Barcelona to Castellón by road
The fastest driving route is 280 km (174 mi) long and takes about 3 hr 20 min without stops or traffic. It runs mostly on the AP-7 (204 km) and the C-32 (55.7 km).
It goes through 2 autonomous communities: Catalonia (193 km) and the Valencian Community (86.2 km). That’s an average of 84 km/h (52 mph). Spain’s traffic authority (DGT) recommends a break every two hours or 200 km: with 1 stop of 20 minutes, the trip takes about 3 hr 40 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 Castellón are 243 km (151 mi) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.
The road is 15% longer: for every 100 km in a straight line you drive 115. That’s a normal detour between two cities. Of the 120 Spanish driving pairs in this series, it ranks 104th for detour (the average is 24%).
From Barcelona, Castellón lies to the southwest (bearing 231°), and from Castellón, Barcelona lies to the northeast.
