Arzenál Vs Katlan: The Summer Festival 2026

Hi everyone! Many of you have been asking whether Katlan will return this year. Unfortunately, we still won’t be able to host events at the Tárnok Quarry, as the Dune series has been renewed for another season and filming will continue to occupy the location. We spent a long time thinking about what could replace it. Last year’s three day summer event at Arzenál turned out so well that the concept almost created itself. This year, we’re bringing the two worlds together once again: Katlan vs. Arzenál:The Summer Festival And it’s happening on one of our favorite dates, the August 20 long weekend, which has always delivered great parties in our experience. It’s also a period when some very exciting bookings become possible, and you’ll definitely notice that in the lineup. We’re extremely happy with how it turned out.
