Travel tips for Bornholm

A weekend is barely enough to do Bornholm justice; a week lets you enjoy it at a comfortable pace. This guide brings together the thirteen best-value sights on the island - deliberately broader than a pure beach list. Ten fine sandy beaches and rocky coves sit alongside three sights that stand for nature, history and views: the Hammershus castle ruin, the Hammeren lighthouses and the fortress island of Christiansø. The result is a mix of swimming, walking and culture that combines well into day trips. Distances are short - most sights are within half an hour's drive of the ferry port at Rønne.

The best-value sights at a glance

Top of the list is Hammershus, Northern Europe's largest castle ruin on a 74-metre granite cliff above the Baltic Sea. With around 400,000 visitors a year it is Bornholm's most-visited attraction, accessible year-round around the clock and free to enter, including the visitor centre - loveliest in the evening sun. Not far away tower the Hammeren lighthouses: Hammerfyr, 91 metres above the sea with views as far as Sweden, plus Hammerodde Fyr on the coastal path. Entry to Hammerfyr is free.

Very different in character is Christiansø, the car-free fortress island around 18 kilometres off the north-east coast. The 1684 sea fortress with its two tower museums is reached by ferry from Gudhjem - the only sight on this list that charges admission, and, with fares of 220 to 320 DKK depending on the season, also the one that takes the most planning. If you can fit it in, allow a full day.

Beaches are at the heart of the selection. On the fine-sand south coast lie Dueodde with its powder-fine sand, the sheltered family cove of Balka, and Sømarken and Boderne. In the north, the sandy beach at Sandvig near Hammershus stands out, while on the east coast there's the clear rocky cove of Hullehavn near Svaneke and the beach at Melsted near Gudhjem. Add to these the Rønne beaches, the long stretch of Store og Lille Sandkås, and the quiet Næs Beach near Allinge. Anyone interested purely in the coast will find the full picture - water quality, lifeguards and algae season - in the guide Beaches on Bornholm.

Free or ticketed - the prices

The good news first: eleven of the thirteen sights are completely free to visit. All ten beaches are open year-round at no charge, as are Hammershus with its visitor centre and Hammerfyr. Payment is only required for the ferry island of Christiansø and a few extra attractions located next to a beach.

In concrete terms, all prices in DKK: at Dueodde the beach itself is free, only the NATO lookout tower Bornholmertårnet charges admission (adults 125 DKK, children aged 4 to 12 75 DKK), and climbing the 47-metre Dueodde Lighthouse - Denmark's tallest - costs a small symbolic fee of around 10 DKK, cash on site. At Melsted the Melstedgård museum sits right next to the beach (adults 100 DKK, free under 18). At Balka Beach only the watersports rental is chargeable: windsurf sets from 150 DKK per hour, SUP from 125 DKK. And at Hammershus, parking during the season - from the Saturday before Palm Sunday to the autumn half-term - costs 35 DKK for six hours, while the disabled and coach car park P2 remains free year-round.

The Christiansø ferry, at 220 DKK (winter), 260 DKK (summer) and 320 DKK (peak season) for adults, is the only seasonally variable cost, plus a 10 DKK fuel surcharge per ticket since 7 April 2026. The two tower museums cost an additional 40 DKK for adults. Car parks clearly signposted as free of charge exist only at Sandvig and Hammerfyr; elsewhere, local signage applies.

Tips for combining sights

The north combines well into a single day: Hammershus, the Hammeren lighthouses and the sandy beach at Sandvig lie close together, along with the quiet Næs Beach near Allinge. In the south, beaches follow one after another - Dueodde, Sømarken, Boderne and Balka are all a short distance apart, ideal with children. The east coast, with Hullehavn near Svaneke and Melsted near Gudhjem, combines swimming with crafts and smokehouses.

Water quality is generally rated good to excellent; in hot weather with a sustained easterly wind, localised algae can appear, particularly at Melsted, Balka and along the shore at Hullehavn. Since the island is small and distances short, switching to the coast sheltered from the wind usually helps. Travellers without a car can reach most sights on the public bus operator BAT. Further suggestions are gathered in the guide Activities on Bornholm, and getting there - including bus and bike - is covered in the guide Getting there.
