Three Peaks of Lavaredo

The Tre Cime di Lavaredo are one of the most recognizable symbols of the Alps-three Dolomite towers rising vertically over 2900 meters in the heart of the Tre Cime Nature Park, in the UNESCO site of the Dolomites. The Cima Grande, the highest of the three at 2999 meters, is also one of the most famous rock faces in the mountaineering world. At that altitude, the air contains 69% of the oxygen of sea level - an altitude at which most healthy people do not experience significant difficulty, but which is felt during the steepest sections. The great peculiarity of this destination is that the classic experience - the circuit around the three towers - takes place at altitudes between 2320m and 2454m, where oxygen is about 74%. Reaching the summit of the Cima Grande, on the other hand, requires specific mountaineering equipment and skills.

Route

Summary

The most popular route is the classic circuit that goes around the three peaks via Forcella Lavaredo, Rifugio Locatelli and Rifugio Lavaredo, returning to the starting point. It is a loop on a well-marked trail, accessible to hikers with good physical fitness, with no technical difficulties. The normal route to Cima Grande (2999m) is a completely different itinerary: it requires climbing skills up to UIAA grade III, harness, helmet and rope. The two routes are aimed at different audiences and should not be confused.

Classic circuit (loop, ~10 km)

Auronzo Refuge (2320m - 0 km) Rifugio Auronzo can be reached by car from Misurina by driving along the toll road (tollroad) to the parking lot. It is the starting point for almost all visitors and the place where any equipment is rented. The facility is very busy in high season: we recommend arriving by 8:00 a.m. to find parking.

Forcella Lavaredo (2454m - 2.0 km) Follow trail No. 101 west-northwest to Forcella Lavaredo, the pass between Cima Piccola and Cima Grande. It is the highest point of the classic circuit and the most iconic for photography: the three towers stand out imposingly to the north. The panorama sweeps from Cadore to the Sexten Dolomites. It is also home to the Lavaredo Refuge (2344m), located a few dozen meters below the fork on the southern slope.

Rifugio Locatelli / Dreizinnenhütte (2405m - 5.0 km) Continuing northwest along Trail No. 101, you round the northern slope of the three peaks and reach the Locatelli Refuge (2405m). This is the most famous vantage point: from here the three peaks can be seen in their classic profile, with Cima Grande in the center, flanked by Cima Occidentale and Cima Piccola. The refuge offers refreshments and, with reservations, overnight lodging. The section from Locatelli eastward along Trail No. 105 completes the loop to the Auronzo Refuge.

Rifugio Lavaredo (2344m - 8.0 km) Closing the loop from the southern slope, you pass the Lavaredo Refuge again before returning to the Auronzo Refuge. The trail is well marked and frequented.

Normal route to Cima Grande (2999m - mountaineering variant).

The normal route to the Cima Grande traverses the south face for about 250 meters of climbing height difference (III UIAA). It requires harness, helmet, rope, climbing shoes or hard boots and the ability to move roped up on vertical rock. It is not a via ferrata: progression is on small rocks with natural protection. The additional time compared to reaching the base of the wall is about 2-3 hours for the ascent and 1.5-2 hours for the descent (rappelling). Do not tackle this variant without documented mountaineering experience and preferably with a guide.

Practical notes.

• Access: toll road from Misurina (Auronzo di Cadore). Check parking availability in high season (July-August). Alternatively, shuttle bus from Misurina during peak hours.
• Frequency: the circuit is one of the busiest in the Dolomites. Leave early (by 8:00 am) to avoid the crowds and heat of the afternoon.
• Meteorology: weather forecasts in the Dolomite area change rapidly. Plan your descent by 2 p.m. to avoid frequent afternoon thunderstorms in July-August.
• Rifugio Locatelli: reservations required for overnight stays in high season.

⚠️ Please note: Trail conditions may vary depending on residual snow (June) and thunderstorms (August). Check the updated conditions on the Three Peaks Nature Park website or at the Auronzo Hut before departure. Do not approach the base of walls during precipitation or after periods of intense heat because of the risk of rock fall.

Oxygenation and Breathing

The Three Peaks of Lavaredo offer two very different high altitude experiences from an oxygenation perspective.

Classic circuit (2320-2454m): at this altitude the air contains 74% of the oxygen of sea level. Almost no healthy person experiences significant breathing difficulties. Exertion is felt on the uphill sections, but an average trained hiker easily manages the four-hour circuit.

Cima Grande (2999m): at elevation 2999m oxygen drops to 69%. The difference from the circuit is perceptible: the last 500 meters of climbing elevation gain challenges even experienced climbers, and muscle recovery between pitches is slower than at lower elevation.

What to expect by elevation zone.

• 2320-2454m (circuit): fatigue proportional to physical effort. No significant hypoxia effect for healthy people.
• 2454-2999m (normal route Cima Grande): perceptible increase in exertion, more frequent breathing, slower recovery. Relevant mainly during climbing on vertical terrain.

Typical saturation (SpO₂).

At the summit of Cima Grande, a healthy, acclimatized person typically records a SpO₂ between 91% and 95%. At this altitude, values generally remain good; a drop below 88% with associated symptoms is a signal not to be ignored.

Tips for breath management.

1. No specific acclimatization needed for the circuit: those who ascend in the day from Misurina (1756m) run no hypoxia risk for the circuit alone.
2. For the normal route: if coming from low altitude, staying overnight in Misurina or at Rifugio Auronzo the night before facilitates adaptation.
3. Constant rhythm in climbing: on vertical pitches breathing tends to become restrained. Remember to breathe regularly even on challenging passages.
4. Hydration: even at 2400m water requirements increase compared to sea level. Bring at least 1.5 liters for the circuit.

Warning Signals (AMS).

⚠️ Consider descending if they appear:

• Persistent headache that does not improve with hydration
• Nausea or vomiting
• Fatigue disproportionate to exertion

Preparation

Physical preparation.

Good hiking preparation is sufficient for the classic circuit: ability to walk for 3-4 hours with a cumulative elevation gain of about 450 meters. No experience on rock or snow is required.

For the normal route to the Cima Grande, specific mountaineering preparation is essential: cliff climbing to at least UIAA grade IV as a reserve (the route is III but on rock that is not always excellent), roped progression, use of harness and helmet. The accompaniment of an IFMGA mountain guide is strongly recommended for those without documented experience on alpine rock routes.

Acclimatization.

For the circuit: no acclimatization plan required.

For the normal route to Cima Grande: overnight stay at Rifugio Auronzo (2320m) or Rifugio Locatelli (2405m) the night before is recommended for those coming from altitudes < 1000m.

Essential equipment (circuit)

• Hiking shoes with sturdy soles
• Waterproof layered clothing
• Water and food for the day (at least 1.5 liters)

Additional equipment (normal route Cima Grande).

• Harness, helmet, rope (30m minimum)
• Hard boots or climbing shoes
• Quickdraws and lanyards for protection

Frequently Asked Questions

How much oxygen is available at the Three Peaks of Lavaredo?

The classic circuit takes place between 2320m and 2454m, where available oxygen is about 74% above sea level. Those who reach the summit of the Cima Grande (2999m) find 69% oxygen. In both cases, for the vast majority of healthy people, hypoxia causes no significant difficulty.

Is it possible to reach the summit of Cima Grande without mountaineering equipment?

No. The normal route to the Cima Grande requires climbing up to UIAA grade III, harness, helmet and rope. There is no via ferrata that reaches the summit. The classic circuit, however, is accessible to any hiker with good hiking shoes.

Is there a risk of altitude sickness at the Three Peaks circuit?

The AMS risk at the circuit (max 2454m) is low for healthy people. Symptoms of AMS rarely appear below 2500m. Those who are very sensitive to altitude may experience mild headache or fatigue, but it usually resolves spontaneously.

When is the best time to visit the Three Peaks?

July and August guarantee a trail clear of residual snow and the most stable weather conditions. In June there may be snowy sections in the Fork area. September is splendid for color and fewer crowds, but afternoon thunderstorms remain frequent. Always check updated conditions before setting out.

How many people visit the Three Peaks each year?

The Three Peaks of Lavaredo are among the most visited Dolomite destinations with more than 700,000 annual passes. In high season (July-August) the area is very crowded: leaving by 8:00 am and paying attention to parking is essential.
