This is the longer and yes, the more difficult climb up to the summit of Coll de Sóller. The route starts from the the town of Sóller, heading south on the old road to Palma first on the Ma-11 then taking a sharp left onto the Ma-11A to continue on the old road to Palma away from the new tunnel where no bicycles are allowed.
Coll de Sóller from Sóller
A category 2 climb, with a total length of 7.4km and an average gradient of 6%. Starting at a height of 70m and topping out at 497m, your height gained is 427m via more hairpin bends than you can count (I tried, 26 I think - or 25 or 27!).
Is a relatively steady climb, and once you are a couple of kilometres in, the hairpin bends begin. Good luck with trying to count them, as there are just so many. The road twists and turns as you ascend, offering some spectacular views. This side of the mountain is more sheltered from the sun in the mornings, making it cooler.
On the descent, take care with the hairpins, they are easy to get caught out on especially with hot brakes towards the bottom where the camber of the bend may be slightly less than you need. If you descend towards Bunyola, that side of the mountain is more exposed to the sun.
The heatcan be a concern depending on the month you go as the climb is sheltered from the breeze in places. A special mention should be made of the café Ca'n Topa at the summit which has been there since 1880 under various guises.
