The event
Once every three or four years, GS Redan rigs rope courses on and inside the Basilica: three routes of increasing difficulty, more than 2,000 metres of rope and a spectacular view all the way to the Atomium. Around 250 participants from across Europe took part in the last edition. The event is open to experienced cavers; spectators are welcome to come and watch. Registration will open as soon as everything has been finalised.
