Estero Llano Grande State Park
Welcome to Estero Llano Grande State Park
Welcome to Estero Llano Grande

At the geographic center of the World Birding Center network, Estero Llano Grande in Weslaco attracts a spectacular array of South Texas wildlife with its varied landscape of shallow lake, woodlands and thorn forest. Even beginning birders and nature lovers will enjoy exploring this 230 plus-acre refuge, which is convenient to all the Rio Grande Valley has to offer.

The Land
Water is the magic ingredient for attracting wildlife, and Estero Llano Grande State Park offers something special as the largest wetlands environment in the World Birding Center network. A shallow lake, fringed with marsh cane, is actually part of the Arroyo Colorado. Classic Rio Grande woodlands add variety to a park that already boasts a well-deserved birding reputation. As part of extensive restoration plans, a former agricultural field has been transformed into wetlands, with an island just right for a secure nesting site.
Estero Llano Our Birds Our Birds
Estero Llano Grande has a well-deserved reputation as a can’t-miss birding destination. In late summer, when water is at a premium, hundreds of waders & shorebirds flock here, including the endangered Wood Stork, along with colorful coastal species like the Roseate Spoonbill and Ibis. Migrating waterfowl also make a beeline for the park’s narrow, shallow lake. Elsewhere, woodland & thorn scrub harbor all the must-see Valley specialties such as the Groove-billed Ani & Altamira Oriole. Adding spice to this mix, visitors may even spot rare Red-crowned Parrots and Green Parakeets.
