The Rio Grande Valley has a variety of habitats that support a large number of species of birds and butterflies which in turn provide great opportunities for view wildlife. The following destinations are listed in order of proximity to Trails End Park. Each is somewhat unique and provide a different nature appreciation experience. All of these locations have really great staff and programs so check them out yourself or ask me about these or other prime locations.
1) Frontera Audubon is a 15 acre sanctuary two blocks north of Trails End just off 18th Street. There are quiet trails that meander through the ponds and lush vegetation on this property.
3) Estero Llano Grande State Park off 1015 Hwy on the East side of Weslaco is a premier wetland birding location in the RGV. Their staff have regularly scheduled bird and butterfly walks and tram rides by appointment.
