Start your mountain bike adventure at Pontresina railway station and ride uphill towards the Bernina Pass. Take a break at the Morteratsch alpine cheese dairy and then fight your way up the climb to the back of Morteratsch. Follow the Bernina stream to Bernina Suot and then turn left into Val da Fain, where a breathtaking view of the Bernina massif and the Palü glaciers awaits you. Once you have reached Alp Stretta, enjoy the rewarding descent back to Pontresina.
