Freediving in Denmark
Including Bornholm Island Coast, Furesø Lake, and Lillebælt Strait. On the map.
The vibe
Freediving here is a quiet, introspective practice that requires a high tolerance for cold and a deep appreciation for the stark beauty of northern marine environments. You will find the most comfort in the brief window of late summer, though the dedicated community stays active whenever the conditions allow for clear visibility. It feels like a private, club-oriented scene where you are more likely to meet passionate locals training in the shallows than any other travelers.
Bornholm Island Coast

The rocky granite coastline of Bornholm offers some of the clearest water in the Baltic Sea, with dramatic underwater cliffs and boulder-strewn seabeds. Freedivers frequent these areas for the rugged topography and the feeling of open-ocean diving within the Baltic.
Access. Local freediving groups on the island facilitate shore-entry dives and boat-based trips to the deeper granite walls surrounding the island.
Notes. Exposed to open sea conditions; weather monitoring is critical for safety.
Furesø Lake
Capital Region of Denmark

As Denmark's deepest lake, Furesø offers a unique freshwater freediving environment with depths reaching over 37 meters. The calm, protected water provides a stable platform for constant weight training and breath-hold technique refinement away from coastal currents.
Access. Located near Copenhagen, the lake is accessible via local freediving clubs that organize regular training sessions and line-diving meetups.
Notes. Water temperature varies significantly with depth; thermal protection is required year-round.
Lillebælt Strait

Lillebælt is renowned for its diverse marine life, including frequent harbor porpoise sightings, making it a premier spot for wildlife-focused freediving. The unique topography of the strait creates varied depths and sheltered bays suitable for both training and observation.
Access. Freediving schools based in Middelfart and Fredericia provide specialized courses and wildlife-spotting charters that prioritize non-intrusive breath-hold encounters.
Notes. Currents can be exceptionally strong due to the narrow passage; timing dives with slack water is essential.
Øresund Strait

This strait between Denmark and Sweden features interesting wreck sites and rocky outcrops that are popular for recreational freediving. The area is known for its clear visibility during specific tidal windows and provides a unique opportunity to explore maritime history on a single breath.
Access. Several dedicated freediving centers in the Copenhagen and Helsingør area offer guided boat trips to the best wreck sites and shallow reef zones.
Notes. Strong currents are common; boat traffic is heavy, so surface markers are mandatory.
