The Camping Albero D 'Oro is just leaving the motorway at Carrodano-Levanto on the A12 Genoa-Livorno and then follow the signs to Levanto and 5 Terre.
Immediately after the toll booth, turn left and take the direction Levanto SP 566 for about 15 minutes.
Arrived at the second roundabout turn left towards Monterosso on the SP43 and after about 100 meters on the right you will find the Camping Albero D 'Oro with its own parking lot (right image).
Below is a map of the area.
