GR 109 Interior Asturias

The GR 109 Interior Asturias is commonly divided into 27 stages across the interior of Asturias. The route starts at Panes and finishes at Santalla, with individual stages ranging from short days such as Espinaredo to El Fresnedal at 8.85 km to longer days such as Bisuyu to Berducedo at 27.5 km.

The GR 109 Interior Asturias is 482.77 km long with 16,296 m of total ascent, which places it firmly in the extra difficult category. It is a true multi-day crossing of inland Asturias, so it is better suited to experienced long-distance hikers than to casual day walkers.

The GR 109 Interior Asturias begins in Panes in eastern Asturias and ends at Santalla in the Oscos area in western Asturias. Along the way it passes through a long chain of inland towns and villages including Alles, Carreña, Benia, Cangas de Onís, Campumanes, Bárzana, Tuña, Berducedo, and Grandas de Salime.

Most hikers planning the GR 109 Interior Asturias use the standard 27-stage breakdown, so a full end-to-end hike typically takes about 27 days if walked one stage per day. Strong hikers may combine shorter stages, but the overall distance of 482.77 km and 16,296 m of climbing still makes it a major long-distance commitment.

The GR 109 Interior Asturias crosses a broad swath of inland Asturias through places such as Panes, Alles, Carreña, Benia, Cangas de Onís, Villamayor, Espinaredo, Campumanes, Bárzana, Belmonte, Tuña, Ounón, Berducedo, Grandas de Salime, Castro, and Santalla. That east-to-west line is one of the route’s defining features and helps explain its reputation as a full traverse of Asturias interior.

Yes. The GR 109 Interior Asturias is well suited to section hiking because it is already organized into 27 stages with clear settlement-to-settlement breaks such as Panes to Alles, Benia to Cangas de Onís, and Grandas de Salime to Castro. That makes it practical to tackle the route in several trips rather than as one continuous 482.77 km journey.
