About
Salt air and the rustle of the mangroves are the atmosphere at Estuary El Soldado, where land and sea come together in a real patch of biological diversity. It's one of Sonora's most important wetland reserves, covering about 180 hectares of mangroves, mudflats, and tidal channels.
It's gone from being a fairly unremarkable bit of coastline to one of the most important wetland refuges in the state, a place of great value for wildlife, for environmental education and for eco-tourism.
There's been a lot of work over the years by the local conservation groups and the volunteer network to restore the habitat, to study the migratory patterns, and to just get the community to appreciate what the estuary is and what it does.
El Soldado is more than just a pretty place, really. It's a working classroom, a haven for rare and endangered species. It's a natural filter which protects the coast from erosion and provides a nursery for fish, crabs and all sorts of marine life. The biodiversity of the estuary is absolutely staggering, from the tiniest fiddler crabs right up to the beautiful roseate spoonbill.There are guided walks, kayak trips and all sorts of educational programs available via the visitor center and a number oflocal environmental groups, so there's a good opportunity for everyone to get involved and learn about this special environment.
Whether you're a keen birder, a photography enthusiast or simply looking for a peaceful place to get away from it all, Estuary El Soldado is a great place to visit. The trails and boardwalks are perfect for slow exploration and just taking it all in. There are plenty of interpretive signs and guides on hand to tell you the stories of this important ecosystem.
Estuary El Soldado: Fun Facts & Cool Features
This natural wonder is a birdwatcher's dream. Over 200 species have been recorded there (herons, egrets, ospreys, various migratory songbirds, etc.). In the winter, you get flocks of white pelicans and some very rare black-necked stilts. The mangroves are interesting in their own right, with aerial roots projecting well above the mud and providing cover for a whole host of animals, from juvenile fish to the rather inquisitive raccoon.
The estuary has a very distinctive tidal flow which produces all sorts of different patterns in the mudflats and channels.You can kayak through the quiet water and see blue crabs, mudskippers, and, on occasion, a bottlenose dolphin right at the mouth of the estuary.
The visitor center has a number of exhibits on the local flora and fauna and also on the various sustainability initiatives in place to protect this very fragile environment. There are regular guided walks and nature talks, all delivered by local experts who are genuinely passionate about the area and about conservation.
The estuary also acts as an outdoor classroom for local schools with regular workshops and field trips run there to engage the next generation of environmentalists. There are all sorts of community events too, from clean-up days to art installations and citizen science projects.
Estuary El Soldado offers wildlife, peaceful scenery, and the chance to get hands-on with the environment. It's essential for anyone who wants to experience the wild heart of San Carlos.
