The name 'Holle Bolle Boom' is derived from a well-known Dutch nursery rhyme character who is famous for an insatiable appetite.
The park's layout is specifically tiered to separate play zones for toddlers and older children to ensure safety.
The Plons water area utilizes specialized climate control to remain comfortable year-round, regardless of the outdoor weather in North Holland.
The site operates as a unified 'experience' park, meaning the three distinct zones are often bundled into a single admission visit.
De Holle Bolle Boom is a family-oriented leisure park located in Tuitjenhorn, specifically designed for children up to age 12. The facility is divided into three core themed areas: 'Binnen' (indoor playground), 'Buiten' (outdoor park), and 'Plons' (a heated indoor water park). The park is built around the legend of the titular 'Hollow Tree,' which features prominently in the site's decorative storytelling. The indoor playground offers diverse climbing structures, slides, and interactive zones suitable for various age groups. The Plons water park area features climate-controlled facilities and shallow play structures for younger children. The outdoor section includes traditional playground equipment and open green spaces. The entire venue is integrated into a single site at the Bongerdlaan location.
