When leaving Malaga Airport follow the signs for Algeciras/ Cadiz - Marbella isn't marked

When you get onto the Autovia (Motorway) stay in the same lane for about 2/3 minutes and you will reach Km 229 - Here you bear to the right and get onto the A7 - Don't take the N340

If you follow this until you near Fuengirola - keep to the left hand lanes and follow the A7 - You'll see Peaje (Which is Spanish for Toll) - It costs 3/4 euros but it takes you straight to Marbella in about 30 mins without any complications.
