Blas Bay Complejo Ecoturístico

Matanchén is the name of both the bay and one of the small towns located just south of San Blas, Nayarit, on the Pacific coast of Mexico. 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). A local surfer familiar with the conditions was quoted as saying "one quarter to half mile waves are not uncommon."

Matanchén is known for its stunning beaches, warm climate, and friendly locals. The area is a popular destination for those seeking a relaxing holiday, as well as adventure-seekers looking to explore the natural beauty of the region. The beaches are pristine and offer an array of activities such as surfing, swimming, and snorkeling.

One of the main attractions of Matanchén is the wildlife that can be found in the area. The local estuary is home to a variety of bird species, including pelicans, herons, and egrets. Visitors can take a boat tour of the estuary and experience the tranquility of the area while observing the wildlife.
