Riding Passo Giau

As the ride begins on the SP638, the Codalonga river runs adjacent to the climb as you begin your ascent. In this area, there’s also shaded cover provided by trees, making for a gentle start to the climb.

One unique feature about Passo Giau is that all the climbs corners are numbered, allowing you to know exactly how long you have left, or how far you have to go! Because there are 29 corners, the route can feel incredibly tight and the twisty layout of the climb offers you views of where you have previously been.

As you approach the summit of the climb, there is a long left-hand hairpin (number 24) that provides spectacular views of the climb below and adding to the drama of the finish after a tough ascent. Once you complete turn 24, Mount Nuvolau comes in to view and the ascent begins a 10% gradient for a tough final push. At the top, there is a hotel with restaurant that provides a good opportunity for rest, refreshment and reflection.
