The Costeplane Waterfalls

Site classified by decree of 9 January 1939.
Facing the Pas-de-la-Tour ravine, in the heart of a magnificent mountain environment, this natural curiosity is clearly visible from the road at the bottom of the valley. These waterfalls are a popular spot for panoramic views. They can also be explored from the village of Lauzet, along pleasant country trails.

Description of the walk

The walk starts in the village of Lauzet. Park in the car park on Place de la Mairie, behind the church.

(S/E) Leave the car park by going up Rue du Pied du Village in the opposite direction to the village square, which you will leave behind you. Follow this street to leave the village in the direction of the cemetery, which you will reach in the same direction (west) after passing a stable on your right. As you pass, take a look at the encouraging motto inscribed on the pediment of the cemetery gate.
Continue along this road. At the crossroads, turn right and join the old railway line (which has never seen a train) that runs alongside the road on the left.

(1) Take the left-hand track (signposted "tunnels"), which is well shaded, along the impressive railway walls. When you reach a wider clearing, leave the track (at the dead-end sign; do not go as far as the tunnel that you can see) and go down to your left to pass through a small tunnel under the track, which will take you back to the road you left earlier. This road will naturally lead you to the bridge that crosses the Ubaye at a place called Le Moulin. Follow this road, which passes between the two mill houses (recognisable by their millstones).

(2) Just above the tall house, take the path that leaves the tarmac road on the left. This path joins the road further up. Follow it uphill to the left until you reach a ford just below the waterfalls.

(3) From the ford, walk up along the stream to see the falls, which can be tricky with children. The path sometimes passes very close to the falls. A lovely spot for a picnic! Continue climbing up the right bank of the waterfalls to reach the road leading from Costeplane to Champcontier. Walk through old abandoned meadows (abandoned for farming due to the slope) to reach the tarmac road above.

(4) Turn right onto the road that descends towards the hamlet of Costeplane.

(5) At the entrance to the hamlet, the path passes under the houses. Go around the small shed on the right as you enter the hamlet, cross a wooden terrace and go down the steps to rejoin the path. The terrace is built on the communal path, so don't hesitate, you are definitely on the communal path! Walk along the village, passing the old school on your left, then the wash house and the chapel. Join the road further down which descends to the medieval bridge known as the "Roman bridge".

(6) Cross the Ubaye canyon via the Roman bridge and head back up towards the village via the path on your right.

(7) Return to the village entrance and head back to the car park via Rue d'en Haut on the left, crossing via one of the three cobbled alleyways. Return to the street you started on to get back to the starting point (S/E).

Worth a visit

The Costeplane Waterfalls:

Their distinctive feature is the system of groundwater flow on a slope of limestone concretions. Limestone tufa (travertine) is a stratified concretion deposited by an encrusting spring, also known as a petrifying spring. The tufa formation sometimes encloses residual voids (caves). It can also enclose vegetation debris (leaves, branches, trunks) as it progresses, leaving visible traces once the vegetation has decomposed.
At the top of the village of Lauzet, you can see a donkey tether, sealed into the wall of a house, made of travertine.
The Costeplane Waterfalls are located in the Blache ravine and are a remarkable and very popular canyoning site.

The Roman Bridge: Listed site since 1938

Listed as a Historic Monument by decree of 3 November 1987.
The so-called Roman bridge crosses the Ubaye on the road from Lauzet to Costeplane. 22.7 m long and 3.5 m wide, it is supported by a 9 m span ogival arch, which is 40 m above the torrent, making it one of the highest bridges of its time. Of rustic construction, it must be medieval (14th century, but the DIREN gives a broader date range, between the 12th and 15th centuries). It underwent repairs in 1881 and partially collapsed in 1902. Further repairs were carried out in 1975.
It is listed as a historic monument, along with its surroundings, as Roman by mistake. The bridge and its surroundings have been a listed site since 1938.

Its history:
Although known as Roman, this bridge is in fact Romanesque. It provided a link between Boscodon Abbey and Laverq. These two places of worship were part of the Chalaisian abbey complex. According to the Rule of Saint Benedict, the Chalaisian monks lived apart from the world and did not integrate into parish life. Thefirst monks were hermits who settled in Chalais (Voreppe, foothills of the Grande Chartreuse, Isère) in 1101 by the Bishop of Grenoble. They devoted themselves to forestry work and sheep farming.
To consolidate a small community that had settled in Boscodon in 1132, the Bishop of Embrun decided to build an abbey there in 1142 and to join forces with the monks of Chalais. This marked the birth of the Chalaisian order.
Sheep farming forced the monks to practise transhumance, and so several abbeys and priories joined the order in order to establish places of residence no more than a (long) day's walk apart.
There were 10 abbeys: Albeval, Almeval, Notre-Dame de Boscodon, Notre-Dame de Chalais, Clairecombe, Clausonne, Notre-Dame de Lure, Prads, Pierredon, and Valbonne, and 3 priories: Laverq, Paillerol, and Valserres.
The Order of Chalais was eventually absorbed by the Carthusian Order at the beginning of the 13th century.
So we can imagine the herds of the Chalais monks migrating between Boscodon and Laverq, crossing the "Roman" bridge at Lauzet 900 years ago!

A pleasant hike, even if the return journey is along a road that is very quiet at this time of year.

A pleasant little walk, fairly shaded on the way up. However, the descent is almost entirely on a small, quiet tarmac road (we didn't see any cars).
Beautiful view of the waterfall on the way up.

Pretty waterfalls provide welcome stops on the way up, followed by a return trip along a quiet little road.

Once you've passed the waterfalls, there are no signposts, which is a shame. We had to search around to find a way to a beautiful picnic spot above the waterfall, where children can swim. Then the climb back up to the 'normal' route and the return loop was a bit tough. I found this hike quite difficult in places, so I would recommend taking walking sticks.

hike completed the day after heavy rain, breathtaking route on the way up, quite technical for those lacking flexibility, superb waterfalls, the descent by road is relaxing and offers beautiful views, highly recommended and to be repeated as soon as possible

The loop is only interesting in its first part, after the beautiful waterfalls and the climb back up to the road. The return trip is uninteresting, consisting of road after road until you reach the Roman bridge.

We lost our way and found the trail again thanks to other hikers who had a connection and could use the app. They were also lost. We had climbed too high along the stream. The intersection to rejoin the road was not signposted.

A beautiful hike that is not to be missed.
Don't hesitate to get your feet wet to admire the waterfall. (Be careful, the water is extremely cold, even in August, but it's refreshing.)
Follow the stream upstream, but be careful, as crossing the abandoned meadows can be a bit tricky. This mistake led us to discover an unexpected waterfall (a little gem) and a welcome dip in the hot weather (31°C)
Take the small road back down to Costeplane and then YACA, following the directions on VISORANDO.

The climb up alongside the waterfalls is a bit tough and the path isn't very easy to find, but you get there in the end. However, the entire loop is about 1 km longer than indicated on the route. The return trip by road is a bit long but downhill and with a splendid panoramic view, so it's not unpleasant. Definitely worth doing!

Magnificent waterfalls!
The return trip on the paved road is rather unremarkable.
If we were to do it again, we wouldn't take the paved road but would go back down the path we took on the way up.
Magnificent site.

The hike starts at the car park opposite the lake and crosses the village on foot.
A pleasant and very accessible route with several viewpoints of these beautiful waterfalls.
Canyoning on the descent from the waterfalls.
There was a slight difficulty with navigation between points 3 and 4 as we may have stayed on a path too close to the waterfalls. We therefore had to take another fairly steep path to find the route indicated at point 4.
Picnic near the stream at the bridge over it for the return trip.
The return to the paved road is a bit long, but fortunately broken up by a small path near the hamlet. No cars until the Roman bridge. Very beautiful view of the valley.
Hikers usually stop at the top of the waterfalls, so it's busy up to that point but quiet after that.
