Laguna Atascosa Challenge Professional Review and Guide
"A ride north from the historic lighthouse in Port Isabel passes through cultivated fields and grazing pastures on the way to a magnificent wildlife refuge preserved at Laguna Atascosa. This route can be divided into two shorter options. One visits only the flat farmland now characteristic of most of the countryside in the Rio Grande Valley. The other visits only the carefully preserved habitat within the national wildlife refuge. Combining the two on the full tour illustrates the different ways our environment can be influenced. Grassland, wetland, and brushland once covered this part of south Texas inland from the shores of Laguna Madre and Padre Island.
Over time, grasslands were overgrazed by cattle, wetlands were bulldozed into fields for sugarcane and cotton, and brushlands were cleared for development. However, native vegetation remains here in Laguna Atascosa National Wildlife Refuge. Terrain: flat. Road: Texas 100 is busy but with a wide shoulder, although some cars use the shoulder for parking in town. FM roads are two lanes, light traffic. County roads are narrow, light traffic. Portions of Bayside Dr. are unpaved and better suited to an all-terrain bike."
