The climb to La Bastille is not to be missed, but neither are the less busy singletrack paths that you'll follow from the top. Over the valley and Belledonne mountains, they offer stunning views stretching all the way to Mont Blanc.
As you leave the "Relais de Rochebise" woods, you'll come to a cabin and, a few tens of metres further, the highest point of the itinerary, the "Bec Aigu". The descent offers a worthy technical challenge and requires caution on some of the steeper sections.
You'll find water at Porte Saint Laurent, Pied du Glacis and La Tronche Mairie
The calculation of the difficulty of each course takes into account the length, the positive vertical drop, the greatest continuous positive or negative vertical drop as well as the technicality of the terrain.
