Cañón del Río Lobos and San Leonardo de Yagüe Loop

The terrain is quite varied. You'll find tranquil paved roads, especially through the pine forests around San Leonardo de Yagüe, often with continuous ascents and descents. However, sections closer to or within the Cañón del Río Lobos Natural Park include unpaved dirt roads, some sandy areas, and narrow, stony paths. There are even river crossings with large stone blocks where you might need to dismount and carry your bike. A gravel or mountain bike would be more suitable for the full circular route through the canyon.

The full circular route, as described, is approximately 78.6 km long and is estimated to take around 3 hours and 30 minutes of active cycling time. Keep in mind that this duration doesn't account for stops to enjoy the scenery, visit landmarks, or navigate challenging unpaved sections.

While some paved sections are suitable for all skill levels, the full circular route is not recommended for beginner road cyclists due to significant unpaved sections, rocky paths within the canyon, and river crossings. These parts can be challenging and may require pushing or carrying your bike. If you're a beginner, consider adapting your route to stick to the quieter paved roads outside the canyon.
