The Biggest Music Festivals in Denmark in 2026, Ranked by Size

Denmark has a festival scene that is outsized for a country its size. Roskilde is one of Europe's biggest, Smukfest fills a forest for a week, and several others draw tens of thousands. Here they are ordered by estimated attendance for 2026, with notes on what makes each one different.

Attendance figures come from official festival press releases and verified sources. Where a festival uses daily capacity rather than unique visitors, or spreads across multiple cities, that is noted below.

1. GRØN Koncert: around 203,500 total across 8 cities

GRØN Koncert is a touring outdoor festival that visits eight Danish cities each summer. In 2026 it ran from 16 July in Tårnby through to 26 July in Valby, with stops in Kolding, Aarhus, Aalborg, Esbjerg, Odense and Næstved in between.

Total attendance across all eight stops reached around 203,500, according to the official GRØN Koncert site, making this the largest aggregate crowd of any Danish music event in 2026. Each individual stop draws roughly 25,000 festival goers. The 2026 edition sold out for the fourth consecutive year. A share of every locker booking on site, 25 DKK, goes directly to Muskelsvindfonden, the charity that owns and operates the festival.

The touring format sets GRØN apart from every other entry on this list. The 203,500 total is accurate, but it covers eight separate gatherings, not one.

2. Roskilde Festival: more than 130,000 attendees

Roskilde Festival is the largest single-site music festival in Northern Europe. The 2026 edition, its 54th, ran from 27 June to 4 July. Seven stages were in play: Arena, Eos, Fauna, Gloria, Lagune, Orange Scene and Platform.

Official capacity: more than 130,000 participants, supported by around 27,000 volunteers. About 50,000 tents went up in the camping areas. The site covers roughly 420,000 square metres. The festival is a nonprofit, with all surplus going to humanitarian and cultural causes. The 2026 lineup ran to 177 acts.

By the festival's own description, it becomes Denmark's fourth-largest city for eight days. Before going, see what you can bring into a Danish festival in 2026 for the rules on bags, liquids and permitted items.

3. Smukfest: around 60,000 attendees

Smukfest takes place in Skanderborg Dyrehave, a beech forest outside Skanderborg. The name translates loosely as "Denmark's most beautiful festival." The 2026 edition runs from 2 to 9 August, with camping available from 31 July.

The festival draws roughly 60,000 festival goers. Wikipedia cites this as the established capacity figure, and the festival itself describes it as Denmark's second-largest, behind only Roskilde. Stages sit among the trees, the terrain rises and falls, and a new electronic music stage, EKKO, launched in 2026.

Volt provides Event Lockers and charging throughout the week at Smukfest. Day and full-festival locker options are available. Booking in advance is worth doing for an eight-day run; see the Event Lockers page for how it works.

4. Jelling Musikfestival: around 40,000 attendees

Jelling Musikfestival brings roughly 40,000 festival goers to a small town in Jutland each May. The 2026 edition ran from 21 to 24 May. The festival runs on its "40,000 musikhjerter" (music hearts) framing, which appears on the official site as its stated audience target.

Jelling has run for decades and keeps a roots, folk and world music focus while widening its lineup year on year. The fact that it draws 40,000 people to Jelling, a town of a few thousand, says something about the pull.

5. Copenhell: around 39,000 per day over 4 days

Copenhell is Denmark's biggest rock and metal festival. The 2026 edition ran from 24 to 27 June on Refshaleøen, a former shipyard in Copenhagen about ten minutes by bike from the city centre.

Daily capacity hit a record 39,000 in 2026, with all ticket types selling out. Around 25 percent of 2026 visitors were attending for the first time, according to the official sold-out announcement. The 39,000 figure is per day, not a unique-visitor total: many festival goers bought multi-day passes, so the number of distinct people in attendance is lower than the daily-capacity-times-four arithmetic would suggest.

Volt provided Event Lockers and charging bundles at Copenhell 2026.

6. NorthSide Festival: 35,000 to 40,000 attendees

NorthSide is a three-day festival held at Eskelunden in Aarhus. The 2026 edition ran from 4 to 6 June with a lineup including Jack White, Idles and Skepta.

Attendance runs between 35,000 and 40,000 festival goers across the three days. All food served on site is 100 percent organic, which has become a defining part of the festival's identity alongside its emphasis on waste sorting.

7. Tønder Festival: around 25,000 attendees

Tønder Festival has run every August since 1975, making it one of Denmark's oldest. In 2026 it runs from 26 to 29 August in Tønder, southern Jutland. The programme covers folk, roots, country, blues and world music, with main-stage concerts running alongside spontaneous jam sessions in the streets.

Around 25,000 people attend each year. Friday and Saturday 2026 sold out ahead of the event. Check the official site for the current ticket position.

8. Musik i Lejet: boutique capacity, consistently sold out

Musik i Lejet takes place on the North Sealand coast in Tisvildeleje, running 16 to 18 July 2026 at a new site for this edition. Exact capacity figures are not published, but three-day passes sold out almost immediately and day tickets followed before the event.

The beach setting and limited scale put it in a different category from the festivals above. It belongs on a size-ranked list because the contrast is the point: The Danish festival scene runs from 130,000 at a single site to a few thousand on a beach, and both approaches sell out.

Volt is on site at Musik i Lejet.

How the numbers compare
