At the beginning of the route (actually the top of the 682m mountain), there is a spectacular corner that takes you around 270 degrees and back under the road that you have just ridden down.
Halfway down there is a junction - stay on the main road to the right for the ride down to sa Calobra where there are resting facilities, or take the turning to the left to climb over another hill and down to a small, deserted cove.
