After breakfast, it closes for a while for cleaning. Fill up your water bottle before heading up, as it's a scarce resource up there.

The Mesa de los Tres Reyes is the highest peak in Navarra with 2444 meters. It starts from the Linza refuge, being a hard and demanding climb due to the distance (17 km round trip) and the difference in altitude (1309 meters); and the last climb to reach the top in which you inevitably have to put your hands down on a steep slope with loose stones, although it is even more impressive on the way down. But the effort is rewarded by the areas that are crossed and the views throughout the journey.
