Le Grammont

Passing through Tanay preserved site, and its lake, you'll climb to the summit offering a unique view point over Lac Léman and a panoramic view over the surrounding mountains.
A busy hiking trail with steep slopes but without any technical difficulty.
N.B. The calculated height difference is over estimated, it's actually closer to 1000 metres.

Description of the walk

Parking available at the place called Le Flon's converted car-park at the top of Miex village. You can take Miex road from Vouvry, a commune located between Le Bouveret and Monthey.

(S) At the far end of the car-park, take the ‘‘chemin des chevriers’’ trail to the right heading towards Tanay (sometimes spelt Taney). Most of the time under forest cover, the trail heads upwards with a few bends sticking to an overall north-west direction. You'll come across a paved road which also leads up to Tanay. A bit further up, you'll find a road, take it to the left over a few metres leaving it at a turn and crossing over a small dip at the end of which you'll find the road again. Take the road to the left until you get to the pass which leads to Tanay.

(1) Stick to the road which heads slightly downhill with a beautiful view of Tanay Lake to the right-hand side. Once you reach the "heart" of the hamlet, you'll come across "Le Grammont" restaurant.

(2) Facing the restaurant, locate the beginning of a trail to the left leading to Grammont (sign). The trail passes behind the restaurant and winds up a series of turns through the forest. You'll come across a junction with an alpine track, take a hairpin turn to the right. Keep going through the forest coming out onto a pasture. The large trail keeps to a north-west direction towards Crosses chalet.

(3) Keep heading through pastures, on the large trail which winds up a steep slope. Reaching Crosses pass, at the foot of "la Petite Jumelle", you'll come across a distinctively shaped lime scale tower which is located to the west.

(4) Keep heading north along the relatively flat trail which loops around to the right heading through a steep passageway on the left called ‘‘Tombeau des Allemands"(German's Tomb). You'll come close to a long and narrow alpine chalet.

(5) Instead of approaching the chalet take a slight turn to the right along a trail heading up a steep, grassy rounded hilltop. The trail then takes a sharp turn left. Follow the south-east ridge line reaching the summit and its huge cross visible from afar.

(6) The trip back is the same way you came in on.

Practical information

Allow for 3 hours hike to the summit, without stops.

"Alternative" -- To get to Tanay, you can also take the paved road which starts near the car park (S) which the trail meets up with (see above). Vehicle access being strictly regulated, the road is not busy at all. The slope is steep weather you take the road or the trail.

Hiking gear and shoes a must.
Water available at Tanay, there's also food and refreshments and the opportunity to stay overnight.

A map is necessary (at least the one attached to this description). A compass is always handy...

In the nearby area

In the summer, you can swim in Tanay Lake as long as you can handle the low temperature, not above 15°... The lake can also be the highlight of the hike in its own right, you can walk all along it and there are multiple ideal picnic spots (allow for 3/4 to an hour for the climb from the car park).

Le Grammont overlooks the Lac Léman by nearly 1800 metres: you can enjoy a unique view point over the lake and the Rhône's river mouth. On the other side, a vast panoramic view over the Chablais summits, les Dents du Midi, les Diablerets and a bit further, the Grand Combin Mountain (Valais Alps).

A very nice walk.
The difficulty lies in its length, with a significant difference in altitude (1200 m), but the view of Lake Geneva is magnificent.
There is a parking charge of 1 Swiss franc per hour, to be paid on arrival at the car park.

Superb hike, with a recommended stop at Lac de Taney. Lac de Taney can be reached via the forest road instead of the footpath, which is less strenuous and takes the same amount of time.
The view from the summit is extraordinary, over the Swiss Alps, the Leman, the Valais and the Mont Blanc range.
The only drawback is the pay car park, which is expensive and limited in space, with no other parking options.

Exceptional walk!!!

Safe from start to finish. No risky spots, the 1100m climb is easy even if steep at the beginning and end.

Variety of panoramas!

At Grammont: the best 360° view I've seen of the Alps to date! And believe me, I've already explored it!

At weekends, they limit parking to the 80 spaces in the flon car park. It's impossible to park anywhere else (or even on the climb), so it's better to do it during the week.

A very pretty walk with no difficulties despite the difference in altitude. Beautiful panoramic views and the area is very busy.

Hiking in damp weather: drizzle and light rain.
Nevertheless, the little we saw was nice.
The climb was very easy; you didn't really feel the difference in altitude.
On the way back we took the Chemin des Crêtes, Allemont, which isn't very well marked: thanks to the GPS.
It's greener and more varied than the outward journey.

Superb views over Lake Geneva! Very busy, so plan to start as early as possible. The Grammont/Lac de Lovenex junction is unfortunately closed.

A very nice hike with views plunging down from the summit onto Lake Leman and the Valais.
The view from the binoculars is also very beautiful!

Very nice walk, not difficult, we met several children. The view of Lake Geneva is superb. It was very busy. Make sure you leave early, as the Flon car park was packed when we got back on Sunday afternoon, and there were lots of people at Lac de Taney too. On the way down from Grammont, we passed the summit of Alamont. The start of the path is well signposted on the track leading down from the Grammont to Taney. The path to the Alamont cross is well marked, then there is no path, just a barely marked trail. You need to be careful if you want to take this option on the way back.

A very nice walk, linked to the location of Tanay and its lake.
The route may be a little steep, but it's steady, so you can swallow the difference in altitude quickly.
Just under 1100m, for 14.7 km in 3 hours.

Very good route, fairly steep path to the Tanay lake, then white path to the foot of the Grammont, we covered 15.1 km A/R instead of the 12.02 km announced, difference in altitude 1200 and we took with the stops 7h30 including 2H30 of stop.
Magnificent weather and a 360° view, a must-do!
Not very difficult in good condition, with a stop at Lac de Tanay on the way up and a coffee and cake, and the same on the way back.

Well-marked route
