Bornholm DenmarkCruise Port Guide

Bornholm is Denmark's easternmost island, a granite anomaly in the middle of the Baltic Sea — geologically more akin to the Scandinavian bedrock of Sweden than to the soft chalk and clay of the Danish mainland — lying equidistant between Denmark, Sweden, Germany, and Poland. It is often called the 'Sunshine Island' (Solens Ø) in Danish tourism for its disproportionately warm, sunny summers relative to the rest of Scandinavia, and it has attracted artists, craftspeople, and holidaymakers since the late 19th century with its combination of rugged granite coastline, amber beaches, medieval round churches, dense forests, and the extraordinary culinary tradition centered on its centuries-old smoking houses.

Rønne, Bornholm's largest town and the cruise port, is a charming, small Danish port city of pastel-painted half-timbered houses, cobblestoned streets, and the Gamle Stan (Old Town) district of Laksegade and Storegade, which survived 20th-century development largely intact. The cruise pier, expanded in 2025, is within easy walking distance of the town center. The island's physical climax is Hammershus — Northern Europe's largest medieval castle ruin — occupying a dramatic headland of sheer granite cliff at the island's northwestern tip, its massive round towers and curtain walls rising from a rock outcrop that has made it militarily impregnable since construction began in 1255. The ruins are freely accessible and extremely well preserved, with extensive walking paths through the fortifications and spectacular Baltic views.

The fishing village of Gudhjem on the northeastern coast is Bornholm's most picturesque settlement, its steep streets tumbling down to a small harbor dominated by working smokehouses. The local specialty Sol over Gudhjem (Sun over Gudhjem) — a smoked herring fillet placed on a piece of dark rye bread (rugbrød), garnished with raw egg yolk, radishes, and chives — is one of Denmark's most iconic regional dishes and should be eaten here, in situ, with a cold Bornholmer beer. The island's four distinctive round churches (Rø, Olsker, Nylars, Østerlars) — medieval defensive towers of uncertain purpose, their conical lime-washed forms unique in Scandinavia — are among the most architecturally singular monuments in Denmark. Dueodde, on the southern tip, has a vast beach of ultra-fine white sand regarded as some of the finest in northern Europe.

Getting Around from the Port

The 2025 expanded cruise pier at Rønne is approximately one kilometer from the town center, an easy and pleasant walk. For exploring the wider island, bicycle rental from agencies near the harbor (approximately 100–150 DKK per day) is the classic and highly recommended option; Bornholm is famous for its cycling infrastructure, with well-marked routes connecting all major sites. The island's bus system (BAT) runs regular services from Rønne to Hammershus, Gudhjem, Allinge, and other towns; Bus 7 operates an anticlockwise island circuit from May to September. Taxis are available but limited; arrange returns in advance for remote locations. The distance from Rønne to Hammershus by road is approximately 30 km (40 minutes by car or bus). Organized shore excursions to Hammershus and Gudhjem typically cost €40–60 per person.

Attractions and Activities

Hammershus (free entry, open at all times) is the unmissable site: the ruins of Northern Europe's largest medieval fortification, spread across a magnificent granite headland, with views over the Baltic and the Hammerhavn fishing harbor below. Allow two hours minimum. The adjacent Opalsø (Opal Lake) is a striking turquoise quarry pool at the foot of the cliff. Gudhjem village rewards a two-hour visit: the smokehouses (Røgeriet Gudhjem, among others) are working establishments where herring, mackerel, and salmon are smoked over alder wood in open brick kilns, and can be toured — or simply sniffed and consumed. The Østerlars Round Church (5 km south of Gudhjem), the largest on the island, is worth combining with the Gudhjem excursion. The Bornholm Art Museum (Bornholms Kunstmuseum) near Gudhjem, designed by Henning Larsen in a spectacular cliff-edge setting, houses a superb collection of Bornholm-associated artists from the late 19th century to the present. Dueodde beach makes a relaxing alternative for passengers prioritizing a long sandy swim.

Dining & Shopping

Rønne has several good cafés and restaurants. Bornholm's signature food culture centers on smoked fish (sild/herring is the classic, though mackerel and salmon are also excellent), served on rugbrød with butter and traditional garnishes. The Sol over Gudhjem open sandwich is the island's most celebrated dish. Eel smoked over alder is a Bornholm specialty seldom found elsewhere. Local cheeses, honey, and cherry products from the island's orchards are also distinctive. The island's amber tradition — Baltic amber washed up on Bornholm's beaches — makes distinctive local jewelry. Bornholm is known for its studio ceramics and glass; several high-quality ceramic artists have studios on the island, particularly around Gudhjem and Allinge.

Weather

The cruise season on Bornholm, Denmark's 'Sunshine Island,' runs from May to September with pleasant Baltic summer temperatures between 60–72°F (15–22°C). Bornholm receives more sunshine than the rest of Denmark, but Baltic breezes and occasional showers still occur, so light layers and a packable rain jacket are always useful. The remarkable round churches, smoked herring culture, dramatic granite cliffs, and sandy beaches make Bornholm one of the Baltic's most unique and rewarding island destinations.

Safety

Bornholm is exceptionally safe. The Hammershus ruins have unfenced drops and uneven medieval stone surfaces requiring care; keep children close to cliff edges. Cycling the island is generally safe on dedicated paths, though some roads are narrow. Weather can change rapidly in the Baltic; a light layer is advisable even in summer.

Currency and Language

Denmark uses the Danish Krone (DKK). As of 2025–2026, approximately 6.9 DKK equal one US dollar. Credit cards (Dankort, Visa, Mastercard) are universally accepted in Denmark, including in small shops and cafés. Cash is increasingly uncommon but available at ATMs in Rønne.
