🇸🇻 El Salvador · Pacific Coast
Bahía de Jiquilisco is one of the most impressive and least-known natural treasures of El Salvador: the country's largest estuary and wetland, a vast maze of islands, channels, mangroves and beaches on the Pacific coast of the department of Usulután. Declared a Biosphere Reserve by UNESCO and a wetland of international importance (Ramsar site), it's a sanctuary of biodiversity, a refuge for migratory birds and one of the most important sea turtle nesting areas in the region.
Very different from the popular Salvadoran surf beaches, Bahía de Jiquilisco is a destination of ecotourism, nature and tranquility. Here you cruise by boat through tunnels of mangrove, watch birds, visit islands with almost pristine beaches and get to know community turtle conservation projects. It's a place to disconnect, marvel at nature and discover a different face of El Salvador, far from the crowds.
This guide covers Bahía de Jiquilisco with a practical and warm eye: how to navigate the estuary and its mangroves, where to watch birds and turtles, which islands and beaches to visit, how to get there and what to keep in mind for a responsible visit to this fragile ecosystem. It's a must-see destination for nature lovers and for anyone who wants to experience the wildest, most serene side of the Salvadoran Pacific.
Bahía de Jiquilisco, on the coastal east of El Salvador, is an estuary formed by the mouths of rivers on the Pacific, which gave rise to an extensive system of islands, channels, mangroves, tidal creeks and beaches. The area has been inhabited and used since pre-Hispanic times by communities linked to fishing, the gathering of mollusks (like the mangrove cockles, or 'curiles') and the resources of the estuary; the name Jiquilisco itself has a Nahuat root. During the colonial and republican periods, the Usulután region became linked to agriculture and, later, to crops like cotton and sugarcane, while the coastal communities continued to depend on the sea and the mangroves. The great ecological value of the bay —one of the most important wetlands in Central America— gained recognition over time. Bahía de Jiquilisco was declared a Ramsar site (wetland of international importance) for its relevance to aquatic and migratory birds, and later the area was recognized by UNESCO as a Biosphere Reserve (the Xiriualtique-Jiquilisco Biosphere Reserve), which reinforced its protection and its profile as a destination for ecotourism and conservation. Today, the bay is the setting for important community and organization projects dedicated to protecting sea turtles —which nest on its beaches— and the mangroves, as well as sustainable tourism initiatives that seek to reconcile conservation with the development of local communities.

Origins, formation and what the sources say.
Bahía de Jiquilisco is, above all, a work of nature. It's the largest estuary in El Salvador, formed by the mouths of rivers on the Pacific Ocean, on the coast of the department of Usulután. There, where the fresh water of the rivers meets the salt water of the sea, a complex system of brackish water was generated that gave rise to a vast maze of islands, peninsulas, channels, tidal creeks and, above all, mangroves.
The mangroves are the soul of the bay. These forests of trees adapted to live between land and salt water perform fundamental ecological functions: their roots serve as a nursery and refuge for countless species of fish, mollusks and crustaceans; they protect the coast from erosion and storms; and they sustain one of the greatest concentrations of biodiversity in the country. It's one of the most extensive and important mangrove systems in Central America.
This ecosystem, shaped over thousands of years by the interaction between the sea, the rivers and the vegetation, is what makes Bahía de Jiquilisco such a special place. Its geography of islands and channels and its biological richness are the basis of everything that came after: the life of the coastal communities, its ecological value and its international recognition.
Bahía de Jiquilisco has been inhabited and used by human communities since pre-Hispanic times. The Indigenous peoples of the area —of Nahuat roots, as the name Jiquilisco itself reflects— and, later, the colonial and republican coastal communities, found in the estuary and its mangroves an abundant source of food and sustenance.
The life of these communities traditionally revolved around artisanal fishing and the gathering of the mangrove's resources, especially mollusks like the cockles or 'curiles', which are extracted from the mud among the mangrove roots and are a typical product of the area's cuisine. Fishing for fish and shrimp, extracting cockles and using the estuary's resources formed a coastal culture closely tied to the rhythm of the tides and the health of the mangroves.
These communities, spread across the islands and shores of the bay, maintain much of those traditions to this day. Their relationship with the estuary is, at the same time, a source of life and a conservation challenge, since the sustainability of the fishing and gathering depends on keeping healthy the ecosystem they depend on.
The extraordinary ecological value of Bahía de Jiquilisco gained recognition as awareness grew about the importance of wetlands and biodiversity. The bay was declared a Ramsar site, that is, a wetland of international importance under the Ramsar Convention, by virtue of its relevance to aquatic and migratory birds and to the conservation of the mangrove and estuary ecosystems.
Later, the area received an even greater recognition by being incorporated by UNESCO as a Biosphere Reserve, within its 'Man and the Biosphere' program (MAB), under the name Xiriualtique-Jiquilisco Biosphere Reserve. This category recognizes not only the natural value of the area, but also the goal of reconciling the conservation of biodiversity with sustainable development and the well-being of the human communities that inhabit it.
These international recognitions reinforced the protection of the bay and its profile as a destination for ecotourism and conservation. They made Bahía de Jiquilisco an environmental reference point for El Salvador and the region, and a place where nature, science and local communities meet around the challenge of preserving a unique ecosystem.
One of the most important chapters of the recent history of Bahía de Jiquilisco is the effort to conserve sea turtles. The beaches of the bay and its islands are one of the most important turtle nesting areas in El Salvador, including threatened species like the hawksbill turtle, considered endangered, in addition to the olive ridley turtle and others. This made the bay a key setting for the protection of these species.
In the area, community and organization projects dedicated to protecting the turtles operate: they collect and safeguard the eggs in hatcheries to prevent poaching and predation, care for the hatchlings and release them into the sea, contributing to the survival of threatened populations. These projects have involved the local communities, also offering economic alternatives tied to conservation and responsible tourism.
Hand in hand with these efforts, Bahía de Jiquilisco developed as a community ecotourism destination: boat rides through the mangroves, birdwatching, visits to the turtle projects and stays at lodgings that support the communities. This approach seeks to reconcile the conservation of the fragile ecosystem with the development of the local populations, showing that protecting nature can also be a source of future. For the visitor, the bay thus offers an authentic and meaningful nature experience, in one of the most valuable corners of El Salvador.
