Ostabat is a very beautiful, old place with narrow streets and only 285 inhabitants. It is located directly on the GR65 and is only one stage away from St-Jean-Pied-de-Port.
The GR65 leads directly past the Chapelle de Soyarza. Both the ascent and the descent are steep and rocky. But you will be rewarded with a very nice all-round view at an altitude of 290 m.
