IMMER'SON 2026 - Intimate Music & Swimming Festival

Dive into a unique experience where music meets relaxation! IMMER'SON returns from September 4th to 6th, 2026 to transform Colo & Co (Castelnau-de-Montmiral) into a haven dedicated to music, swimming, and unforgettable encounters.

The lineup features 32 hours of music with a diverse program blending Dub, DnB, Techno, Trance, and Groove, all set in an exceptional natural setting just 45 minutes from Toulouse. With 23 local artists spinning the decks, each set promises to be an immersive sonic adventure.

Whether you're a sunbather or a beats enthusiast, enjoy the free-access pool, a bar on-site to quench your thirst, and a meal-inclusive pass to extend your experience in complete serenity. The intimate atmosphere and limited capacity of 200 ensure total immersion in a collective and warm energy.

A festival where music, nature, and conviviality come together for a weekend out of time. Don’t miss it!
