The Filoli trail system is comprised of a network of twenty-two trails totaling more than five miles. The trails are both historic Filoli dirt roads and trails that have been constructed by Filoli volunteers to provide access to the nature preserve. The trails are accessible only during Filoli docent-led hikes and activities. The typical hike takes about two hours and a has a maximum elevation gain of about 250 feet.

The oldest road on the property is the old Cañada Road, which was a major transportation route along the Peninsula before the Bourns acquired the Filoli property. The Bourns had the road relocated to its present right of way along the San Francisco Watershed land to the east of Filoli. Other roads were constructed by the Bourns to provide access to the reservoir, dormitories and other sites.
In the late 1980s, it was proposed that the trail system be expanded and off-road paths be built for greater access to the land for educational and interpretive purposes. As a result the Trails and Grounds Committee was formed.
