Following the Bidasoa River along the Tren Txikito (Little Train)

The Bidasoa is a small Basque–Navarrese river that, for most people, immediately evokes the border crossing at Irún into France. Its borderland character, together with the railway that once ran beside it, gives this route its distinctive identity.

NOTICE (04/12/2025): Due to a landslide, the Bidasoa Greenway is closed from the Montoia Tunnel to Zalain Zoko. 

NOTICE (27/11/2025). Closure of the greenway between Berrizaun and the Blue Bridge in Sunbilla due to works to improve safety on the route. The closure is expected to last from 28 November to 31 December 2025.

NOTICE (26/08/2025). The section of the Bidasoa Greenway between Doneztebe-Santesteban and Sunbilla will remain closed until the end of the year due to safety and improvement works on the route.
