Camp Fremont was a major United States Army training base that occupied a large swath of the Menlo Park area during World War I. Established in 1917, it trained infantry divisions destined for the Western Front and became a significant presence in what was then largely agricultural land on the San Francisco Peninsula. The camp's footprint extended through what are now the residential streets of Menlo Park and Palo Alto.
Little physical evidence of the camp survives today — the streets of the residential neighbourhoods have absorbed the former parade grounds and barracks areas — but a historic marker near Willow Road marks the site. The Menlo Park Caltrain station area was the main entry point for troops arriving from San Francisco. For visitors interested in local history, the Menlo Park Library and the Palo Alto Historical Association maintain archives relating to the camp's years of operation, including photographs of the tented barracks that once covered the flat ground between the bay and the foothills.
