The dam route from Tarentaise

This hike will take you to the north face of the Pilat massif and the Mézenc plateau, with beautiful forest crossings. Enjoy the coolness of the two dams visited and climb a rock to admire the rugged landscape of the Gouffre d'Enfer.

Description of the walk

Departure from the village of Tarentaise from the car park near the church. Nearby, note the representation of Saturn.

(S/E) Head west for 50 metres on the D37, then turn right towards Les Chirouzes.

(1) At the fork, take the road on the right which climbs uphill and, after the houses, turns into a dirt track. Note the representations of Uranus and Neptune along this route. Enter the forest and you will come to a T-junction with a path coming from the right. Take the path on the left. The path curves to the right and then sharply to the left. You will reach a wider path leading to the houses of La Côte Des Pins.

(2) Do not head towards the houses, but take the hairpin bend to the right. 600 m further on, the path heads off to the left on flat ground, ignoring a path on the right that leads downhill. You will reach a track; follow this track on flat ground for 200 m.

(3) At the next junction, take the sharp right-hand bend downhill. The path reaches a tarmac section where you ignore the uphill section on the right and follow the left. Continue downhill before walking along the Riot dam. (For the record: it is on this section that work has been carried out requiring a change to the hiking trails).

Cross the retaining wall on the left. At the end of the dam, follow a path downhill to the right, curving first to the right and then to the left to reach the stream.

(4) Follow the path along the stream on the right. Pass a bridge crossing the stream on your right.
Note the remains of old dam gates on your right.

(5) Further on, cross back over to the right bank of the stream. Follow the dam on the right bank along a walkway, revealing a large pipe below on the right in what looks like a canal. Reach the rock overlooking the dam.

(6) Climb up and down the rock. Stairs lead to the top, where you can admire the landscape and sometimes see climbers on the neighbouring rocks.
Cross the dam's retaining wall and, at its end, follow a path uphill to the left.

(7) After 700 m, at an elevation of 854 m, ignore the path branching off to the right towards Planfoy and follow the path downhill to the left. The forest path leads to a car park and a junction with a road coming from the right.

(8) Follow the road downhill to reach the Riot dam and continue straight ahead without crossing the dam.
You will reach a familiar spot. Walk along the dam, then at its end cross the footbridge to find yourself climbing to the left of the stream. Continue for 3 km in a straight line along the stony track that leads to the D37 road at Pont Souvignet. Note the two enormous Douglas firs as you pass.

(9) Cross the road, continue straight ahead and cross the car park. At the end, cross the footbridge to the right of the stream and join a forest path. In the bend of the path to the right, cross the stream again to the left. Climb two bends, left then right, towards what looks like an old canal.

(10) Turn left, then almost immediately take the path, which is not very well marked, turns right slightly uphill then left downhill to cross a small stream. Go up to the right after crossing the stream and leave the forest. You will come to a large path with a tennis court on the right.

(11) Follow the path to the right along the edge of the forest, which is initially unpaved and then paved. Reach a road and follow it to the left for 50 metres, then turn right onto an uphill path crossing the meadows. Cross a path running north-east/south-west and follow the path opposite, which then becomes a road leading to the village. On this section, note the explanations about comets and dwarf planets. Reach a road and continue opposite towards the village. Head for the bell tower to return to the starting point (on the way, visit the wash house on the right) (S/E).

Notes

This hike, originally created in August 2015, has been redone here after work carried out on the Riot dam. It was removed from the catalogue at the end of August 2020 due to the modified route and is therefore being offered again after checks in the field. What is unique about August 2020 is that the Riot dam is full of water and the Gouffre d'Enfer only sees water passing at the foot of its reservoir!

There are no drinking water points despite the presence of two dams and streams.

Standard hiking equipment.

Worth a visit

The village of Tarentaise: church, wash house, buildings...
The planet route around Tarentaise: Original! Everything is described on educational panels opposite the church.
The two dams visited: The Riot dam is full of water, but the Gouffre d'Enfer dam is dry as of 29/08/2020.
The chaotic landscape of Gouffre d'Enfer with the surrounding climbing rocks. We recommend climbing the rock at the eastern end of the Gouffre d'Enfer dam to enjoy a beautiful view.

A pleasant hike with a slightly uphill second half, but without too much difficulty.
Rather than taking the tarmac road, sometimes take the paths above or below.

A beautiful route, sheltered from the wind, through light forests, no tarmac, no difficulty, beautiful landscapes
at Gouffre d'Enfer, at the end of the lake, take the time to admire the via ferrata and zip line on the side of the rock...
the second part of the route is easy, with a very gradual climb... worth doing again

A very pleasant walk during the week. The description is clear and the route is well marked, so there are no particular problems. We met a few people along the way and quite a few around the second lake, but it was lunchtime, so that explains it, and the weather was ideal for this outing.
Thank you to the author!

Done on a scorching hot day (but started early in the morning), the numerous passages through the woods provided us with much-needed shade. The climb up to the Rocher de l'Enfer is well worth the effort, as the view is superb.

A beautiful outing with many passages under trees that shelter you from the sun. The only tricky part is finding the right track on the way up to TARENTAISE, just off the educational trail of the old sawmill.

A very pleasant, shaded route with no difficulty and varied landscapes.
Note that between 2 and 3, the T-junction signposted has more than 3 options. Take the left-hand one.
It took us only 4.5 hours, without rushing and including a lunch break, to complete the circular.

A beautiful, pleasant route, but it's a shame that the sky was overcast until early afternoon.
We strayed from the route between 2 and 3, but found our way back at Pas du Riot.
