1. Re: what's the best way to travel from Barcelona to Madrid ? Without any doubt, the train is the best way to travel between Madrid and Barcelona. It makes the 620 km (385 miles) that exist between both cities in 2 hours and a half, at speeds up to 300 km/h (186 mph).
Please see the table below as it reads as straight line distance between the two city centers. e.g. Distance from Alicante to Madrid is 360 kilometers (straight line distance) which is approx. 430 km distance driving by car.
