Matanchén as a region includes the bay and a small town with its namesake, and as well the larger community of San Blas. It is known for its exceptionally long surf break. Las Islitas, one of the villages and surfing spots on Matanchén Bay, is documented by the Guinness Book of World Records as having the "World's Longest Surfable Wave" at 5,700 feet (1,700 m). Real estate is limited mostly to San Blas, consisting of single family homes along the beach, and acreage and to Chacala.
The oceanfront community of Chacala has become quite popular recently, for both tourism and real estate. On the north end of Chacala is the Chacala Marina, which is a private gated community with homes situated around the point and in behind and overlooking the marina.
