The original Monkey Climber syndicate, the one you might have seen in Alan Blair's videos, etc. This one works with a proper waiting list. To put your name down for the waiting list now costs 25 euros, which will be deducted from your full ticket price of 250 euros once it's your turn to fish the lake situated in Westkerke, Oudenburg.
At the moment there's a good waiting list so no direct tickets available.
