Sommet du Santin - Serre Orel

Sommet du Santin - Serre Orel is a modest, grass-covered summit rising directly above the Col du Lautaret, one of the best-known mountain passes in the French Hautes-Alpes. Administratively part of the commune of Villar-d'Arêne and sitting right on the edge of the Écrins massif, the peak reaches only 2,137 metres — far short of the giants around it — yet its short approach and prime position next to the road make it one of the most visited viewpoints in the area.

Where is Serre Orel and how do you get there?

The summit stands right beside the Col du Lautaret, the pass linking the Romanche valley with the Guisane valley at roughly 2,058 metres. Most visitors start from the pass itself, where a small summer visitor infrastructure exists, including the Ski Légende activity centre. Serre Orel rises on the opposite side of the road from the car park, clearly visible as soon as you step out of the vehicle.

What does the climb involve?

This is about as gentle as mountain walking gets in the Écrins region. The elevation gain is only around 150 metres, and most people complete the round trip in about two hours, faster if reasonably fit. There is no marked path up the slope — walkers simply head straight up the grassy incline toward the small stone cairn that marks the top, visible from a distance. Because of this simplicity, the outing is often recommended as a first taste of high-mountain walking, suitable for families and for visitors without technical hiking experience.

What can you see from the top?

Despite its modest altitude, Serre Orel delivers a surprisingly wide panorama. From the summit, the view sweeps across the Col du Lautaret itself and the ranges surrounding it: the Cerces massif to the north, the Arves massif toward Savoie, and the much higher, glaciated peaks of the Écrins massif to the south. That contrast — gentle green pastureland on one side, snow-capped Écrins summits on the other — is what gives this short walk its outsized reward.

What else is worth visiting nearby?

Less than a kilometre northwest of the summit, on the same side of the pass, sits the Lautaret Alpine Garden, one of France's oldest and most extensive collections of high-mountain plants, maintained by researchers from nearby scientific stations. Combining the short climb to Serre Orel with a visit to the garden makes for a natural half-day outing, particularly in summer when the alpine flora is at its most colourful. The commune of Villar-d'Arêne itself sits at the gateway to the Écrins National Park, making it a convenient base for longer excursions deeper into the massif.
