When in Bilbao, you'll almost always pass by the striking Guggenheim Museum. The best view of the large building is from across the river. The Guggenheim Museum Bilbao is a modern art museum in Bilbao, in the Spanish Basque Country. It has an exhibition space of 11,000 square meters and features both a permanent collection and special exhibitions.

A beautiful vantage point. If the season is right, there's also the opportunity to watch whales. The path further to Gaztelugatxe, however, requires pushing because it's very overgrown. We didn't go far, but turned around and drove back along the road.

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