San Blas Bay hosts several islands of different size, separated from the mainland by estuaries or entrances of the sea. The most important one is Isla Jabalí, where there is the sea village that has the same name as the bay.

San Blas is linked to the history of Carmen de Patagones and it knew eras of corsairs and adventurers who toured the north-Patagonian shore. It was also the land of landlords who fought for it with the Indians. One of the latest battles took place in 1870. An English cattle-farming company, Mulhall, Buckland and Peirano exploited the Gama and Jabalí Islands and it sent salt shipments from there. Nowadays, Jabalí island is the center of tourist activities linked to fishing while Gama Island, the wildest one, is populated by rheas and wild boars.

San Blas Bay, also known as “Fishermen’s Paradise” or “Shark’s Mecca” is a true fishing village. Everything there has been thought around fishing: specialized shops with a broad variety of hooks and fishing lines, fishing tackle rental and sale, bait sale, fishing tours with a guide, ships for rental, and even restaurants and barbeque places where they cook what you have caught.

The special feature of this colorful pebble coast is a significant slope, also near the coast, the depth is of 15 meters, a fact that allows for good castings from the shore. The calm waters, with little waves turn it into a true sea well.

Playa de Arena is a bit further ahead, this area is ideal for fishing small sharks, specially from September to December. The ones who accompany the fishermen can bathe in the sea, the sharks are not to be feared since they are not aggressive species. During low-tide you can find clams on the beach that are used as bait.

San Blas has a wide offer of motorboats that tempt fishermen to get into the sea to try better casts. The drivers are experts who know the channels, the currents and the banks. Besides, most of them have devices that allow for the detection of shoals of fish, a guarantee for fishing success.
Among the permanent services in the village, there is a first aid room, a police station, phone booths, gas station and mechanical shops.
