Bilbao Volcano Gravel Day — 88 km Hard Full Day

This is a hard full day. It suits riders who are already comfortable covering 80 km or more and who can handle roughly 1,600 m of climbing without needing to stop often. Good gravel bike handling helps, because tracks through the volcanic hills and woods will not always be smooth.

If you are new to gravel, the Bilbao riverside gravel intro is a better start. If you want a shorter hard effort, look at the Bilbao big climb morning instead.

The route links gravel tracks between extinct volcanoes with a long stretch through beech forest. Expect a mix of climbing and descending rather than long flat sections: 1,600 m over 88 km averages out to a steady rise throughout the day.

The volcanic ground and the woodland tracks change character as you go. Open sections give wide views over the crater landscape, while the beech forest is more enclosed and cooler. Exact track conditions depend on recent weather, so ask the partner when booking.

The Bilbao forest gravel loop is 72 km of forest and farm lanes and is the mid-level choice. The Volcano Gravel Day adds 16 km and noticeably more climbing, and its scenery is volcanic rather than pastoral.

The Bilbao riverside gravel intro is 34 km on wide, forgiving tracks. Think of this ride as the step up once you are fit, confident on loose surfaces and ready for a long day.

Plan for a full day out. Bring enough food and water for several hours between stops, spare layers for the shaded forest and a repair kit if the partner does not supply one. Tyres suited to mixed gravel make the descents more comfortable.

Try a ride of 70 km or more with some sustained climbing in the weeks before. Check with the partner when booking about bike hire, lunch arrangements and what to bring.
