From Tortosa, in the Erbre Valley, head towards Roquetes, where the ascent begins heading westwards along a winding road that reaches the El Mascar plateau. At a pass, ignore the road leading left towards the summit and continue across the wooded plateau to the Caro Refuge and the L’Esquirol car park.
(S/E) Continue along the road towards Fredes; it descends slightly. Ignore the road on the right leading to the Ermita de Santa Maria dels Ports and turn left to climb up to the Col de la Carrasqueta.
(1) Leave the road and take the signposted path (GR®) on the left, which climbs in stages through the forest and ends with a slightly steeper ascent to reach the Col dels Pallers, on the ridge.
(2) Turn left and continue climbing along the ridge, skirting round the first rocky outcrop on the left. The path then becomes steeper as it climbs to the first ledge, at an altitude of around 1,300 m. You’ll need to use your hands a little, but it’s never really exposed. The path becomes easier from there until you reach the next summit on the ridge: Moleta Redona.
(3) The summit of Caro is in sight, but you need to descend a little to an unnamed pass. The ridge then becomes very rocky; the path veers off to the west on the left, descending a small slope to reach a more passable, albeit steep, ramp. This ascent takes you to the base of the summit. By traversing to the left, you reach the road where the cyclists arrive.
(4) Explore the accessible parts of the summit: a monument and, above all, a panoramic esplanade overlooking the Ebro Valley.
(5) Return to the road (4) and begin the descent along a well-marked path, which cuts across the road’s hairpin bends, down to the Col del Vicari.
(6) The path veers to the left, cuts across a hairpin bend, then descends due north down fairly steep wooded slopes until it reaches the El Mascar road.
(7) Turn left and follow the more or less level road towards the Caro UEC refuge.
(8) At a Fork in the road, keep left (ignore the turn-off on the right to the Refugio Monte Caro). Continue to the L’Esquirol car park (S/E).
