The hike starts from the car park on the RD 91, where you will also find the "Lac des Mesches" stop on the Zest bus no. 23.
(S) From the RD 91, after a last glance at Lac des Mesches, look for post no. 82 located halfway between the dam and the hydroelectric centre.
(1) Take the path that winds its way up towards Vallon de la Minière.
(2) Continue along the wide path that leads into Vallon de la Minière.
(3) Do not cross the valley; stay on the same bank, climbing up to the left.
(4) At marker no. 87, continue to the left towards the Vallée des Merveilles.
(5) At marker no. 88, take the "path" option on the right, not the "track" which is much longer.
(6) Continue to follow the yellow markings on the right bank of the stream.
(7) Enter the Mercantour National Park (dogs are not allowed, even on a leash).
(8) At marker no. 89b, you still have the choice of climbing to the Refuge des Merveilles "by the path". Choose this option by continuing straight ahead, rather than "by the track" on the left.
(9) Continue climbing up the path, which is well equipped with steps, on a steeper section.
(10) At marker no. 90, the path joins the track, which you will follow to the Refuge.
(11) Enter the Vallée des Merveilles petroglyph area (spiked walking sticks prohibited).
The refuge can be seen in the last few metres of the hike.
(E) Arrival at the Refuge des Merveilles
