This route was planned by komoot.
The primary starting point is Le Flon. You can reach Le Flon by public transport (postbus) from Aigle, or by car where parking is available. From Le Flon, you can hike up to Lac de Taney (about 1 hour 15 minutes with significant elevation gain) or take a taxi directly to the lake to begin the loop.
This trail is generally considered moderate to hard. It involves significant elevation gain (around 1,200 meters for the full loop) and steep sections, especially towards the summit. Good fitness, sure-footedness, and sturdy hiking shoes are essential. It's not recommended for absolute beginners.
The best time to undertake this hike is typically from June through October. During this period, the weather is generally more favorable, and the trail is clear of snow. Outside of these months, conditions can be challenging, especially at higher elevations.
While dogs are generally welcome on Swiss hiking trails, Lac de Taney is a protected nature reserve. This means there may be specific rules regarding dogs, especially concerning wildlife and amphibian breeding grounds. It's advisable to keep dogs on a leash, particularly around the lake and in sensitive areas, to protect the local flora and fauna.
No, there are no specific permits or entrance fees required to hike the Grammont from Lac de Taney loop trail. However, if you are driving to Le Flon, there may be parking fees.
The terrain varies. From Lac de Taney, you'll initially follow wide gravel paths through forests in long switchbacks. After leaving the forest, the path becomes steeper, maintaining its wide gravel character. The final half-hour push to the summit takes on a more alpine character, predominantly grass-covered but with steep sections and some loose rock, especially along the ridge. Good footwear and optional hiking poles are recommended.
The trail offers several stunning points of interest. You'll pass the idyllic Lac de Taney, a nature reserve. As you ascend, views open up to the distinctive twin peaks of "Les Jumelles" and the Rhone Valley. The summit of Grammont Summit (2,172 m) provides a spectacular 360-degree panorama, including Lake Geneva, the Savoy, Valais, and Bernese Alps, with Mont Blanc visible on clear days. You'll also pass L'Alamont if you take the loop extension, offering new perspectives over the Rhone Valley and the Dents du Midi.
Yes, at Lac de Taney, you'll find small chalets and restaurants, such as the Chalet du Lac de Taney, which offer a great spot for a break before or after your hike. These provide amenities and potentially accommodation options.
The Lac de Taney area is a protected nature reserve, known for its rich flora and as a breeding ground for amphibians. As you ascend, you might spot alpine wildflowers like alpine roses. Wildlife such as marmots and ibexes can sometimes be seen along the path, especially in the higher alpine sections.
Yes, the route intersects with and follows sections of several official trails. You'll find parts of the Sentier du Grammont, Chemin de Taney, Chemin de Peney, and Chemin des Prés. It also briefly touches sections of the 42-Alpine Passes Trail and 43-Alpine Passes Trail.
While the trail is challenging in either direction, some hikers find that ascending directly towards Grammont and then looping back via L'Alamont offers a more consistent climb. However, the final push to the summit is steep regardless of the approach. Always be prepared for a demanding hike.
A relaxed loop from Lac de Taney over the Alamont and Grammont. Beautiful views over Lake Geneva. The weather is already beginning to form an inversion, with a fantastic view of a sea of clouds.
