Lone Tree at Lone Tree Golf and Event Center

Lone Tree Golf and Event Center sits in Antioch, a city in eastern Contra Costa County along the Sacramento–San Joaquin River Delta. The course was designed by Bob E. Baldock, a prolific Northern California architect whose career spanned from the 1950s through the 1980s. Baldock designed or remodeled more than a hundred courses throughout California and the western United States, often working with municipal clients and creating accessible layouts that emphasized playability across skill levels.

The course occupies relatively flat delta terrain characteristic of the region, where the landscape transitions from the East Bay hills toward the inland waterways. Baldock's routing typically made efficient use of available land while incorporating strategic bunkering and water features to define holes and challenge approach shots. The design reflects mid-century California golf architecture, prioritizing straightforward hole corridors and practical maintenance considerations suitable for a public facility.

Lone Tree functions as both a golf course and event center, serving the Antioch community and surrounding East Bay area. The facility caters to a range of golfers, from beginners to regular players seeking convenient access to the game. Its location in the delta region means the course experiences warm, dry summers and mild winters, with seasonal winds that can influence play, particularly in spring and late afternoon rounds.
