The castle is gigantic and beautiful to look at, unfortunately it has been surrounded by a construction fence for ages. Unfortunately, you can't see much. Whether the detour is worth it, everyone has to decide for themselves.

Definitely a highlight, but unfortunately, the castle was covered in scaffolding when I visited. The castle dates back to the Middle Ages but was later almost completely rebuilt.

The Arbina dam backs up the river bed of the Butrón River. Here the environment is full of oak groves, lime trees and, in some areas, alder, ash and acacia trees.

Komoot currently features a selection of gravel bike routes around Gorliz that prioritize low-traffic areas. While the region offers a broader network of trails suitable for gravel biking, our curated collection focuses on routes designed for a more serene experience. For example, you can explore the challenging Butrón Castle – Playa de Gorliz loop from Plentzia, which offers extensive stretches away from main roads.
The no-traffic gravel trails around Gorliz offer a diverse mix of terrain. You'll encounter coastal paths with stunning sea views, green fields, and extensive pine woods. Some routes venture into inland hills, providing more challenging ascents and descents. The region's unique blend of landscapes ensures a varied and engaging ride, from the Bay of Biscay coastline to the Butron Estuary.
While many of the listed gravel routes in Gorliz are rated as difficult due to their length and elevation, the region's extensive network of paths and forest tracks often provides opportunities for adapting shorter, less strenuous sections. For a more relaxed experience, consider exploring parts of the pine woods or paths along the Butron Estuary, which can be more suitable for families looking for quieter rides. Always check the route details for elevation and surface before heading out.
Many gravel routes in the Gorliz area pass by or offer views of significant landmarks. You can encounter the impressive Butrón Castle, a medieval fortress that adds a historical touch to your ride. The dramatic cliffs along the Cantabrian Sea often lead to panoramic viewpoints, such as those near the Gorliz Lighthouse. Other points of interest include the unique Petrified Dunes of Astondo and various historical sites like the Ruins of Askorriaga Fortress.
Yes, Gorliz is well-suited for circular gravel routes. Many of the trails are designed as loops, allowing you to start and end your ride in the same location without retracing your steps. For instance, the View of the Jata Coast – View of Bakio loop from Mungia is a substantial circular route that takes you through varied landscapes and offers stunning coastal vistas.
Gorliz benefits from a mild microclimate and receives a good amount of sunlight, making it suitable for gravel biking year-round. However, spring (April-June) and autumn (September-October) generally offer the most pleasant conditions with moderate temperatures and lush scenery. Summers can be warm, especially inland, while winters are mild but may bring more rain. Always check the local weather forecast before your ride.

Yes, public transport can be a viable option for accessing some gravel bike trails, especially those starting in towns like Plentzia. Plentzia is connected by metro (Line 1) to Bilbao, and many routes, such as the Butrón Castle – Playa de Gorliz loop, can be started from there. Always check the public transport operator's rules regarding bicycles, especially during peak hours.
Generally, dogs are welcome on many outdoor trails in the Gorliz region, especially on less crowded gravel paths and forest tracks. However, it's crucial to keep your dog under control, preferably on a leash, to ensure the safety of other trail users, local wildlife, and livestock. Always clean up after your pet. Specific rules may apply in certain protected natural areas or private lands, so look for signage.

For example, routes starting or passing through Plentzia, Mungia, or Bakio offer opportunities for a coffee break or a meal. It's always a good idea to carry sufficient water and snacks, especially on longer, more remote sections.
