We love La Costa! Centered by a world class resort and spa and golf course, now known as the Omni La Costa Resort and Spa. La Costa is home to many wonderful second and full time residences. Plenty of smaller condo's to larger estate's with clear golf course and ocean views. La Costa is known for its clean living and outdoor amenities and healthy lifestyles. La Costa is in the southern eastern part of Carlsbad and is part of the zip code 92009.
