The Basque Country is a fascinating mix of culture, history, nature and gastronomy. This route from Biarritz, in the northwest, to Isaba, in the southeast, covers a large part of the Basque Country. This route can be a challenge for the less experienced motorcyclist in bad weather. Poor visibility due to low clouds, stray cattle in the mountains, in combination with narrow mountain roads require concentration and driving skills. The route is completely paved.

The fashionable Biarritz in France, also seen as a surfers' paradise, is the starting point of the route. The route goes along the coast towards Saint-Jean-de-Luz. This picturesque coastal town has everything you expect from a French coastal town. 15km further on you cross the border for the first time today. Hondarribia, is the first Basque town on this side of the border. It is a charming town with colorful houses, narrow streets and a medieval castle. Just outside the city is the Jaizkibel, in cycling the Jaizkibel is included every year in the Clásica San Sebastián. So you can meet many cyclists here. You must pass this at a minimum distance of 1.5 meters. At the highest point there is a beautiful viewpoint with a view of the coast and the ocean. After the descent back to Hondarribia it is time for coffee. Panaderia Ondare is a beloved bakery of the locals. Highly recommended.
Continuing the route you follow the Bidasoa river for a while before leaving the main road and heading into the mountains. 15 kilometers further you have already conquered the first mountain of the day. You are now back in France. Here the roads are narrow, mind your speed. Another 15 kilometers further you drive back into Spain. The roads are narrow again and the quality is not always the best. Watch out for stray cattle!
Descending gently you arrive back in a more inhabited area. That's a good thing because it's time for lunch. In Elizondo, Restaurant–Bar Juli is a hidden gem. A small restaurant with an enthusiastic owner and delicious dishes.
After lunch the route climbs again. The border is again at the next mountain pass. This is a viewpoint with a view over the valley that runs deep into France. The way down will also have several points where you may want to stop for a photo. When the route bends south again, the road goes up again. The last border crossing of today is coming up. Here you will find the megalithic (sanctuary or funerary monument) complex of Cromlech de Organbide. One of many in the area. The road slowly brings you back to civilization. For a while then, because after Aribe, where there is still a small supermarket and a gas station, towns become smaller again and the roads are quieter again. The route continues for another 50 kilometers through wooded areas before you reach the end of the route.

Isaba is at the end of the route. This picturesque little village is the stopping place for active sports enthusiasts in both winter and summer. The hotels and restaurants in the village are small-scale and clearly not aimed at mass tourism.
