Deerfield Lakes Golf Course is a public facility located in Callahan, a small town in Nassau County in northeast Florida, roughly twenty miles north of Jacksonville. The course serves the surrounding communities in this part of the First Coast region, where residential development has gradually expanded into formerly rural areas. The layout occupies gently rolling terrain typical of the coastal plain, with natural wetlands and lakes integrated into the design as both hazards and environmental features. The course reflects the practical design approach common to many Florida daily-fee facilities built to accommodate a range of skill levels while managing maintenance costs in the region's humid subtropical climate. Water comes into play on multiple holes, and the routing takes advantage of existing topography and native vegetation to create variety without extensive earthmoving. Bermudagrass is the standard playing surface for both fairways and greens in this climate zone. Callahan's location along U.S. Route 1 and Interstate 95 makes Deerfield Lakes accessible to both local residents and travelers passing through northeast Florida. The course operates as a straightforward public golf amenity in a region where the game remains popular year-round, though summer heat and afternoon thunderstorms are seasonal considerations. The facility provides a golf option in Nassau County, which has fewer courses than neighboring Duval County to the south.
