Climb sweeping mountain cols engineered through UNESCO-protected limestone ranges. Hammer the switchbacks of the MA-2141 into the rocky amphitheatre of Sa Calobra and climb back out on a relentless 7% gradient. Two days, 220 kilometres, and 4,500 vertical metres of smooth Balearic asphalt.
Arrive at Palma de Mallorca Airport (PMI) on Friday afternoon. Take a 35-minute taxi or express bus north to Port de Pollença or Sóller. Pick up a reserved carbon-fibre endurance road bike with Shimano Di2 or SRAM AXS gearing from a specialist rental fleet. Dial in your saddle height, bolt on your personal pedals, sync your head unit, and turn in early.
Saturday starts at 07:15 with the flagship route: The Sa Calobra Loop. Roll out towards the base of Coll de Femenia, climb steadily into the high limestone plateau past Lluc Monastery, and reach the aqueduct at Gorg Blau. Cross through the rock archway at the top of Coll dels Reis and descend the 10-kilometre serpentine road to the sea at Sa Calobra. Stop at the water edge, turn your machine around immediately, and climb the 9.5 kilometres at 7.1% average gradient. Return via Coll de la Batalla, logging 115 kilometres and 2,400 metres of climbing.
Sunday takes you across the Cap de Formentor out-and-back spur or south along the coastal balconies through Deià to Valldemossa. The Formentor road rolls over jagged cliff edges with views across Alcúdia Bay. Complete your 75-kilometre spin by 14:00, return the rental bike, wash up, and head to PMI for an evening return flight.
| Col Designation | Distance | Elevation Gain | Average Gradient | Maximum Pitch |
|---|---|---|---|---|
| Coll dels Reis (from Sa Calobra) | 9.5 km | 670 m | 7.1% | 14.0% |
| Puig Major (from Sóller) | 14.2 km | 840 m | 5.9% | 10.5% |
| Coll de Femenia (from Pollença) | 7.1 km | 405 m | 5.7% | 9.0% |
| Coll de Sóller (South face) | 4.9 km | 250 m | 5.1% | 8.5% |
Do not let bravado dictate your chainring ratios. Climbing consecutive Spanish mountain cols over back-to-back days will overload your lower back and knee joints if you grind heavy gears at 60 RPM. Modern professional road teams train in Mallorca with compact or semi-compact setups that promote smooth cadence.
Ensure your rental bike runs a 50/34 compact or 52/36 semi-compact chainset paired to a 11-34T or 10-33T 12-speed cassette. Having a true 1:1 gear ratio lets you spin comfortably at 85-90 RPM on the steepest switchbacks past the famous Nus de Sa Corbata (tie knot loop).
Mallorca's mountain tarmac offers immense grip when dry, but mountain moisture or olive tree dust can create slick conditions. Run 28mm or 30mm tubeless tyres at 65-75 PSI. Hydraulic disc brakes with 160mm rotors front and rear are non-negotiable for controlled braking on 70 km/h descents.
Sa Calobra is a dead-end road leading to a popular coastal tourist gorge. Between 10:30 and 15:30 in peak months, full-sized tour coaches squeeze around hairpin corners with zero margin for error. If you descend after 10:00, you will find yourself trapped behind bus exhaust or forced to brake hard mid-corner. Drop down the descent by 08:30 to own the road in clean morning sunlight with zero traffic interference.
