The Grotto and Hunter Line Shack

The Grotto and Hunter Line Shack is a 7-mile out-and-back on the McKittrick Canyon Trail. From McKittrick Canyon Trailhead, it follows the canyon to the open-faced Grotto, then a short way farther to the Hunter Line Shack before returning on the same path. Give it three to five hours. It is moderate because of the distance, not a big climb: the route gains less than 600 feet. Choose it when you want to walk deep into the canyon and stop for lunch. If you only have a few hours, Pratt Cabin is the shorter 4.8-mile turnaround. The Notch is a separate, longer hike with a much steeper finish.

Start at McKittrick Canyon Contact Station and follow the main canyon trail. The lower stretch is broad and covered with bright white gravel. It crosses dry washes and stays relatively open, with views toward Wilderness Ridge and little tree cover. The climb is gradual, but those first miles can feel sunny. Around mile 2, a signed side route leads to Pratt Cabin, about 2.4 miles from the start. The 7-mile figure follows the main route to the Grotto and shack and back; exploring the cabin adds a little more walking. Past the Pratt spur, the path narrows to dirt singletrack with rocky patches as the canyon closes in and brings more shade. Any creek crossings vary with water conditions.

The Grotto is a small, open-faced cave with rock benches and stone picnic tables in deep shade. A short, rocky drop leaves the main trail for the Grotto, then you climb back up and continue a few minutes to Hunter Line Shack. This is the natural lunch stop, not a developed cave or indoor attraction. For a photo, include the stone seating with the cave opening so the picture shows the place people come to rest, not just a dark patch of rock. The trail gets much steeper and rougher beyond here on the way to The Notch; that climb belongs to the longer hike, not this turnaround.

Hunter Line Shack is a weathered remnant of a 1920s ranching operation. The shack recalls the Hunter and Grisham partnership, which consolidated smaller West Texas ranches into a large corporate operation in the early 20th century. It is a simple building at the end of a long canyon walk, but it gives the route a human story alongside the Grotto and the landscape.

McKittrick Canyon is known for its late October fall color, when deciduous trees bring red, yellow, and brown against the pale rock and desert vegetation. The exact peak moves from year to year, so treat the timing as a seasonal chance, not a guarantee. Mule deer, squirrels, and rabbits live along the canyon route, though a sighting is never promised.

The route starts at McKittrick Canyon Contact Station. The parking lot and restrooms are by the station, and the trail begins across from the lot, beyond the building. The canyon is for day use; its entrance gate closes, so check the posted hours and allow enough time to be back before it locks. No reservation is listed for this day hike, though the park entrance fee applies. Pets are not allowed on trails. The exposed first miles and the full 7-mile distance are the main strain; there is more shade deeper in the canyon, but the walk still takes half a day.
