What to expect

You'll start with a short drive into the Basque hills, then collect your bike and begin following the old railway bed. The trail is gently rolling, rarely steep, and winds beside a river through thick forest. Expect to pass through several tunnels carved during the mining era—bring a light or use your bike's headlamp. Small hamlets appear unexpectedly. You'll pause at scenic spots where many riders take photos or rest. Around midway through, you'll stop for a Basque picnic with cured meats, potato omelette, and local cheese. The route finishes at the river where you can wade in to cool down before heading back to the city by van.
