Great view of the peninsula! In my opinion, you can save yourself the trip to the peninsula and the online registration process.

A low point on the tour. It was a Sunday and all the restaurants were packed. When I politely expressed my wish to be able to charge the battery in Spanish, we were literally thrown out. Spaniards drive long distances to eat out on Sundays. It has never happened to us that the battery was not allowed to be charged. Of course we would have eaten and drank. The whole place was almost entirely made up of holiday apartments, with the blinds down and totally dead without the lunch guests. No hotel, no guesthouse, but with a train station. Cheers to the Euskotren regional train in the Basque Country, on time, super helpful staff. So take the train back to Gernica!!!

Completely destroyed by the German Condor Legion in the Spanish Civil War. https://de.wikipedia.org/wiki/Luftkampf_auf_Guernica A well-worth seeing exhibition in the central square shows the horrors of the civil war. The Spanish spelling with "ue" probably goes back to Picasso.

You'll encounter coastal paths with stunning views, routes along the estuary with its extensive marshes, and inland hills like Mount Katillotxu. The trails often combine paved and unpaved segments, including sandy areas, dense forests, and coastal cliffs, providing varied landscapes for exploration.
While many of the featured routes around Mundaka are considered challenging, the region's diverse terrain within the Urdaibai Biosphere Reserve does offer options for varying ability levels. For a less strenuous experience, focus on paths closer to the estuary or explore the flatter sections of the coastal routes. Always check the route details on komoot for specific difficulty ratings and elevation profiles.

For example, the Fantastic view from the top – Viewpoint Bakio Bay loop from Bakio is about 9.6 miles (15.5 km) and takes approximately 1 hour 41 minutes. Longer routes, such as the Guernica Mural in Gernika – Artzubi Bridge loop from Gernika, which is 18.9 miles (30.4 km), can take around 3 hours 9 minutes. Always consider your fitness level and planned stops when estimating your ride time.
Mundaka's gravel routes often pass through the stunning Urdaibai Biosphere Reserve, offering views of the estuary, extensive marshes, and the Cantabrian Sea. You can also discover notable landmarks such as the Santa Catalina Hermitage and Mundaka Harbor, which provides spectacular views. Other points of interest include the Guernica Mural in Gernika, or the unique Oma Forest.

The Mirador de la Atalaya and Portuondo viewpoint also offer impressive views of the estuary and the famous surf waves. Many routes, like the Fantastic view from the top – Viewpoint Bakio Bay loop from Bakio, are specifically highlighted for their scenic outlooks.
Mundaka, being a popular destination, offers various parking options. You can typically find public parking areas within the town or near popular trailheads. It's advisable to check local signage for any restrictions or fees, especially during peak season. For routes starting outside Mundaka, like those from Bakio or Gernika, parking facilities are usually available in those towns.
Public transport options to Mundaka and surrounding areas in the Basque Country often accommodate bicycles, though policies can vary. Euskotren, the local train service, generally allows bikes outside of peak hours. Buses might have limited space or specific regulations for bikes. It's recommended to check the specific public transport provider's website for their current bicycle policy before planning your trip.
As Mundaka is located within the UNESCO-declared Urdaibai Biosphere Reserve, cyclists should be mindful of environmental regulations. Stick to marked trails, avoid disturbing wildlife, and practice Leave No Trace principles. While general cycling is permitted on designated paths, specific areas might have restrictions to protect sensitive ecosystems. Always respect local signage and guidelines.
Mundaka benefits from a mild year-round climate with infrequent frost, making it suitable for gravel biking for much of the year. Spring and autumn generally offer the most pleasant conditions with moderate temperatures and less rainfall. Summer can be warm but is also popular, especially along coastal routes. Winter rides are possible, but be prepared for cooler temperatures and potentially wetter weather.
Yes, many of the gravel bike routes in the Mundaka area are designed as loops, allowing you to start and end in the same location. For instance, the Bermeo Harbor – Bermeo Harbour loop from Bermeo offers a circular exploration of the coastal scenery. These loops are convenient for day trips, as you don't need to arrange return transport from a different endpoint.
While the featured routes in this guide are generally rated as difficult, the Urdaibai Biosphere Reserve offers a variety of paths. Families with younger children or those seeking a more relaxed ride might find flatter sections along the estuary or less challenging coastal paths more suitable. Always check the route's elevation profile and distance on komoot to ensure it matches your family's ability level.
Bringing dogs on gravel bike routes in Mundaka is generally possible, especially on public paths. However, as the area is part of the Urdaibai Biosphere Reserve, it's crucial to keep dogs under control, preferably on a leash, to protect local wildlife and respect other trail users. Always clean up after your pet. Some specific areas or nature reserves within the Biosphere might have stricter rules, so look for local signage.
