Navárniz is at the foot of Mount Iluntzar. It stands at around 360 meters above sea level, making it high enough to have great views of the valley and mountains. It is a beautiful little town that is a good place to start an excursion.

This is a terrific trail that is quite easy to follow. It is especially nice in spring when the flowers come out. It gets a bit wild in the summer when the vegetation is waist high, but that's part of the adventure!
