Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.
Copenhagen Airport (CPH) is the main international hub for the Danish Sound and connections onward to Bornholm; Helsingor is reached via the Coastal Railway. Billund Airport (BLL) is practical for Little Belt, with onward car or bus/rail transfer toward Middelfart. Bornholm Airport (RNN) near Ronne receives regular DAT flights from Copenhagen; other domestic services may be seasonal. Alternatively use Bornholmslinjen ferries from Ystad in Sweden or Koge on Zealand. Check international passport/transit conditions even if traveling to a Danish island via Sweden. Denmark proper is interconnected by bridges, rail and regional ferries, but not every dive beach is transit-friendly with tanks.
Copenhagen Airport
CPH • EKCH
Approx. 60 km by road to Helsingor • About 1 to 1.5 hours to Helsingor by rail with connections; check current route
Principal international airport for Copenhagen and the Oresund and North Zealand coast; also connects to Bornholm flights.
Transport: Airport rail, Coastal Railway via Copenhagen, Rental car, Pre-booked transfer
Billund Airport
BLL • EKBI
Approx. 59 km road distance to Middelfart • Approx. 45 to 60 minutes by car; public transit requires connections
International gateway for the Jutland and Funen shore of Little Belt, including Middelfart and Fredericia.
Transport: Rental car, Bus to Vejle and onward train, Pre-arranged transfer
Bornholm Airport
RNN • EKRN
5 km to Ronne • Short local taxi or BAT bus trip, timing varies by service
Island airport near Ronne for Bornholm; principally domestic air connections from Copenhagen.
Transport: Taxi, BAT local bus, Car rental
For North Zealand, use DSB and the Coastal Railway between Copenhagen, Humlebaek and Helsingor; the harbor, castle and aquarium are walkable from Helsingor station. For Little Belt, intercity rail serves Middelfart and Fredericia, but a car or taxi simplifies moving tanks between shore entries. For Bornholm, use a car, bike and BAT buses depending on the base; some rock beaches are not convenient with heavy scuba gear. Rejseplanen is the main multimodal journey-planning tool. Ferry schedules, bridge traffic and weather can affect island connections.
Denmark is in the Schengen Area. For most non-EU short-stay visitors, the standard allowance is up to 90 days in any rolling 180-day period across Schengen, subject to nationality and immigration status. Non-EU passports generally must be issued within the previous 10 years and remain valid at least three months beyond intended departure. EU/EEA nationals generally travel using accepted passports or national identity cards. Denmark's external-border Entry/Exit System (EES) applies to relevant non-EU short stays. As of November 8, 2026, the official EU ETIAS site says ETIAS is not yet operational and is not accepting applications; recheck before departure rather than paying intermediaries. Separate Faroe Islands and Greenland rules are not covered here. Visa, health and entry decisions remain authority-specific.
Bring proof of certification, a logbook or recent experience record where requested, and pre-book any guide, charter or rental. Bornholm dive centers list air/nitrox and equipment services by arrangement; Hindsgavl Camping near Middelfart documents cylinder filling by prior agreement. Confirm gas type, valve compatibility, exposure suits, drysuit training, weights, pickup hours and whether a named boat excursion actually departs. Ask the operator about an Alpha flag, SMB, rescue oxygen and medical evacuation plan. A 5mm suit may not be warm enough in colder months; choose thermal protection by local advice, not a national rule.
Danish krone (DKK)
Cards and contactless payment are widely used in cities, coastal towns, museums and operators. Prices are normally in DKK, not EUR. Confirm an operator accepts your international card and whether a seasonal campsite or very small vendor requires another method.
Bank ATMs are common in Copenhagen, Helsingor, Fredericia, Middelfart and Ronne; expect fewer convenient machines in small Bornholm coves and remote villages. Machine fees may be displayed before withdrawal.
230V • 50Hz • C, E, F, K
Type K is distinctive to Denmark; many hotels also accept common two-pin European plugs. Use a grounded adapter when required and verify chargers are dual-voltage. Boat sockets and cylinder charging arrangements differ by operator; ask before bringing powered dive equipment.
Communications
Mobile signal, card payments and Wi-Fi are reliable in main towns, but rocky coastal coves, offshore boats and remote island corners may have weak reception. EU/EEA roaming may apply to eligible plans; travelers from elsewhere should review fees and consider an eSIM. Download maps and the DMI forecast before heading to a remote beach, and keep a working emergency phone protected from water.
Language
Danish is the official language, and English is widely spoken in tourism, airports and dive businesses. Place names and signs can retain Danish spellings; confirm the exact harbor or beach meeting point instead of relying on approximate anglicized place names. German and Scandinavian languages may also be useful near borders and visitor areas.
Insurance
Check travel medical, scuba and evacuation cover for Denmark, including cold-water diving, depth, wreck dives, drysuit use and any technical or overhead activity you plan. An EU health card does not replace travel insurance or necessarily cover evacuation, specialist diving expenses or trip cancellations. Confirm operator insurance, liability, emergency oxygen and recompression arrangements before booking a dive boat.
Packing list
Plan for a cool, windy maritime climate: base layers, rainproof shell, grippy shoes and a warm dry change. For diving bring suitable thermal protection (often hood, gloves, boots and a properly fitted wetsuit or drysuit), plus computer, mask, SMB and locally compliant Alpha-flag plan. For snorkeling carry a fitted mask, sufficient warmth and bright surface identification. Pack medication, insurance details, certification evidence, a power adapter and transport tickets.
