Imperial Beach is the most Southwesterly city in the continental United States! It is nestled between miles of uncrowded beaches, big surf, and unparalleled open space and wetlands teeming with wildlife. Because this town is one of the last untouched beach communities in Southern California, IB is known as Classic Southern California. The annual Imperial Beach Sandcastle Competition is the largest sandcastle building competition in the US. This festival encompasses a full weekend including a street festival, live music and entertainment. There is much to see and do in Imperial Beach from swimming or surfing at the beach, touring public art, nature walking and bird watching at the world-renowned Tijuana Estuary, or just sitting back, relaxing, and enjoying the sunset from your private patio in one of the least expensive beach front communities in California.
