The Bidasoa reaches the Cantabrian Sea at Txingudi bay next to Cape Higuer between Hendaye and Hondarribia, forming the Chingudi wetlands that include Jaizubia floodplains, Plaiundi. The Bidasoa islands and Fiasan (Pheasant) Island. After Urdaibai in Bizkaia, this area is the second largest maritime wetland in the Basque Country. In 1988 Plaiaundi Environmental Park was created within the wetlands, an excellent example of how to restore a dried up degraded wetland to its original state.

Those taking the Way of St. James here on the coast save many meters of elevation gain when crossing the Pyrenees. However, many pilgrims take the other route over the mountains: on foot from St. Jean-Pied-de-Port over a pass to Roncesvalles in Spain.

With an MTB if you continue further, there is a very easy track to cycle on which you have spectacular views of the coast.
