Red-and-white markings
(S/E) Follow the track to the end, where you’ll reach a small concrete bridge spanning the Vallon de Valloar. Turn left to cross the stream and reach marker 73.
(1) Take the path that climbs to the right towards the Col de Gialorgues (signposted as a 2-hour walk, but it will certainly take you a little longer).
The path winds its way beneath the larch trees and between the various streams flowing down from the mountain. Then, as you emerge from the forest, you’ll approach the Vallon de Gialorgues, which you’ll follow until you reach La Sagne, a peatland at the foot of the Cime de la Gorgia.
Carry on to the right of the peatland and, after a short climb past the marmots’ burrows, you’ll reach the Refuge de Gialorgues at marker 73a.
(2) Carry on straight ahead towards the Col de Gialorgues. After a small hillock, the path winds gently upwards, overlooking a first pretty, unnamed lake, then a second lake at the foot of the Cime de Bolofré, the Lac de Privola.
Shortly afterwards, the Col de Gialorgues is near, but there is still a short, steep section to climb, which is easily managed via a few hairpin bends.
You’ll reach the pass at marker 279, where you’ll be treated to a lovely view of the Estrop, a hanging valley in the Haut-Var.
(3) Possible alternative route: from the pass, you can take an easy round trip to the Lacs de l’Estrop by following the unmarked path that branches off to the right. Allow about 30 minutes for the round trip.
Yellow markings
To continue the walk, turn left towards the Baisse de la Boulière. The path climbs gradually as it winds round the Rocher du Pigeon, and on your right you’ll see the lovely green-coloured Lac des Sagnos. When you reach the Baisse at marker 280, you’ll find an imposing giant looming before you: the Cime de Pal!
No signposting
(4) To climb to the Tête de la Boulière, take the start of the path that climbs to the right up the eastern slope of the mountain. Make your way gently up the grassy slopes a few dozen metres below the summit ridge. Then go round a scree slope on the right and reach a small grassy valley which will lead you onto the ridge, about a hundred metres from the summit. Follow the ridge to the summit, which is marked by a cairn.
(5) From the summit, the 360° panorama is magnificent: to your left, on the northern side, lies the entire Estrop valley with Las Sagnos, and higher up, the Estrop Lakes at the foot of the Sommet de Gialorgues. To the right, you can see the lower Lake Gialorgues and, above it, the peaks overlooking the Trou de l’Âne (Pointe du Trou, Pointe Côte de l’Âne and Fort Carra).
To the north-west lie Mont Pelat and the peaks of the Haut-Var; further west is the Trois Évêchés massif.
Due north, on a clear day, one can see Mont Viso, and to the east, the peaks of the eastern part of the Mercantour (between the Cime de Bolofré and the Cime de Pal).
To the south, you can make out the slopes of the Valberg ski resort and the peaks of the Cians.
After a well-deserved break, you can head back down by following the same route as on the way up to the starting point (S/E).
