Extrema Outdoor Belgium in Houthalen-Helchteren
Extrema Outdoor Belgium is a forest-and-lake techno festival at the De Plas recreational domain in Houthalen-Helchteren, run every May. Seven stages and a swimmable lake beach draw over 65,000 visitors across a weekend that many attend as a full campsite stay, from Thursday through Monday, rather than a single day trip.
Extrema Outdoor turns a forest-ringed lake at the De Plas recreational domain in Houthalen-Helchteren into a seven-stage techno campsite every May, complete with a swimmable beach worked into the festival footprint rather than fenced off from it.
