Piedra del Molino: Highest Point of Cuesta del Obispo

Piedra del Molino sits at 3,367 meters (11,046 feet) above sea level, the highest point of the Cuesta del Obispo climb on Provincial Route 33. This rocky pass marks the eastern entrance to Los Cardones National Park, about 100 kilometers from Salta city — roughly a 2-hour drive. A large granite millstone gave the spot its name; legend says it was hauled up by truck in 1927, split under its own weight, and abandoned when the owners never returned. Today it's a 15- to 20-minute photo stop with a small chapel, local vendors, and sweeping views over the Quebrada de Escoipe.

Getting There and the Drive Itself

The Route from Salta

From Salta, drive south on RN-68 for about 50 kilometers to the town of El Carril. Turn west (right) onto RP-33 and begin the climb through the Quebrada de Escoipe. The road ascends for roughly 20 kilometers of tight, cornice-edge curves before reaching Piedra del Molino. The full distance from Salta is about 100 kilometers to the park's eastern boundary. The drive takes around 2 hours without stops, but every switchback invites a pause.

The road is paved but narrow in sections, with few guardrails. If you're driving yourself, start early — morning light on the ochre slopes is excellent, and traffic is lighter before 10 a.m. I'd avoid the return trip after dark; fog can settle quickly on the upper switchbacks, and the drop-offs are real.

Parking and Facilities at the Pass

There's a gravel parking area large enough for a few cars and a bus or two. No entrance fee is charged at Piedra del Molino itself — it's a free roadside stop. You'll find a small chapel (Capilla San Rafael), a stone mill wheel, and several information signs. Local vendors sell goat cheese, honey, llama salami, and ponchos — bring small bills. There are no restrooms or drinking water, so plan accordingly.

Organized Tours vs. Self-Drive

Most visitors arrive on day tours from Salta (full-day Cachi or Cafayate combos). Tours typically allot 15 minutes here, which is enough for photos but tight if you want to walk the short trail behind the chapel. Self-drive gives you the freedom to linger, but you'll need to handle the altitude and curves yourself. Rental cars are available in Salta; a standard sedan handles the paved route fine.

What to See and Do at Piedra del Molino

The Millstone and the Chapel

The namesake millstone lies split in two beside the road — a granite disc roughly 1.5 meters across. It's not dramatic, but the story gives the place character. The whitewashed Capilla San Rafael, a tiny chapel with a pitched roof, sits just behind it. Both make for quick, distinctive photos. Stick a sticker on the signboard if you've brought one; it's a local tradition.

Panoramic Views

On clear days, the view stretches across the Quebrada de Escoipe and the Valle Encantado. The landscape shifts abruptly here: below is the green, folded valley; above and west lies the arid puna that leads into Los Cardones. Clouds often roll in by midday, sometimes creating the illusion that the viewpoint is floating. For the sharpest visibility, aim for a morning arrival between April and November.

Short Walks and Altitude

The pass is the trailhead for a short climb up a nearby hill (around 3,474 meters at the summit, class 2 scramble). It takes 30–45 minutes round trip. At this elevation, walk slowly — dizziness is common. I'd skip the scramble if you're not acclimatized to the altitude; the views from the parking area are already expansive.

Local Vendors

A handful of vendors set up tables near the chapel, selling goat cheese, honey, cured meats, and woven goods. It's a good place to buy a snack for the road ahead — the cheese is tangy and fresh, and prices are reasonable. Cash only.

Practical Details and Tips

Best Time to Visit

The park's dry season runs from April to November, with clear skies and cooler temperatures. December to April brings more cloud cover (which can be atmospheric) but also summer rains that may make roads impassable. Check weather forecasts before setting out; if rain is forecast, delay your trip.

Altitude and Health

At 3,367 meters, altitude sickness can affect some visitors. Symptoms include headache, shortness of breath, and dizziness. Drink water, move slowly, and don't overexert. If you're coming from Salta (1,200 meters), the ascent is rapid — take breaks on the drive up.

Piedra del Molino is open 24/7 and free to visit. Los Cardones National Park itself is also free, but park gates are open daily 09:30–18:00. Fees are subject to change — check the official site for current rates. No reservation is needed.
