The Castle of Butrón is currently closed to visitors, but the castle grounds are open to the public. The gardens make a fine place for a picnic, and several pleasant trails explore the wooded areas around the property. Visit on your own from Bilbao or as part of a full-day tour of Basque towns, and see other top sights like the Vizcaya Hanging Bridge, the Urdaibai Biosphere Reserve, and the Old Port of Algorta.
The Castle of Butrón is located in Spain’s Basque Country, 11 miles (18 kilometers) north of Bilbao. The easiest way to get there is by car or as part of a guided tour. It's possible to go by bus from Bilbao, but requires multiple transfers. The area is also a popular place to explore on bike.
The castle interior is not currently open to the public, but visitors can enjoy the castle exterior and grounds any time of year. July and August are the busiest times to visit Basque Country, so if you travel outside the summer season, you'll avoid crowds and save money on accommodations.
Bilbao is the largest city in Basque country, well-known for its architecture, vibrant food scene, and surrounding mountainous landscapes. The Frank Gehry–designed Guggenheim Museum is the city’s most popular sight, and the nearby San Juan de Gaztelugatxe hermitage served as the filming location for Dragonstone in the series Game of Thrones.
