Le Grammont hike above Lake Geneva

Medium hike (T2) | Superb views of Lake Geneva & the Rhône valley | Enjoy a drink or meal at Lac de Taney

Le Grammont dominates the skyline at the eastern end of Lake Geneva. Rising steeply above St-Gingolph on the southern shore, its summit offers a sweeping panorama up the Rhône valley, across to the Vaudois Pre-Alps, and right down the lake.

While steep in parts, the Le Grammont hike is not technically difficult and makes for a fabulous day walk in the Lake Geneva region.  The trail to the the summit starts at Lac de Taney — which itself is a very popular hike and the perfect place to stop for a picnic, drink or chalet meal along the way. The lake is accessible from a number of starting points. The trail described here starts from Le Flon; see “Other hiking options” below for alternatives.

Note that parking at Le Flon is difficult in summer; see our description of the Lac de Taney hike for parking details.

Getting there & away

Le Grammont is located at the south-eastern end of Lake Geneva, in the Swiss canton of Valais/Wallis near the border with France. It forms part of the Chablais mountain range — the Swiss section of the Savoy Alps.

The hiking trail described here starts from Le Flon, a small village above the town of Vouvry. The village is served by bus and has a car park; note that due to the popularity of the Lac de Taney hike, parking can fill very quickly. New parking measures were introduced in 2021; see our description of the Lac Taney hike for parking details.

What to bring

You don’t need any special equipment to do the Le Grammont hike in summer or early autumn. You will need snowshoes, skis or mountaineering gear when there’s a lot of snow. Whatever the season, be prepared for sudden changes in weather and take enough to eat and drink. You’re above the treeline after Lac de Taney so don’t forget sun protection.

Return Le Grammont hike from Le Flon

The trail to the Grammont summit is clear and well marked, with much of the way being a dirt road (T1). The last section to the summit is a mountain trail (T2). This section runs along the edge of a ridge with steep drop offs on the Lake Geneva side; be especially careful in misty, windy and/or wet conditions. Note that above Les Crosses there may be snow on the trail well into May and even June.

  • Height gain: 1,170 m
  • Trail level: T1 (road) or T2 (trail)

Follow the trail from the parking area at Le Flon, walking up either the steep hiking path or gravel road to the Col de Taney (or you can take a taxi!). Follow the road to and through Taney village, admiring the Lac de Taney as you pass its western end.  The road zig zags up to the Col des Crosses, with a fabulous view of the twin peaks of Les Jumelles along the way. The route flattens out for a while after the Col des Crosses, then becomes a mountain trail running up and along the ridge to the summit.

You’ll have precipitous views of Lake Geneva along this last section. Look down to see the Rhône River entering the lake; gaze across to Les Pléiades, the Tour d’Aï and other peaks in the Vaudois Pre-Alps; and enjoy the sweeping vista of the Rhône valley from the top of Le Grammont. Return the same way.
