What Happened at Modem Festival 2026?
Modem Festival 2026 ran from 3 to 9 August 2026 at the usual site in Primišlje. The official social channels reported that the festival opened at The Swamp stage, and attendees have since posted reviews and recordings from the week. Organizers said in April 2026 that 70 percent of tickets were already sold.
The 2026 lineup was announced stage by stage. Aggregators listed Akuum, Acousma and AYIM as headliners. The official stage pages named a wide mix of acts. On The Hive, they included Giuseppe of Parvati Records, Digital Talk, Massern, Sivat and Tetraktyz. The Seed featured names such as Spekki Webu, Innersha and Hypnotic Black Magic. The Swamp featured Ayim, Zmayo, Yonagual and Nibiru, among others.
Where Is Modem Festival Held?
Modem Festival is held at Donje Primišlje 11, in inland Croatia, exactly halfway between the towns of Slunj and Ogulin. The official coordinates are 45.192991 N, 15.435222 E. The site is in a rural, wooded area, and visitors can enter through either the Slunj gate or the Ogulin gate, depending on their direction of arrival.
The nearest major airports are Zagreb and Zadar. Most international visitors combine a flight to one of them with the festival shuttles or a bus, as described below.
How Did Modem Festival Start?
Modem Festival started in 2012 as an expansion of the parties that director Tomislav Sijarto ran in Zagreb. In an interview on the official website, he said the goal was to bring darker, more experimental psychedelic music closer to the surface and to give it a full-scale production. Over the years, the festival grew from a single dancefloor into three stages that cover a range of tempos and styles.
The same interview describes some of the obstacles the team faced. A fire in 2018 destroyed the festival’s inventory, and in 2019 flooding raised the water level by about two meters overnight and swept away weeks of stage construction. He also said the festival was an early adopter of projection mapping and CNC-built stages, and that most of its money goes into art direction rather than headliners.
What Music and Art Does Modem Festival Offer?
The Seed
The Seed is the stage devoted to emerging artists and the newer currents of psychedelic music. The organizers describe it as a space for the sound of tomorrow, but it stays rooted in psychedelic music that moves both body and spirit.
The Swamp
The Swamp is the experimental stage. According to the director, it plays the same deep and dark style as the rest of the festival, but at slower tempos. The official description calls it a sonic lab where artists push boundaries and dissolve genre definitions.
The Hive
The Hive is described as a psychedelic playground, with a lineup of artists who shape sound across seven days. In the same interview, Sijarto said the team was planning a new Hive stage over a two-year period, to be presented at Modem 2027.
Art and Visuals
Art is a core part of the festival rather than decoration. The organizers run open calls each year for visual art and installations, and the official program page lists sections for music, arts and visuals, and a cultural area. The organizers say that despite being a smaller festival, their visual and decoration program competes with much larger events, and that this is one reason for the ticket price.

How Do You Get to Modem Festival?
Most visitors reach Modem Festival by using one of the two official shuttle services or by taking a bus to Slunj. Mo:Dem Express runs between Zagreb and the festival site. Permansio Shuttle connects several cities in Croatia and drops passengers directly at the camping entrance. Permansio passengers exchange their ticket for a wristband before departure, so they skip the gate queue, and the tourist tax is included in the fare.
Return tickets are sold separately for both services on the Mo:Dem Shop. Visitors can also take daily buses from major cities to Slunj using services such as Flixbus or GetByBus. Drivers can enter through the Slunj or Ogulin gate, and parking is available only to ticket holders. Inside the site, a festival shuttle runs between the gates and the camping entrances.

Where Do You Camp at Modem Festival?
Camping is included in every festival ticket, and it is allowed only in the designated, fenced camping area. You cannot camp next to your car because camping and parking are separate zones. Campervans, motorhomes, caravans and permanently converted vans need a Campervan Pass, which is limited to one per vehicle and goes on sale in September 2026. Ground tents are not allowed in the campervan area.
Visitors who prefer not to carry gear can rent tents and camping equipment from Utopia Camping, either online or at the on-site shop. Croatian law requires a tourist tax of €1.50 per day of stay, payable at the entrance, so bring exact change. Children aged 14 and under enter free with a ticket-holding parent or guardian, but the parent must register them in advance.
What Should First-Time Attendees Know?
Bring a valid ID or passport that matches the name on your ticket. All tickets are personalized, and name changes, transfers and resales are not possible. The festival does not accept copies of ID or written mandates, and it warns against buying tickets from individuals. Refund requests for 2027 tickets must be completed by 23:59 CEST on 15 May 2027 through your Mo:Dem:Space account. Refunded tickets go back on sale in June 2027.
Pack in layers, because August days can be hot and nights cooler. Sturdy closed shoes suit a large forested site, and a waterproof jacket is sensible given the weather events the director has described in the festival’s history. Save the official program page and your Mo:Dem:Space login before you travel, since they are the main places for schedule updates and ticket downloads.
