💧

Estero Llano Grande State Park

State Park

3301 S. International Blvd, Weslaco, TX 78596

An urban wildlife oasis in the heart of the Valley. The park's shallow lake, resaca wetlands, and brushy edges attract an extraordinary variety of waterbirds and hard-to-find specialties. The visitor center feeders draw Green Jays, Altamira Orioles, and Plain Chachalacas within arm's reach. The lake is one of the most reliable spots in the U.S. for Masked Duck and Northern Jacana.

What the U.S. Fish & Wildlife Service calls the 'jewel of the National Wildlife Refuge System,' Santa Ana protects 2,000 acres of native Tamaulipan thornscrub and riparian forest along the Rio Grande. Seasonal tram tours (typically December through early February) wind through the dense habitat where most of the Valley's RGV specialties can be found in a single morning. The feeder station near the visitor center is exceptional.
