The Citadel car parks are located very close to the start (they are pay-and-display). Head towards the terrace (viewpoint) situated at the bend. The start is on the right at the end of the cul-de-sac.
(S/E) A wooden sign marks the start, a few metres above the famous Mare a Mare hiking trail in the Tavignanu valley. The walk begins with an initial climb up the ridge to a small stone cottage called A Casetta (approximately 300m of ascent over 1 km).
(1) At Casetta, a short break gives you the chance to enjoy a lovely view of Corte. Continue along the path to the right, crossing the hillside to begin a second climb up the path formed by a few rocky slabs. After a short flat section, pass the chestnut trees to begin the third climb, keeping to the left beneath the pine trees, towards the Col de la Croix.
(2) Col de la Croix (1,112 m); the cross is visible on the left. A lovely view over the peaks of La Punta Latiniccia (on the left) towards Monte Rotondu. Below, the entire ridge line stretches from the Alzu plateau to the Pointe de Zurmulu. Continue along the path to the right until you reach the fourth ascent.
(3) Begin a short climb (less than 100 m), which is quite steep but not exposed to a drop-off, sometimes requiring you to use your hands to steady yourself. Once you reach the flat section, go past the rocks and continue along the path to the right until you reach the climb up to the “Bâton”.
(4) You’ll reach the foot of the fifth (steep) climb towards the “Bâton”. Reach the small pass known as “le Bâton” (at an altitude of 1,400 m).
(5) The path then descends for a few metres before gradually climbing again towards the Arch. You can see the majestic arch, carved by nature into the granite, until you reach it.
(6) Continue along the path for a few metres to take some lovely photos. The return journey follows the same route as the outward journey (S/E).
