This semi-paved, 15-mile, one-way loop passes through thorn forest and coastal prairies before reaching the Laguna Madre. The shelter at Redhead Ridge Overlook and numerous pullouts allow for nature photography and viewing.

Lakeside Drive

It's only a short 1 ½ miles out to the lake that gives the refuge its name. Atascosa means "muddy" in Spanish, which describes the shallow lake on windy days. The lake is an important resting and feeding area for the more than 20 species of waterfowl that winter here. Osprey Overlook features two permanently mounted telescopes for a closer look.

Kiskadee Trail

(1/8 mile) starts between the Visitor Center and the refuge office building. This short, shaded loop surrounds a shallow pond that holds water in wet years. Featuring an observation deck and small bridge, Kiskadee Trail offers even the casual hiker an opportunity for a close-up view of several native shrubs and trees and possibly a variety of birds.

Mesquite Trail

(1½ mile) starts at the Visitor Center parking lot. Trees shade portions of the trail as it winds through grassy savannas. Two small ponds located along the trail hold water in wet years. Signs of deer and coyote are evident along the trail.

Paisano Trail

(1 mile) is a remnant of the gunnery range located here during World War II. Verdin, roadrunner, long-billed thrasher, and plain chachalaca await the watchful birder. Our only paved trail, it is good in wet weather.

Lakside Trail

(1½ miles) starts at Osprey Overlook on the Laguna Atascosa. Views of the lake and thorn forest provide the possibility of good birding. Wildflowers are plentiful, especially during March and April.

Moranco Blanco

(3 1/10 miles) starts a short distance past Redhead Ridge on Bayside Drive. Moranco Blanco is a primitive route with good views of the bay and yucca in bloom (spring).

Alligator Pond

Alligator watching has become very popular at the refuge. During wet years they seem to inhabit every pond. Alligator Pond, .25 miles south of Osprey Overlook, usually has a gator or two. Alligators can also sometimes be seen on the resaca on Lakeside Drive. Alligators can be dangerous; stay on the road and do not feed or disturb them. Keep a close eye on small children and pets.
