On Saturday, July 4, 2026, the open-air theater at the Helderse Vallei transforms into an atmospheric festival site during Trapop. What once began as a spontaneous initiative by the band STAGE2 during the pandemic has since grown into a beloved annual music festival. The location, surrounded by greenery, creates an intimate and summery atmosphere.
With a packed program full of live performances, delicious food, drinks, and (hopefully) glorious sunshine, Trapop guarantees a wonderful day out for music lovers of all ages. Don’t forget your festival chair and come enjoy music outdoors!
