This is an easy excursion to arrive to the refuge, perfectly marked with red and white lines. From Ulldeter refuge you should walk up to the Marrana pass following the GR-11 path. Once you are on the top, you should walk to the South going down the bucolic Freser valley, where maybe you will observe the funny marmots, o the acrobatic chemois. This itinerary is the best one to arrive to the refuge during winter.
