The route integrates the former Plazaola railway, which historically connected Pamplona and San Sebastián.
EderBidea means 'Beautiful Path' in the Basque language.
The trail crosses the international border between Spain and France via the Bidasoa River bridges.
The route is part of the larger trans-European EuroVelo 1 network, which runs from Norway to Portugal.
Many of the tunnels along the route were originally engineered in the early 20th century for mining and passenger transport.
The path is part of a cross-border cooperation project co-financed by the European Union through the POCTEFA program.
EderBidea is a 90-kilometer cross-border cycle and pedestrian route connecting Navarre in Spain to the Pyrénées-Atlantiques region in France. The path follows the historic 'Plazaola' and 'Bidasoa' railway lines, repurposing former track beds into a greenway through the Bidasoa valley. The route serves as a segment of the EuroVelo 1 Atlantic Coast route, linking the coastal town of Hendaye to Pamplona. It features diverse topography, transitioning from lush, river-adjacent forests in the north to the rugged landscapes of the Navarrese interior. The trail crosses multiple tunnels and refurbished bridges that once facilitated steam engine transit. It is specifically designed for non-motorized travel, promoting slow tourism across the border regions. The Doneztebe section serves as a central hub for navigating the valley’s various secondary paths. Users can experience significant environmental shifts over the length of the route, reflecting the transition from oceanic to Mediterranean climates.

Carry front and rear lights for your bike, as many of the restored railway tunnels lack internal illumination.
Check local weather forecasts specifically for the Bidasoa valley, as heavy rain can occasionally lead to trail closures due to localized flooding.
Pack layered clothing, as temperatures can vary significantly between the shaded, river-side sections and exposed open fields.
Attempting the entire 90km route in a single day without prior endurance training or support, as it involves sustained elevation changes.
Cyclists must yield to pedestrians; keep to the right and use audible signals when overtaking.
