The La Leсa WSA is characterized by deep arroyos, highly sculpted mesas, canyons, and sandstone and shale outcrops. This area is easily traveled by horseback. Nesting sites for golden eagles, prairie falcon, great horned owl, red-tailed hawk, and raven are found on sandstone cliffs. Vegetation includes grama grass, cactus and Knight's milevetch. The Continental Divide National Scenic Trail passes through this WSA.
From Highway 550, approximately 18 miles north of San Ysidro, turn west on County Road 279. Continue about 17 miles; past the village of San Luis the road turns to dirt. As the road bends to the south, turn right on a side road and drive approximately Ѕ mile to where the Continental Divide National Scenic Trail crosses the road. There is no trailhead, and the trail is marked by cairns. Hike north into the WSA.
