Simon Canyon Area of Critical Environmental Concern (ACEC) is about 3,900 acres in size and is managed for semi-primitive forms of recreation including fishing, hiking, and backpacking. Development at the mouth of the canyon is minimal (with a parking lot, picnic table, and toilet) and provides the visitor an alternative to the more highly developed state park sites located nearby.
The diverse canyon landscape provides habitat for a variety of bird and mammal species such as the golden eagle, prairie falcon, great horned owl, porcupine, beaver, and deer. Local sportsmen and fishing enthusiasts from across the United States come to fish the Quality Waters of the San Juan River, including the stretch that flows past the mouth of Simon Canyon. Narrow trails winding along the river's edge will lead you to your favorite fishing spot.
The canyon also contains remnants of an earlier human occupation. Simon Canyon Pueblito, a Navajo Pueblito that sits on a bench overlooking the canyon drainage. In addition, several minor arches can be found within the canyon.
