I can be very direct on this topic: unless you really want to ride a Topple Tower (which isn’t even as impressing as it looks): don’g bother to spend a penny on Bellewaerde Park.
It used to be a beautiful park in the 90’s and early ‘00’s, but the past 10-15 years, maintenance declined terribly (much rides look terribly reglected), the Zoo part of the park is the absolute minimum and food & beverage is TERRIBLE throughout the entire park.
So as i said, unless you really want to ride a Topple Tower, don’t bother spending time and money on this park.
