Laguna Niguel is an affluent, master planned community located in the coastal San Joaquin Hills of southern Orange County, California. Laguna Niguel occupies a hilly basin near the southern end of the San Joaquin Hills, a small coastal mountain range in southern Orange County.
Crown Valley and Alicia Parkways are the primary thoroughfares in the city. Crown Valley Parkway runs along Sulphur Creek and the northern fork of Salt Creek, bisecting the city northeast to southwest. Alicia Parkway, mostly a north-south road, follows Aliso Creek to where it joins Crown Valley Parkway in close proximity to Crown Valley Park and the city center. California State Route 73 runs north of the city, diverging from Interstate 5 just northeast of Laguna Niguel. Moulton Parkway/Street of the Golden Lantern runs along the eastern boundary of Laguna Niguel. Pacific Island Drive/Camino del Avión follow parts of the west and south boundaries, respectively. Another major road, Niguel Road, runs roughly parallel and east of Crown Valley Parkway along the Salt Creek canyon. Marina Hills Drive is the largest crossing between Niguel Road and Golden Lantern, and Aliso Creek Road runs east-west through northern Laguna Niguel.
