The HexaTrek is an epic long-distance hiking trail that crosses France from northeast to southwest via its most beautiful mountain ranges.

This Collection takes you through the heart of the Hautes-Alpes along the spellbinding third section of the HexaTrek. The route starts with a loop through the Écrins National Park, then climbs up to the Belledonne range and then descends through the Vercors High Plateaux nature reserve. This circuit of 565 kilometres (351 mi) and 28,300 metres (92,848 ft) of elevation gain finally makes a small incursion into the Provençal Baronnies before ending at the gates of the Ardèche Gorges. While the official route stops at Saint-Martin-d'Ardèche, I recommend crossing the bridge for a majestic arrival in the perched village of Aiguèze, hailed as the most beautiful village in France.

In this Collection, I divide this section of the HexaTrek into 35 stages, each averaging 20 kilometres (12 mi). This itinerary allows you to find accommodation almost every day. However, I suggest that you bring a tent and a sleeping bag to allow more flexibility. They’ll be necessary if you follow this Collection to the letter.

This long-distance trail is not marked. It sometimes follows the GR, sometimes the GRP or the black paths (secondary walking paths). Don't be surprised if you go off the GR and the beaten track at times. More often than not, this will be for the benefit of a spectacular climb or a viewpoint unknown to the ‘GRists’.

A departure in June or at the beginning of September will work in your favour during this great adventure. Indeed, these two months are less popular with summer holidaymakers. Also, you can be sure to arrive in the south at times when the temperatures are more moderate.

The official start of your HexaTrek is at the legendary Col du Lautaret. You can reach it by bus from Briançon or Grenoble by the LER 35 bus line. The timetable can be found on the Dauphiné website: dauphine.transdev.com/line/ler-35 (in French).

On arrival, you can walk to Saint-Martin-d'Ardèche and take a bus to Les Crozes or Pont-Saint-Esprit to catch a mainline bus or TER to major cities served by TGV.

If Hexatrek has piqued your curiosity, you can find the first two stages in my other Collections.

    Starting such an adventure in a place as mythical as the Lautaret pass is necessarily a harbinger of beautiful promises. And these are not long in coming since the path winds, from the start, around the nature reserve of the peaks of Combeynot. You will then see several 3,000 racing towards the sky.

    As if the Hexatrek were eager to take you to the heart of things, the route of this second stage goes straight south. Straight to the wild spaces of the Écrins.

    

    Some passages are very disturbing. In particular the section of the GR 54 which passes between the peaks of Pointe-des-Neyzets and Cucumelle

    You will enjoy this sixth step in many ways. First for its indulgent profile with a short 15 kilometers and only 60 meters of elevation gain. So certainly it will go down, but in a fairly rolling way. You can enjoy the landscape without thinking too much about the effort required.

    It's a short stage, barely 10 kilometers long, but more than compensated for by its 1,310 meters of elevation gain. In all, there are six uninterrupted kilometers of climb with passages at more than 30%. Courage !

    

    At the top you will be rewarded with magnificent views of the highest peaks of the Écrins

    With a tent you can consider shortening the stage. If you leave early in the morning, you will arrive at Lac de la Muzelle without

Where you will find everything to sleep, eat, refresh yourself and do your shopping. If you prefer to stick to the official

    From Venosc to Les Deux Alpes, the trail winds around the summit of Pied Moutet. I also suggest that you leave the main path and take a path that climbs to the summit, at 2,338 meters above sea level. A breathtaking 360° panorama awaits you up there.

    

    After that, you can descend quietly to the resort of

    This step requires you to be equipped with a tent. If you don't have one, it is recommended to double the stage with the next one to get to the Etendard refuge. But you have to keep in mind that it would represent a big day of 30 kilometers and 1,500 meters of elevation gain.

    This stage is rather rolling on the first two thirds. The vertical drop, ascending and descending, intensifies around the 12th kilometer. Save strength for the end.

    Do not be fooled by appearances. Behind the 15 kilometers and 1,000 meters of elevation gain displayed, it is a physical and technical stage. You will have two beautiful steep slopes (dry hills) to climb with sections exceeding 50%.
