Along the cliffs of the Abaddia reservation are some bunker ruins. On one of them, we find a compass rose. It was made in 1997 by a group of 15 year olds, at the beginning of the third millennium. The Domaine d 'Abbadia (Abbadia reserve), is part of the coastal trail, 25 km of routes linking Hendaye Bidart, along the cliffs. Being cautious, it is a great place to walk with children. You can do a route which will take approximately 2 hours between cliffs and bunkers from World War II, the famous castle and even a "pirate" island.
