The AP-8 is a tunnel-heavy transit route that saves time but costs you the soul of the Basque Country. If you have 6 hours to spare, the coastal roads offer a cinematic alternative. This isn't just a drive; it's a sequence of steep climbs, salty air, and narrow turns that require local knowledge to navigate smoothly.

Why Choose the Scenic Route Over the Highway?
Choosing between the AP-8 highway and the scenic coastal roads depends on your priority. The highway gets you there in 60 minutes but bypasses the very landscapes that make Northern Spain famous.
Taking the coast adds a few hours but rewards you with "Game of Thrones" filming locations and UNESCO biosphere reserves. This philosophy of "slow travel" is exactly what makes European road trips special.
1. San Juan de Gaztelugatxe: The Atlantic Fortress
Perched on a jagged island and connected to the mainland by a winding stone bridge, this hermitage is a masterpiece of coastal architecture. Known to many as "Dragonstone," its 241 steps offer a legendary payoff.
Time to spend: 90–120 minutes.
Parking Strategy: Don’t aim for the top lot (Urizarre); it’s usually full by 10 AM. Instead, use the larger Lurraldebus stop area or the overflow lot located near the Eneperi restaurant.
The Hidden View: Most people walk straight down the main path. For a better perspective, take the short trail behind the Eneperi restaurant. It offers a stunning profile shot of the bridge without the crowds.
2026 Permit Rule: You must secure a free permit via the official bizkaia.eus portal weeks in advance.

2. Urdaibai: The Green Marshes of Mundaka
Continuing east, the landscape opens into the Urdaibai estuary, a UNESCO-protected mosaic of marshes and oak forests. This area is the sanctuary for migratory birds and the "lungs" of the Basque coast.
Time to spend: 30 minutes (quick stop) or 1 hour (beach walk).
Parking Strategy: In the town of Mundaka, look for the lot near the cemetery (Mundakako hilerria). It’s a 5-minute walk to the famous surf lookout and usually has space when the port is packed.
The Driver’s View: Stop at the Mirador de Portuondo. There is a small gravel pull-off where you can see the turquoise sandbars shifting in the estuary.
Seasonality Note: In autumn, the mist over the marshes is incredible, but the GI-634 can be slippery. Drive with caution during the "sirimiri" (local light drizzle).

This transition from coast to inland reminds us of the Porto to Salamanca route, where scenery changes just as dramatically.
3. Zumaia: Tracking the Geological Tide
The Flysch of Zumaia is a breathtaking geological phenomenon where vertical layers of rock reveal over 60 million years of Earth's history. These "stone ribs" plunging into the Atlantic create one of the most alien landscapes in Europe.
Time to spend: 45–60 minutes.
Parking Strategy: Avoid the cramped town center. Use the industrial parking area on the street called Pantxita Etxezarreta kalea. It’s a 10-minute flat walk to the cliffs.
The Golden Rule: Tides Matter The famous formations are only visible at low tide. Check a local tide table before leaving Bilbao. If you arrive at high tide, the most dramatic rocks are submerged, leaving only a standard beach view.
The Best Angle Don't just stay on the sand at Itzurun beach. Climb up to the small chapel called Ermita de San Telmo. The path is narrow but safe, providing that classic "edge of the world" photo.

4. Getaria: Seafood and Txakoli Vineyards
Before the final stretch to San Sebastian, pull into Getaria. This walled fishing village sits at the foot of hills covered in Txakoli vineyards — the region’s signature slightly sparkling white wine.
Time to spend: 90 minutes (lunch + walk).
Parking Strategy: The port lot is expensive and often full. Try the parking lot at the entrance of the town, right next to the Cristobal Balenciaga Museum.
The Hidden Gem Walk past the outdoor grills to the very end of the pier. You can watch the local fishermen unloading the daily catch. This is the heart of the village's culinary fame.
The "Mouse" Hike If you have energy, the 20-minute hike to the top of Mount San Anton (locally known as the "Mouse of Getaria") offers a 360-degree view of the coastline you just traversed.

Frequently Asked Questions (FAQ)
Is the road from Bilbao to San Sebastian difficult to drive?
The coastal route is winding but excellently maintained. It is a comfortable drive for anyone used to standard European coastal roads.
Can I see all these stops in one day?

When is the best time for a Basque Country road trip?
May, June, and September offer the best weather. July and August are beautiful but require much earlier starts for parking.
