Wilson Trail
Harvard College established the first Mount Wilson Observatory in 1889. The installation of the Harvard telescope in 1889, which brought its own problems of transporting the instrument up the old Wilson trail, caused an interest in a Mt. Wilson roadway, something more than a trail. The Harvard telescope was removed and in July the new toll road was officially opened to the public. The toll was set by the Los Angeles County Board of Supervisors at 25 cents for hikers and 50 cents for horseback. The new road was called the "New Mt. Wilson Trail" and it was more popular at the time than the old Sierra Madre trail. Foot and pack animal traffic became so heavy that in June 1893 the trail was widened to six feet. The Pacific Electric "Red Cars" established their route to Sierra Madre from 1906 until 1950. Thousands of people rode the cars to Sierra Madre to hike the original Mt. Wilson Trail.
