The estimate adds distance in km, climb in metres divided by 100, and extra for steep, high or demanding routes. Under 9 is easy, under 18 moderate, 18 or more hard. It is our own rule, not an official grade.
These are facts recorded in OpenStreetMap. We show no stars and no reviews.
Each layer names its source and date. Where we have no credible source it says not covered.
The national flood map shows no flood zone on or near this route. It covers only the river stretches the ministry has studied, so mountain streams are not included. Mapped zones do not predict flash floods in narrow valleys, so read the weather warnings before you go.

Wildfire danger changes every day, so it is shown as a live layer and not as a fixed value for the trail. Regional rules can close forest tracks or ban fires in summer. Ask the local authority if you are unsure.

At Bilbao Aeropuerto the average August afternoon high is 26.0 °C. This is an average from past decades, and heatwave days are much hotter. The lowest point of this route is 182 m, so start early and finish before midday from June to September.
Source: AEMET climate normals 1981 to 2010 for the nearest long record station. The route can be hotter or cooler than the station.
The highest point is 668 m. Snow is less likely here, but it can still fall and lie on paths in winter, especially on shaded sections. Check conditions before you go.
Snow months are a rule of thumb from the height of the route, not a snow report. Avalanche information is the official bulletin only, linked here.
OpenStreetMap shows 6 places where the route crosses a mapped river or stream with no mapped bridge. Small streams are often unmapped, so the real number can be higher. After rain a crossing can be too high to wade.

Most of this route carries no difficulty grade in OpenStreetMap, so we cannot say how exposed it is. Look at the map and the photos, and ask locally.
Points that volunteers have mapped in OpenStreetMap. Water, huts and toilets can be missing or out of date.
Timetables are not available here. Check them before you go.
These are rules of thumb from the length, climb and height of the route. They are not a complete kit list.
