Park in the Fort de la Revère car park and admire the breathtaking Mediterranean coastline.
(S/E) From the car park, head towards the nearby Fort de la Revère, its esplanade and its orientation table. Then walk along this fortified structure, dating from 1870 and in perfect condition. Follow the tarmac road downhill. After about a hundred metres, turn right, following the sign for "maison de la nature" (nature centre).
Go down the stairs. Pass marker 652: the Maison de la Nature, which is well worth a visit, is in front of you. After your visit, take a look at the karstic cave of Simboula on your left, then go down to the crossroads at marker 641.
(1) Turn left onto the D.F.C.I track and immediately turn right at the wooden sign for the "sentier botanique" (botanical trail). This trail winds through the forest for about 300 metres before reaching a V-shaped intersection: continue to the right to reach a scree slope with a cairn.
(2) Turn left and then, after a few dozen metres, left again at the next trail intersection. Continue along the wooded trail, keeping to the right at the next V-shaped crossroads. Join a D.F.C.I. track at a bend.
(3) Turn left and continue to the intersection at marker 640. Turn right and continue along this track, which continues to climb. At this point, the noise from the A8 motorway is unpleasant, but the views of the Tercier plateau and the Alps are remarkable.
(4) In the left-hand bend in the track, turn right onto the forest path that runs along the north side of the fire water reservoir. Continue to a clearing, staying along the slope. A large pylon appears and serves as a landmark. Pass to the right of the pylon and continue towards a nearby house used by the farmers working in the Departmental Park. From this building, you can see a fortification to the west. This fort, occupied by the Parsec Astrorama association, offers a simple and accessible introduction to astronomy and space for all.
(5) Look for the path on the right, which will be the return route, and continue straight on to the Astrorama. Go to the western corner of the fortification.
(6) Take the stony forest path that starts here. You will come to a crossroads with a cairn and, on the left, a moat where the walls of the 1870 fortifications are still visible.
(7) Turn right onto this flat path which continues along the hillside until you reach a wooden sign from another era indicating "Astrorama 10 min". Turn right and climb a few metres up the path to arrive not far from the farmers' house seen earlier.
(5) Turn left and then immediately right to pass behind the pylon on the south side this time and follow the track that leads to the pylon towards Route de la Révère. Once you reach it, turn left and, to avoid traffic, walk through the woods parallel to the road for about 200 metres.
At the track closed by a barrier, turn left for about 50 metres and then turn right onto the return path: if you reach the beehives, you have missed the path and must turn back. When you reach a track, turn right onto it and return to the car park (S/E).
