About Us
Carnaval of Screams (COS) is Yogyakarta's premier Halloween event promoter, delivering electrifying, immersive horror experiences. Since 2023, COS has set the standard for Halloween celebrations, attracting over 2,000 attendees per event.
With two successful editions in 2023 and 2024, COS continues to push boundaries with high-energy performances, eerie atmospheres, and cutting-edge production. Each year, we introduce new themes, attractions, and interactive elements to elevate the experience.
More than just costumes, COS blends top DJs, performers, and thrilling decor to create Yogyakarta's ultimate Halloween party.
2025 — THE CHARIOT. Nemeas and Manticore have arrived at the castle to meet The Chariot.
The time has come — destiny is in motion.
Under the veil of the Halloween Tarot, power, prophecy, and chaos collide in a night ruled by fate itself.
Step into the realm of cards and shadows,
where every scream turns the wheel,
and every soul draws their destiny beneath the crimson moon.
