Yes, you can use public transport to get to the event venue.
This year the Luminosity Beach Festival 2022 will take place at Bernie’s Beach Club in Zandvoort (Boulevard Barnaart 65, 2041 JA, Zandvoort, The Netherlands). We would recommend visitors of the festival to come with public transport if possible.
If you come by car, please keep in mind that especially during sunny days the beach is a very busy place for tourists! This means the boulevard only has a limited amount of parking spots available.
