At 2,444 meters, Hiru Erregen Mahaia (or Mesa de los Tres Reyes) is the absolute highest spot in Navarre and a total classic in the Pyrenees. Fun local legend says the old kings of Navarre, Aragon, and Béarn used to meet up right at the top so they could chat without stepping foot into each other's countries!

Just after leaving the parking lot, about 300 meters away, take the detour to the left and follow the path very easily and beautifully. If you have decent binoculars, you can see some chicks in the vulture colonies, depending on the time of year, and some adults all year round. Highly recommended, short and sweet.

Burgui is the start in the lower or southern part of the Roncal Valley, which ends in Belagua, at the foot of Piedra de San Martín. It is a very beautiful and quiet town, with all kinds of services to stay for several days and use it as a starting point for the various bike tours in the area. It is also highly recommended to reach Burgui via the road coming from Salvatierra de Esca, following the course of the Esca river through the Foz de Esca.

This place is full of trash, very dirty, a disgrace!!! The Basque mountains are not trash cans, please respect them. Too many people are behaving badly towards the pastures. Please take your trash back with you; it's disgusting and disrespectful.

There is very little shade on the entire circular route, only the last, short section in the gorge has shade. In summer it can get as hot as 40 degrees Celsius and then only the section in the gorge is recommended, not the circular hike.
