Laguna Madre is a coastal lagoon located along the southern Texas coast and northern Mexico. It is known for its shallow waters and unique ecosystem, which supports a variety of wildlife, including birds and fish. The lagoon is separated from the Gulf of Mexico by a barrier island, South Padre Island, making it a popular spot for recreational activities like fishing and birdwatching. The lagoon is also significant for its salt flats and seagrass beds, which provide essential habitats for marine life. Laguna Atascosa National Wildlife Refuge is nearby, protecting the area's biodiversity and offering opportunities for nature enthusiasts to explore the region's natural beauty.
