Cardiff-by-the-Sea, often referred to as simply Cardiff, is a beach community located between Encinitas and Solana Beach. Encinitas on its north eastern border, and the beach and lagoon are to the south. With a population just under 12,000, Cardiff-by-the-Sea operates as part of the city of Encinitas.
Over eighty years ago, this farming community in the hills north of the San Elijo Lagoon began to take root and grow. Many streets in
Cardiff bear UK names such as Birmingham, Oxford, Chesterfield, and Manchester because of its original development by an Englishman.
