Fort Saint-Antoine car park
Preamble: this route has been marked almost entirely with turquoise blue dots, which you should follow as there are many paths not shown on the map. For the rest, the OpenStreetMap Randonnée map is the most suitable.
(S/E) Look for a blue dot in the car park near the gate to the lowest basin and take the path.
Continue straight ahead, following the blue markings. Further on, leave the path on the right and continue straight ahead.
(1) Turn right onto the path that climbs steeply.
(2) Variation marked by two blue dots for a round trip of about 20 minutes to see a geological curiosity: a rock with a hole in it. Beautiful panoramic view.
(3) When you reach the ramparts, follow the blue markings on the right.
(4) Take the steep rocky pass called "Passage Hugues", still following the blue markings. Before heading back down, you can stroll along the left to the Tour Beaumont viewpoint (Liberation Memorial, which is open to visitors).
(5) Take the path that descends below the road on the left from the cable car (magnificent view from there).
(6) Cross the tarmac road and follow the "Fort Saint-Antoine" path marked in yellow with a few blue markers where necessary.
(7) Turn right and head to the fascinating Tour de l'Ubac tower (which you can skip if you want to shorten the route). The sign says 1 hour, but the round trip actually takes 40 minutes. Otherwise, turn left towards the finish (S/E).
