Basque Country Itinerary: The Best of Bilbao, San Sebastián & Beyond

The Basque Country packs extraordinary variety into a compact region: world-class museums, Gothic old towns, wild Atlantic coastline, and some of Europe's finest food. This guide covers the essential stops in and around Bilbao, from the Guggenheim to the fishing villages of the Bizkaia coast.

Hotels map

A well-planned Basque Country itinerary divides naturally into three layers: Bilbao's urban core, the surrounding coast and countryside of Bizkaia, and the road east to San Sebastián. Most travellers base themselves in Bilbao for at least two nights before extending outward. If you're still deciding how long to stay, the 2 days in Bilbao guide covers the city's essentials, while the Bilbao vs San Sebastián comparison helps you allocate time between the two cities. Bilbao also runs roughly 30–40% cheaper than San Sebastián for food and accommodation, so extending your base here makes budget sense. The metro, Euskotren, and regular buses mean you rarely need a car — though one opens up the best coastal roads.

Bilbao's Architectural Icons

Bilbao's physical transformation since the 1990s is one of the most studied urban regenerations in Europe. The Abandoibarra waterfront is ground zero for that story, but the architectural highlights extend well beyond a single neighbourhood. Give yourself at least a half-day to walk the riverfront from the Zubizuri Bridge to the Euskalduna hall without rushing.

1. Start Your Itinerary at Frank Gehry's Titanium Masterpiece

The Guggenheim is the anchor of any Basque itinerary. Budget 2–3 hours inside for the contemporary collection, but the exterior is equally unmissable. Book tickets online (around €18) to skip queues, especially in summer.

2. Meet Bilbao's Most Beloved Sculpture Outside the Guggenheim

Jeff Koons' 12-metre floral terrier outside the Guggenheim is free to see and impossible to miss. It's planted with tens of thousands of seasonal flowers, so it looks different depending on when you visit. A good five-minute stop.

The Casco Viejo & Bilbao's Cultural Core

The medieval old town sits on the right bank of the Nervión and remains the social heart of Bilbao. Its tight grid of streets, known as the Siete Calles (Seven Streets), is where you'll find the best pintxos bars, the covered market, and the city's Gothic cathedral. For a proper introduction to pintxos culture here, the Bilbao pintxos guide explains which streets to prioritise and when to go.

Bilbao's coastline stretches in both directions along the Bay of Biscay, and several of the Basque Country's most dramatic landscapes are within 45 minutes by car or metro. The Bilbao beaches guide covers which beaches suit which travellers, from families to surfers. For the wider coastal route toward San Sebastián, a car gives you flexibility to stop at Lekeitio and the Urdaibai reserve without being tied to bus schedules.

History & Culture Beyond the City

✨ Pro tip

For the coastal day-trip circuit (Gaztelugatxe, Bakio, Bermeo, Mundaka), a rental car is far more practical than public transport. The winding coastal roads between these stops are part of the experience, and the buses linking them are limited or require connections outside the summer high season.

FAQ

How many days do I need for a Basque Country itinerary covering Bilbao and San Sebastián?

A minimum of 5 days works well: 2 in Bilbao, 2 in San Sebastián, and 1 for a coastal or inland day trip. Seven days lets you add Guernica, the Urdaibai coast, and Gaztelugatxe without rushing. San Sebastián and Bilbao are about 100–120km apart, connected by frequent trains (around 2–2.5 hours) and buses (around 1 hour 15–30 minutes).

Do I need a car to explore the Basque Country?

Not for Bilbao and San Sebastián themselves — both cities have excellent public transport, and the train between them is fast and frequent. A car is worth considering for coastal day trips to places like Gaztelugatxe, Lekeitio, and the Urdaibai biosphere reserve, where bus connections are limited or slow.

What is the best time of year to visit Bilbao and the Basque Country?

May, June, and September offer the best combination of reasonable weather, manageable crowds, and lower accommodation prices. July and August are warmer but significantly more expensive, especially in San Sebastián. The Basque Country receives Atlantic rainfall year-round, so pack a waterproof layer regardless of season.

Is Bilbao or San Sebastián better as a base for a Basque Country trip?

Bilbao is generally 30–40% cheaper for accommodation and food, has better transport connections to inland destinations like Guernica and Gorbea, and offers more to do within the city itself. San Sebastián is closer to the French Basque Country and the eastern coast. Many travellers split their time between both rather than choosing one.

Can I visit Gaztelugatxe as a day trip from Bilbao?

Yes. Gaztelugatxe is about 35–40km northwest of Bilbao and reachable by car in around 45 minutes. There is a direct Bizkaibus service in the summer high season (check Bizkaibus schedules), and at other times you can reach it by changing buses in Bakio, but a car gives you flexibility to combine it with Bakio beach and the Bermeo fishing port in the same day. Arrive early or after 5pm to avoid the worst of the crowds.
