Exploring Caddo Lake National Wildlife Refuge: A Comprehensive Visitor Guide
History and Significance
From Cotton Plantations to Wildlife Haven
The land now encompassing the refuge has a rich history. In the 19th century, its fertile soil supported thriving cotton plantations. During World War II, it was transformed into the Longhorn Army Ammunition Plant, producing TNT and other explosives. After the plant’s closure, the U.S. Fish and Wildlife Service took over, establishing the refuge to restore the area to its natural state. Today, remnants of the ammunition plant, such as concrete bunkers and old roads, blend with the regrowing forest, creating a unique blend of history and nature.
Ecological Importance
The refuge’s wetlands and hardwood forests are vital for migratory birds along the Central Flyway. Species like the peregrine falcon, alligator snapping turtle, and Rafinesque’s big-eared bat, some of which are rare or threatened, find sanctuary here. The refuge also plays a key role in combating invasive species like giant salvinia through initiatives like the salvinia weevil program.

The refuge has garnered praise for its solitude, historical intrigue, and natural beauty, though some visitors note challenges like bugs and trail conditions. Here are some highlights from reviews:
Tripadvisor Review: “A great place to see if you like solitude. We loved it. Lots of history. We drove the auto tour. Starr Ranch Road is a must, as well as the old ammunition plant.”
AllTrails Review (Jacob Ledford, September 2022): “The wildlife loop is in good condition and it is a wide trail. There are some bird blinds off the trail, but the path to them is very overgrown.”
Tripadvisor Review: “The wildlife refuge is huge. We enjoyed both the driving tour and several hiking trails. We visited over two days and never saw another person.”
AllTrails Review: “Don’t walk this in the heat of the day, it was miserable. It’s a great trail otherwise. Bring bug spray, the mosquitos and blood flies are out.”
Some visitors have reported issues with ticks and chiggers, particularly on grassy trails, so long pants and insect repellent are recommended. The auto tour is a popular alternative for those who prefer not to hike, though signage can be hard to read from a vehicle, especially in poor weather.
