A well-built, real year-round indoor standing wave for the Belgium/Luxembourg border area, backed by real hotel infrastructure next door.
Surflux, branded Surf Luxembourg for its proximity to the Grand Duchy, is an indoor FlowSurf standing wave in Arlon, Belgium, next to a Van der Valk hotel just over the Luxembourg border. It opened in early 2026 as the first fully indoor FlowSurf venue in Europe, with the water heated to about 30°C year-round.
The FlowSurf system pumps a deep-water sheet up an inclined surface for a continuous standing wave ridden on real boards with fins, adjustable up to 1.8 meters. A mandatory beginner orientation applies to every first-time visitor regardless of prior surf experience.
Surfers in the Belgium/Luxembourg/France border region wanting a real standing wave without traveling to a coast, and anyone pairing a session with a stay at the adjacent hotel. The heated indoor water makes it a real year-round option regardless of season.
A standard 45-minute session runs about EUR 50 for intermediate/expert riders and EUR 55 for beginners (who need to be at least 1.3 meters tall), with board and a technical shirt included in both. Water stays heated year-round, so pricing doesn't vary by season.
Book online ahead, particularly on weekends. Pair a session with a stay at the adjacent Van der Valk hotel if you're traveling from further afield.
