Planning your trip to Cuesta del Obispo

The Cuesta del Obispo is part of Provincial Route 33. It connects the Lerma Valley with the high-altitude Calchaquí Valleys. You will experience a massive change in scenery. The road begins in a green forest known as the Yungas. It quickly turns into a dusty, winding mountain pass.

The elevation gain is significant over a short distance. You will climb from 1,200 meters to over 3,300 meters. Check weather forecasts on the Salta official site before leaving. Heavy rain in summer can make the gravel sections slippery. Winters are dry but can be very cold at the summit.

Before you depart, ensure your vehicle is in top condition. Fuel up in Salta city as there are few stations on the way. You should also carry plenty of water and snacks. The landscape is remote, and services are limited until you reach Cachi.

• Checklist for the drive:
• Full tank of fuel.
• Physical map or offline GPS.
• Spare tire and jack.
• Warm layers for the summit.
• Water and coca leaves for altitude.

How to drive the Cuesta del Obispo road step-by-step

Following a set sequence ensures you don't miss the best viewpoints. The drive requires focus due to sharp curves and steep drops. Always stay on your side of the road, even if it feels narrow. Use your engine to brake on the way down to avoid overheating pads.

1. Step 1: Rent a vehicle in Salta. Pick up your car at the airport or downtown. Choose a car with good ground clearance for the gravel sections. Typical cost: $60–$100 USD per day. Time: 45 minutes for paperwork. Common mistake: Forgetting to check the condition of the spare tire.
2. Step 2: Drive to El Carril. Follow Route 68 south from Salta for about 45 kilometers. This section is paved and flat. Time: 1 hour. Common mistake: Not filling the fuel tank here before turning onto Route 33.
3. Step 3: Ascend the Cuesta. Turn onto Route 33 and begin the climb. The road becomes a series of switchbacks with incredible views of the Enchanted Valley. Time: 1.5 hours. Common mistake: Stopping in narrow curves for photos instead of designated pull-outs.
4. Step 4: Reach Piedra del Molino. This is the highest point at 3,348 meters. You will find a small chapel and a panoramic view. Time: 20 minutes for a break. Common mistake: Exerting yourself too much; the thin air can cause dizziness.
5. Step 5: Continue through Los Cardones. The road flattens out through the National Park. You will see thousands of giant cacti against the mountain backdrop. Time: 1 hour. Common mistake: Driving too fast on the long straight road known as Tin Tin Straight.

Choosing your transport: Car vs. Tour

Deciding whether to drive yourself or book a tour depends on your comfort level. A self-drive gives you total control over your schedule. You can spend more time at the summit or stop in small villages. This is the best option for photographers and independent travelers.

If you choose to drive, read our Cachi village travel guide for arrival tips. However, the road is challenging for nervous drivers. Hiring a professional driver allows you to enjoy the views without stress. Many tours leave from Salta daily and include lunch in Cachi.

Consider the "If X, do Y" logic: If you have more than two people and enjoy mountain roads, rent a car. If you are a solo traveler or want to learn about local history, take a guided tour.

Driving safety and troubleshooting tips

Safety is the priority on these high-altitude Andean routes. The road is partly paved and partly well-maintained gravel. However, rocks can occasionally fall onto the path during shifts in temperature. Always keep your headlights on for visibility in dust or fog.

Altitude sickness is a real concern for many visitors. Drink plenty of water and avoid heavy meals before the climb. Chewing coca leaves is a local remedy that helps with oxygen levels. If you feel very sick, descend to a lower elevation immediately.

• Troubleshooting common problems:
• Engine overheating: Stop in a safe place and let the car idle.
• Flat tire: Move as far off the road as possible before changing.
• Thick fog: Slow down significantly and follow the white lines.
• Brake fade: Stop for 15 minutes to let the brakes cool down.
• Road closures: Check status via local police or tourist offices.
• Running low on fuel: Payada and Cachi are the only reliable spots.
• GPS failure: Download offline maps as cell signal drops quickly.
