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.
(D) 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.

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...

During the walk or to do/see around
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).

La Grande Jumelle
Starting point in Vouvry (Valais)
A not too busy hike up to a summit offering a vast panoramic view. A relatively challenging route with some aerial passages requesting a certain sense of itinerary at times. The beginning of the hikes passes through Tanay site and its lake.
Starting point in Leysin (Vaud)
The Tours d'Aï and Mayen are twin peaks visible from afar. The Tour d'AÏ is slightly higher than its neighbour, and also visited more frequently. It's a progressive climb which offers an aerial tour at the very end. Amazing views of Lac Léman, le Chablais, les Dents du Midi and the Mont Blanc massif from the summit.
Tour de Mayen
Starting point in Leysin (Vaud)
The Tours d'Aï and Mayen are twin peaks visible from afar. The Tour de Mayen is slightly lower than its neighbour, not as busy and provides a more wilderness setting. The climb is progressive with two stages, the Chalets de Mayen and Segray Lake. Just beneath the summit, a very clear view of Lac Léman, les Diablerets, le Chablais, les dents du Midi and the Mont Blanc Massif.
Tête de Chalin
Starting point in Monthey (Valais)
An uphill hike taking you to the foot of the Eastern Peak (Cime de l'Est), eastern peninsular of "les Dents du Midi", with mind-blowing mountain view points and a panoramic view extending towards the Vaudois Alps. A challenging itinerary with a short aerial path through ridges.
Mont Ouzon, views of Lac Leman, Chablais & Mont Blanc Massifs
Starting point in Le Biot (74 - Haute-Savoie)
Starting in the abandoned ski resort of Drouzin le Mont in Col du Corbier, this is a moderate mountain climb winding through a forest section & alpine meadows before concluding with a short but challenging craggy rock face. The summit is sheltered by large rocks offering 360 stunning views of Lac Leman to the North and Mont Blanc to the South. It is not for the faint hearted, solo inexperienced or novice if a vertical rock scramble is not your thing, but the rest of hike is far more moderate.

Starting point in Montriond (74 - Haute-Savoie)
A there and back hike up to Roc de Taveneuse with views across to Abondance.
