No, tickets are not required and thus cannot be purchased on site, as entry to the market is free of charge.
The Hidden Purmerend Market operates on a free-entry basis, meaning there is no admission fee to access the market grounds. Consequently, no tickets are required for entry, and therefore, there is no ticket booth or facility to purchase tickets on site.
Visitors can simply walk into the market area and begin browsing the stalls. Any transactions for goods are conducted directly with individual vendors. This is typical for most local markets in the Netherlands and aligns with its community-focused nature.
