The Lacs de Vens from Le Pra

A magnificent hike in the Haute-Tinée offering varied panoramas and one of the most beautiful series of lakes in the Mercantour!

The climb from Le Pra is gradual and easy, with the Cime de la Bonnette behind you. You then pass under the strange Aiguilles de Tortisse before arriving at the Col du Fer (view of Mont Viso).

After the Collet de Tortisse, you arrive at the arch, where you can enjoy a splendid panorama of the Lacs de Vens and the peaks of the Trou de l'Âne!

Description of the walk

The departure point is in the hamlet of Pra, which is now closed to traffic (see practical information).

(S) Start at marker 32 (1,670 m) at the edge of the RM64 road. Follow the yellow-marked trail that gradually winds its way up the left bank of the Tinée. You will quickly overlook the hamlet and the view opens up onto the Cime de la Bonnette to the west and Mont Mounier to the south.

(1) After about 45 minutes, you will arrive at a grassy area. Cross a stream on the right and enter the forest at the Plateau de Morgon, which is not exactly flat! Continue along the marked trail to reach marker 33.

(2) Continue straight ahead towards the Maisons Forestières de Tortisse. After a short descent, climb gradually back up to the houses (2,250 m) after crossing another stream. From the forest houses, you can see the strangely shaped Aiguilles de Tortisse just in front of the Cime du Fer. Go around them on the left to begin the ascent.

(3) The loop begins here, at marker 34, just behind the forest houses. Turn left towards the Col du Fer. Cross the previous stream again and climb gradually up the south-facing slope.
The slope becomes steeper as you get closer to the peaks and the pass. Enjoy the view behind you with a small unnamed lake on your right.

(4) After crossing a small snowfield, you arrive at the Col du Fer (border, 2,584 m), which overlooks the Ferriere Valley (logical), where many Italians climb. In the distance, due north, Mont Viso stands out clearly against the landscape. Continue the hike south towards the Lacs de Vens. Be careful, there may be snow in this area at the beginning of the season.

(5) After 5 minutes, you arrive at the Collet de Tortisse (2,591 m) facing the Cimes de Vens. You may see ibex in this area (below the peaks). You cannot see the lakes yet, but you are almost there.
Continue straight ahead (south) towards the lakes. There are marmots here. After 5-10 minutes, there is a natural arch on your left... and the Lacs de Vens on your right. There is a superb panorama with the six lakes in succession (you can actually see three of them, as some are very small compared to the upper lake). Continue the descent to the refuge (turn left onto a path marked in the last bend).

(6) Take a well-deserved break at the Refuge de Vens (2,366 m) to fill your water bottle or recharge your batteries (I recommend the blueberry tart) with a beautiful view of the lake and the peaks of the Trou de l'Âne in the background! Set off again on the path that arrives behind the refuge, then turn immediately left and cross the stream on the footbridge. Continue straight ahead (slightly to the right) at marker 25 to reach marker 24.

(7) At marker 24, turn left towards the Maisons Forestières de Tortisse. You will overlook the upper lake until you reach a small pass (marker 23).

(8) Keep going right in the same direction. The trail goes over the Vens valley. You'll quickly reach the Maisons Forestières de Tortisse.

(3) Continue straight ahead along the path you took on the way up to reach Le Pra (S/E).

Notes

1.5 to 2 litres of water should be sufficient. Water bottles can be refilled at the Refuge de Vens.

Walking poles may be useful at the start of the season (June) to cross the snowfields near the Col du Fer.

Protect yourself from the sun, as there is little shade along the route!

Parking: a municipal by-law (issued by the town hall of Saint-Dalmas-le-Selvage) prohibits access to the hamlet of Le Pra and parking along the RM 64 due to the risk of rockfalls and torrential floods. It is advisable to park downstream (in the commune of Saint-Étienne-de-Tinée) or upstream towards Bousiéyas and reach the starting point by carefully following the road.

This route passes through a protected area, which may be subject to special regulations:

Worth a visit

Wild animals: marmots, chamois, ibex, etc., but they are rare when there are many people around. If you want to see them, avoid weekends!

A very beautiful hike at this time of year.
Beautiful scenery.
Beautiful autumn colours and even snow.
Few hikers. Quite varied.
A minor drawback at times were the difficult passages because the wooden bridges to cross were missing and had not been installed.

Magnificent route.
We parked at the car park 500m above the waterfall (1.5 km of road to get to the start just before the hamlet of Le Pra) and then descended through the valley of the torrent de Vens from (8) direct to the same car park.
There was a bit of snow below the Col du Fer, but with good shoes and poles, we were able to get through it!

Wonderful hike 😍 Breathtakingly beautiful nature. Arrival at the lakes via the Col du Fer with a panoramic view of the Italian Alps. Good gradual elevation gain.
Park in the car park about 800 m before signpost 32 at the start.
Delicious blueberry tart at the refuge with homemade drinks. The rest... will be your discovery, filling your eyes and your heart with wonder

Magnificent hike with a modification to the route that allows you to walk along two lakes, but this increases the distance and duration, and therefore the difficulty.

I left from the car park at the Vens waterfall to avoid the Pra area, which was closed to parking due to rockfalls (several vehicles were parked there nonetheless). A beautiful climb with constant views of the very pretty Vens torrent and its series of waterfalls. I came out at the lakes via the chimney (on the right at the fork towards the lakes, leaving the path to the refuge on the left). There was a short, slightly steeper section but I didn't need to use my hands. I then climbed up alongside the lakes to the refuge, which I left on my right to climb up to the Col de Fer, where I was treated to a magnificent view of Mount Viso. Picnic break at the Aiguilles de Tortisse and descent (on the same side to see the lakes again, as the Tortisse valley seemed too austere and required either coming out at Le Pra or climbing back up behind the peaks) with a superb view of the string of lakes in their half-grass, half-rock cocoon. No one else had started the climb at 7 a.m., we met about twenty people on the way down, and the walk took a total of 7.5 hours. The road via the Col de la Bonnette to reach this walk is very beautiful, probably because it is part of the Tour de France cycle route. This walk will remain one of my fondest memories of the landscape (waterfalls and lakes).

A very beautiful hike, relatively long but still doable in a day, or else by stopping at the eponymous refuge.
Few animals to be seen, probably a little too busy in August... But the scenery is magnificent!!!

hello,
I know this route very well (I do it at least once a year!), but I think it's a shame that to save a few steps you leave out the Morgon lakes
At the start, take Salso Moreno, Vallon de la Cabane, the lakes, Pas de Morgon, Col du Fer... refuge...lacs de Vens, markers 27, 22 and 23, 34, and there you have a "real loop"
I'm not an alien, I'm always with a mixed and varied group (OVS website)... and we do it in a day! Sunday is a rest day and Monday is back to work...
Give it a try....

Clear and precise description for a superb hike.

Staying overnight at the refuge allows you to enjoy the site at sunset and sunrise.

Parking requires making a choice... It's great that you pointed this out.

Thank you again for sharing your experience!
