Walk to Lake Adus

This short walk, mainly through the forest, will take you to a pretty little mountain lake (2,130 m).
It's a good warm-up or an easy goal that can be done with children who are good walkers (be warned, it's still in the mountains, so... it's uphill).

Description of the walk

(1) From the car park just before the information boards, take the path that descends towards the stream.
Cross it via the footbridge, then follow the path (marked in yellow) which climbs gently through the forest for 800 metres and then becomes much steeper. A sign indicates "Lac des Adus 1h45".

(2) At marker 396, head straight towards the refuge, pass it and stay on the left-hand path at marker 395. The lake is not far away.

(3) For the return journey, ignore a path on the left, cross to the other side of the lake, head towards the refuge keeping to the right, then descend via the same route as on the way up.

I wouldn't call this hike a stroll because it's very steep, haha! However, the climb is worth it. Be careful not to follow the GR trail, otherwise you'll end up climbing the pass

A very pleasant hike that is not particularly difficult, even if the climb is sometimes a little tough as it is steady all the way to the lake.
The trail is never problematic and most of the climb is in the woods, making it ideal in summer when the sun is beating down. The path is sometimes steep but not excessively so, with two cables to provide reassurance on narrow sections.
The trail is lined with blueberries and there is a private refuge at the top of the climb with a water pipe accessible to all outside.
The landscape of larch trees and blueberry bushes is splendid, both on the way up and around the lake.
However, there are a lot of mosquitoes! Mosquito repellent and a tent are essential if you plan to camp.

A very interesting walk, mainly through woodland. The arrival at Lake Adus is very pleasant, as is the landscape around it, even though, unfortunately, we did most of the route in drizzly Norman weather (or Breton weather, so as not to offend anyone). Be warned, however, that some sections are very steep.
PLEASE NOTE - If, like us, you only have your smartphone to guide you, remember to download the information sheet. You will lose your Internet connection almost as soon as you set off. This is not a major problem as the route is fairly obvious and well signposted.

A short, easy and very pleasant hike.
The trail is always clear, well marked and never problematic. Sometimes steep but not excessively so.
I am very surprised to see comments about the vertiginous nature of the route. There is a very small section with two cables installed over a few metres, but these are mainly for reassurance, as there are no real difficulties. Personally, I did not use them.
The refuge's fountain is accessible and can be a welcome relief so you don't have to carry too much.
From two-thirds of the way along the route, the landscape of larch trees and blueberry bushes is splendid, as is the area around the lake.
The only downside is that the flies and mosquitoes are very intrusive! Mosquito repellent and a tent are highly recommended (if not mandatory) if you are camping (in accordance with national park rules).

The trail starts off pleasantly in the undergrowth, then becomes very steep and narrow, not recommended if you suffer from vertigo or are with inexperienced children. The path seems to have changed since Storm Alex? For our part, we did not complete the trail due to vertigo.

Thank you for clarifying that. I have just added it to the description for future reference.
Kind regards

Hello,
Yes, Bibi, it is indeed because there is no warning that the route is very steep that I rated the description as "moderate". We also came across several hikers who were avoiding taking it. It is known as the most direct route to Lake Adus. Have a nice day.

Thank you for your feedback. However, you mention that the description is "average". Where exactly could it be improved? For the section that climbs quite steeply?
Kind regards

Hello,
The route described from the Salèse car park to Lake Adus is quite accurate, except that after the footbridge, the path climbs gently through the forest, but this is short-lived as it quickly becomes a very steep climb over rocks. We made the climb in about 1 hour 45 minutes, as indicated on the signpost at the start. This little lake is very pretty – no sign of mosquitoes at the end of May – with patches of snow still clinging to the ground. However, we descended via the Col de Salèse (via marker 437). Between marker 437 and the Col de Salèse, we descended through snow – very soft at this time of year – and our boots got completely covered! This route is obviously longer but so much easier and prettier, covered with rhododendrons that will soon be in bloom. Then Col de Salèse - Salèse car park and, for those of us without a car, on to Boréon and finally Saint-Martin Vésubie. A long but very beautiful day (departure at 8.30am and arrival at 7pm) ... despite our age (69 and 71).

This walk is very enjoyable, mainly through shaded woodland, which is welcome on hot days.
Perhaps the description should mention that some sections are narrow and not recommended for people who are prone to vertigo.

The climb is not easy and not suitable for children.
A very pleasant walk in summer as there is plenty of undergrowth.
It is not advisable to swim in this lake, where herds of cows come to drink and bathe, as we observed on 21 July 2015.

We preferred to continue via the Col de Salèse and descend via the GR 52 in the Salèse valley so as not to take the same route back, which made the walk a little longer than planned.

Thank you for recommending this beautiful hike.
