Sa Calobra Classic

Mallorca route guide · Serra de Tramuntana

Riding Sa Calobra Classic

The famous serpent road: 26 hairpins down to the sea, through the rock gate, then the climb back home.

The mapped road is 10.5 km each way. Muntro carries it to the turnaround and back, so the complete ride is 20.9 km with 727 m of climbing.

The mountain character comes from more than gradient. Limestone, tunnel mouths, dry-stone edges, pine shade, reservoirs, and compressed hairpins change the view as much as the elevation.

Relief, gradient, and how to pace it

This is serious vertical terrain. The road spans 711 m from bottom to top and accumulates 727 m of ascent, with sampled ramps reaching 12.5%. The profile makes the pacing decision visible before the first pedal stroke.

Start conservatively and keep something in reserve for the final third. On a smart trainer the real gradient changes arrive exactly where the road changes, so a smooth power ceiling matters more than chasing speed on every ramp.

Points to watch for

The best Mallorca routes are remembered as a sequence of places, not as a GPX line. These are the changes of scene that organise this ride.

1. 01

   Coll dels Reis

   The road begins on the exposed 682-metre pass before tipping into the limestone amphitheatre.

2. 02

   Nus de sa Corbata

   The signature 270-degree tie-knot bend crosses over itself on a stone bridge.

3. 03

   The rock gate

   Near the bottom, the road squeezes through a cleft where the walls close over the rider.

4. 04

   Port de Sa Calobra

   Sea level is the turnaround. The only road home is the one you just descended.

Why this road works indoors

muntro does not flatten Sa Calobra Classic into a workout backdrop. The route’s bends, height, and junction order come from the road itself, while a compatible trainer reproduces the changing gradient under your pedals.

The turnaround matters: you learn the road in one direction, then read every slope and landmark differently on the way back.
