When you get to the top of the Carosello 3000 in San Rocco you will find the beginning of Coast to Coast on your right. It’s marked with an arch you have to bike through to begin. The trail is packed full of bends, jumps, and long flowy stretches. You finish up at the Livigno Central cable car. Here you can decide if you want to stop for a rest at the Costaccia Refuge, or if you’d prefer to continue to the valley floor along the Roller Coaster. The two trails combined make a great 10km adventure!
