Yan can also discover my previous trips on French long-walk tracks:
European walking route E2. This trail is famous for its route through the French Alps from Lake Geneva to Nice. the Alpine GR5 – 52, from north to south, as it crosses through the highest part of the French Alps, along the borders of Switzerland and Italy. Starting out from Lake Geneva, and ending up 620 km away (after 3-4 weeks of walking) on a Mediterranean beach…I means long ascents as you climb from the river valleys up to the high passes, and long descents as you hike down to the next big river. Passes traversed along the GR5 – GR52 are at 6,000 to 10,000 feet (1,800 – 3,000 meters), but the river valleys crossed can be as low as 1,500 to 3,000 feet (400 – 900 meters). These vast ups and downs mean not only that you will have a difficult walk, but also that you will traverse and see a great variety of beautiful scenery and different ecosystems—from pastures to woods to sub-alpine meadows, to glaciers. In the lower lands you will visit areas full of villages and life, while in the heights you can be completely remote from civilization. Brittany Coastal Path GR34:
The GR 10 is a French GR footpath, or hiking trail, that runs the length of the Pyrenees Mountains. It roughly parallels the French-Spanish border on the French side. Hiking the entire route is estimated to take around 52 days for hikers who are in good shape and used to mountain hiking. Some stretches involve a lot of ascending and descending, including a few one-day sections that can climb and then descend 1,200 metres (3,900 ft), but the GR 10 is a hiking trail, and there is no actual mountain climbing involved. The trail covers a distance of 866 kilometres (538 mi), with 48,000 metres (157,000 ft) of ascent.
The GR34 – or Sentier des Douaniers – is a trail for those who enjoy hiking on high cliffs, views of the ocean. The GR34 coastal footpath is based on the former coastguards’ beat in the 17th and 18th- centuries. Tea, tobacco, wine and spirits were regularly whisked across the Channel by smugglers to avoid England’s high import duties. The Sentier des Douaniers near Perros-Guirec is an easy way to view the Pink Granite coast with its impressive and strangely shaped rocks.
The GR54 trail circuit around the Écrins national park, the Tour of the Oisans. The route is known to be one of Europe’s toughest treks and traverses difficult terrain. The Tour of the Oisans covers a distance of 176km, crosses 14 passes, and ascends a total of 12,830m in 10 or 13 days. Several stages of the Oisans trek cross unprotected rocky sections, or follow narrow, exposed trails safeguarded by a fixed cable. Others slant across steep slopes of shale and grit and some of the cols are so narrow that you could sit astride the ridge with legs dangling on either side. The Tour of the Oisans is tougher and more demanding than most other multi-day treks in Europe, and although it is a walk that requires no technical mountaineering skills, scrambling ability, sure-footedness and a good head for heights will be called for. Most of the trails are clearly defined, straightforward and well maintained. But there are also numerous narrow and exposed sections on which great care should be exercised. Even the most undemanding paths can become hazardous when transformed by rain, snow or ice.
