The Five Lakes of Forclaz

A lovely hike in the Beaufortain to discover the five lakes of Forclaz.
This is an easy route with no navigation difficulties, so you can leave your map in your bag.
At the start, you are still in the mountain pastures, then gradually the environment becomes more and more rocky.

Description of the walk

Reach Fort de la Platte above Bourg-Saint-Maurice at the end of a long road with a mixture of paved and dirt sections.
Park in the car park below the fort at an altitude of 1,890 m.

(S/E) From the start, signposts indicate the walking times for each of the five lakes.
Head back up the road towards the fort.

(1) Then head north-west along the track, which soon passes near an orientation table.
Continue climbing, still heading north-west, until you reach Grand Praz.

(2) After Grand Praz, turn right. The route is sometimes a farm track, sometimes a path, but it is well signposted. This will take you to the Col de Forclaz, where there are more signposts and the times to reach each of the five lakes.

(3) From the pass, the trail begins a descent to cross the Forclaz stream.

(4) Then climb back up towards Lac d'Esola.

(5) The trail then continues towards Lac Riondet and immediately after Lac Cornu.

(6) Go around Lac Cornu to reach the edge of Lac Verdet. These three lakes are grouped together.

(7) A final climb leads to Lac Noir at 2,532 metres.

(8) Return to the car park (S/E) by retracing your steps.

A lovely walk, not particularly technical, offering beautiful views of the Grande Sassière and Mont Pourri.
Actually, the trickiest bit is getting to the car park by car, as it’s difficult for vehicles to pass each other. But that’s just to give us something to talk about...
We highly recommend it!

The road up to the fort is partly tarmacked and easy to drive on the track. Be prepared for oncoming traffic going up and down. Please note: right of way goes to those going uphill, but not all drivers are equally capable of reversing 100 metres back to the previous refuge. A bit of common sense and a relaxed attitude are needed.
No need for a compass or map. Just follow the path. The climb to the pass above Lac Noir adds a few dozen metres, but the view of Mont Blanc is sublime, as is the view on the other side towards Mont Pourri. You can climb up to the turret-shaped observatory further up. In short, go for it and respect the lakes – they’re fragile.

To get to the GAEC car park, it’s best to have a vehicle with decent ground clearance. We managed it in a very low-slung Ford Focus, but it’s not ideal. The walk is really lovely, with some very pretty scenery. There are a few fairly steep sections, but they’re manageable even for occasional walkers like us.

Hello
I would like to make three observations about this hike
- Getting to the Platte Fort car park by car is no easy feat, but it is possible thanks to some improvements (tarmac on the bends) that have been made
- i would describe the hike as "moderate" in terms of difficulty due to the significant elevation gain (740 metres over 12 kilometres) recorded on my hiking software
-i recommend taking a look at the small cheese shop in the car park: they are producers who make their own cheese (goat and cow), which I found to be excellent
this hike is superb, with beautiful wild lakes surrounded by sharp-peaked mountains
Thanks to the route designer

This is an easy hike starting from Fort de la Platte, unlike the other one from Roselend, which passes through the Combe de la Nova and is dangerous. Here, there are no difficulties and not too many slopes either. The walk to the lakes is easy, and they are all very beautiful! Don't stop at the last lake, continue a little further towards the Col de la Nova, where you are likely to come across a herd of ibex. With a little patience and caution, it is possible to approach them discreetly. They will have spotted you, but as long as you keep a safe distance, they will not move and will let you observe them quietly. However, there is no point in trying to follow them if they decide to run away! A very beautiful hike!

A very beautiful hike, starting from the GAEC des 5 lacs car park (Fort de la Platte).
We climbed up with a herd of goats to the Col de la Forclaz, and then we entered sheep country.
The 5 lakes are magnificent, each with their own charm. As the weather was fine, we climbed above the Lac Noir on the ridges. What a view!
To reach the car park near the fort, take the small road called Les Echines. After the wooden cross, the road becomes a track for 2.5 km, but the bends are tarmacked, which makes for easier driving. Early in the morning, we only came across one other vehicle.
The GAEC farmers are very friendly and run a small refreshment stand where they sell their cheese.

A beautiful hike starting from Fort de la Platte

We weren't alone, but there's room for everyone!

Please note that to reach the Fort de la Platte car park (at the GAEC des 5 Lacs), it is best to take the road from Bourg St Maurice via Les Echines Dessous, then Les Echines Dessus, and finally the Route du Grand Replat. Your GPS may suggest (in theory, as a shorter route) going via Le Villaret, but the road is more uncertain and even complicated without a 4x4. In fact, in Le Villaret, there are signs advising you not to follow your GPS... (but without indicating the alternative route via Les Echines)

Access to the final car park may seem complicated. But it's still easy to drive. However, passing other vehicles can be tricky. But that's a minor inconvenience compared to this magnificent hike. As the car park is much lower down, the hike is long but easy. And so beautiful!

Superb hike. Magnificent landscapes. No difficulties apart from the car access, which was a bit chaotic at the end.

Plus, you can buy cheese when you arrive

Contrary to previous reviews, access to Fort La Platte is easy, and the road is perfectly passable, so there is no need to park before the road and walk an extra 6 km (there and back)!
A very beautiful hike with no particular difficulties.
A must-do!

Thanks for the clarification about the tarmac bends, which weren't tarmac before.

Superb hike, the lakes are magnificent. No technical difficulties (done with a 7 year old). It's well worth the climb to the ridge just above Lac Noir: a beautiful view of Mont Blanc. The road is impressive over the last two km, but it went without a hitch in a Citroën Berlingo. The road is passable and the bends are tarmac and fairly wide.

In reply to the review left by JFC73:
"As it's hardly possible to do this hike from the valley, if you don't have a suitable vehicle, it's best to look elsewhere ..."

It is possible to start the hike from the wooden cross, which is 4 km from Les Echines Dessus, which is what I did, not wanting to use my vehicle for the last part of the stony road to the Fort de la Platte.
An extra 45 minutes on the way up, less than 30 on the way down.
It is also possible to leave from the Les Echines Dessus car park and climb to the lakes via the Vallée des Sapieux and return via the Fort de la Platte and the Fort du Truc, which is an alternative for good walkers...
So there's absolutely no need to leave from the valley if you don't have a suitable vehicle, as you mentioned, as the road to Les Echines poses no problem, and the same goes for the wooden cross ...
