FAQ
When is the best time to climb Sa Calobra?
From June to September, when the Alpine passes are clear of snow. Always check seasonal openings and any tolls before heading out.
What gearing do I need for Sa Calobra?
An average gradient of 7% calls for easy gearing: a compact crankset and a wide cassette. On ramps beyond 15% even strong riders appreciate a 34x32 or easier.
What's the steepest section of Sa Calobra?
The steepest ramp hits 12%, almost double the average gradient (7%): over 9.5 km total, that's where the climb is won or lost. Keep something in reserve for it.
