Reach the Causse hamlet of La Bourgarie via the very narrow tarmac road that branches off to the right or left of the D16, depending on which direction you’re coming from. It’s very difficult for vehicles to pass each other along this stretch, so you must drive carefully. Once you arrive, park in the small car park signposted on the left: motorhomes are not permitted.
Yellow PR® signposts
(S/E) Leave the car park heading towards the houses, then turn left, walk past the lodge and continue to the end of the tarmac road, where there is a signpost indicating, amongst other things, the Cinglegros. Turn right onto the grassy path, which quickly becomes stony and descends diagonally, partly through the woodland. You’ll reach the junction marking the start of the Gaupillat path, which is not signposted on the ground.
No signposting
(1) Take the path on the right towards the Yellow Cross and the sign indicating that you are on private property but that passage is permitted; take care not to leave the path. Descend steeply along a series of hairpin bends before reaching the Pas de l’Arc, a magnificent natural arch carved into the rock by erosion.
(2) Pass through this magnificent arch, then continue down the path, which becomes somewhat indistinct for a few metres before becoming clearer again and veering sharply to the left as it runs along the hillside. The route then winds its way beneath pine and deciduous trees, more or less following the contour lines, whilst skirting the base of the impressive cliffs. Take care of the rocks and roots, which can easily cause you to lose your footing on this very little-used and therefore poorly maintained – or indeed unmaintained – path. Numerous unsecured viewing points offer breathtaking views of the Gorges du Tarn, both upstream and downstream. Reach the level of Combe Rousse and come to a junction marked by a sign indicating that you are entering a protected natural area.
(3) Keep to the path which continues to the right and walk for about a hundred metres to reach a junction that is easy to miss.
(4) It is very tempting to carry on straight towards the Tarn and the hamlet of La Sablière without paying attention to the path that starts on the left, marked by a single small rock serving as a cairn. So take the Sentier Gaupillat on the left, which becomes more rugged, with a succession of small rocky sections, both uphill and downhill, which can sometimes be tricky to navigate. Furthermore, the vegetation is taking over again and you often have to crouch down to squeeze through the branches of the shrubs lining the path, which is sometimes barely visible. You’ll reach a junction at the foot of a rock face, where it is difficult to find your bearings on the ground, especiallyearly in the season.
(5) To the left, a fairly easy climbing section about 3 to 4 metres high, leading to the foot of the cliff face, seems to offer a way to continue the route. This is not the case, however, as you must continue straight on through the tall grass,which completely obscures the path for a good ten metres: any tracks left by previous walkers will be a great help here. Then continue along the path, which becomes clearer again, until you reach a junction easily recognisable by the old pine trunk on the ground that partially blocks access.
(6) Head left and tackle the very steep and gruelling climb leading to the foot of the Cinglegros, where a sign indicates that you are entering a quiet zone for small animals. Ignore the path on the right leading there, as access to the ladders used to reach the summit is currently prohibited. Carry on straight ahead and climb up to the foot of the Pas des Trois Fondus, which isthe most challenging and difficult section of the walk.
(7) A series of metal rungs set into the rock enables you to cross this very steep rocky section, leading to the two ladders you must climb;the second of these, spanning the void for a few metres, is the most impressive and requires the utmost caution. There are then a few more metal rungs, followed by a final ladder, before continuing along the very steep path which quickly leads to the signposted Martel trail, which we had left behind when setting off from La Bourgarie.

(8) Turn left. The balcony-like path allows you to recover fromthe previous exertionswhilst offering splendid views over the Tarn valley. A few short uphill or downhill sections require you to use your hands. Continue to a crossroads.
(9) Ignore the path on the left, which runs flat and where a Yellow Cross advises against continuing in that direction. Take the path on the right for a very steep climb of a few dozen metres before reaching a flatter, easier section.
(10) It is difficult to spot the very narrow, steeply descending path here which leads off to the left towards the Baousso del Biel, a magnificent rock arch far more imposing than the Pas de l’Arc, standing 40 metres high – 25 metres of which are under the arch – and 25 metres wide. However, it is best to stickto the signposted path so thatyou can enjoy several breathtaking views of this natural wonder as you look back. Continue on to reach the start of the Gaupillat path.
(1) Head straight on, in the opposite direction to the way you came, to return to the hamlet of La Bourgarie and the car park at the start (S/E).
