Three Crowns: Muganix - Irumugarrieta- Txurrumurru

A round trip to the first two summits of the Three Crowns, plus a third as a preamble.
For the less adventurous, the climb to Txurrumurru requires crossing a rocky bar that can be tricky.
Nevertheless, it's worth the effort to reach the narrow passage between two boulders that gives a view of Lake Endara.
Going to the last summit, Erroilbide, is much trickier and requires experience, which is why it is not mentioned in this itinerary.
