Discovery Combi (B-Excursion) is a very advantageous combination ticket allowing you to make a return trip (in 2nd class) from any Belgian railway station. The railway station at De Panne is within walking distance from the park’s entrance (accessible through a special footpath).
Besides the sale of individual Discovery Combis (B-Excursions) you can also buy single presale tickets (only access, no train journey) at all Belgian railway stations of the NMBS. Discovery Combis (B-Excursions) for groups and school groups should always be booked in time with the Group Travel department of NMBS.
