Barcelona to Santander distance

Barcelona to Santander by road

The fastest driving route is 707 km (439 mi) long and takes about 7 hr 45 min without stops or traffic. It runs mostly on the AP-68 (291 km), the AP-2 (214 km), and the A-8 (72.5 km).

It goes through 6 autonomous communities: Catalonia (188 km), Aragon (182 km), Navarre (39.6 km), La Rioja (119 km), the Basque Country (102 km), and Cantabria (76.8 km). That’s an average of 91 km/h (57 mph). Spain’s traffic authority (DGT) recommends a break every two hours or 200 km: with 3 stops of 20 minutes, the trip takes about 8 hr 45 min. The time is OSRM’s estimate with OpenStreetMap data: no traffic and speeds somewhat below the limits, so real trips can differ.

Straight-line distance and bearing

In a straight line, the shortest distance over the Earth’s surface, Barcelona and Santander are 544 km (338 mi) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.

The road is 30% longer: for every 100 km in a straight line you drive 130. That’s a normal detour between two cities. Of the 120 Spanish driving pairs in this series, it ranks 30th for detour (the average is 24%).

From Barcelona, Santander lies to the northwest (bearing 297°), and from Santander, Barcelona lies to the southeast. The straight line reaches Santander on a bearing of 293°: on a sphere the bearing keeps changing along the way, which is why the shortest route looks slightly curved on a flat map.

Halfway between Barcelona and Santander

Halfway along the straight line, 272 km (169 mi) from each city, is the point 42.4615° N, 0.7667° W. It falls near Bailo (Huesca, pop. 265), 6.5 km away. The nearest town of 20,000 people or more is Huesca (pop. 55,454), 46.3 km away.

The nearest town of 20,000 people or more is Tudela (Navarre, pop. 38,903), 33.3 km away. The two midpoints are 83.8 km apart: if you want to meet halfway, the one on the road is the useful one.

By plane

A direct flight would take about 1 hr 10 min. That’s an estimate: 30 minutes for takeoff, climb, descent and landing, plus the 544 km straight line at 800 km/h (about 497 mph), a typical airliner cruising speed. Real schedules depend on wind, routing and airports, and not every pair has a direct flight.
