Ronne Cruise Port: Pier 37, Buses and Hammershus

Almost everything worth seeing on Bornholm is somewhere other than Ronne. The ship ties up in the island’s capital, and the castle ruin, the round churches, the smokehouses and the famous sand are all a bus ride away across a 527 square kilometer island.

That single fact decides your day at the Ronne cruise port, because you either commit to leaving town early or you accept a pleasant, low-drama walk around a small Danish harbor city. Both are valid, but choosing between them at 10am on the quay is not.

My quick take

Bornholm is one of the more rewarding Baltic calls and one of the easiest to waste. The berth is alongside, the walk into town is short and flat, and the island beyond is genuinely lovely if you actually go there.

If this is your first visit, I would go north to Hammershus. It is the largest castle ruin in Northern Europe, entry costs nothing, and it is the one thing on Bornholm that photographs exactly as good as it looks.

If you would rather not spend half the day on a bus, Ronne itself holds up better than most capital-of-a-small-island towns. Cobbled lanes, painted timber houses, a good museum, and a harbor that still works for a living.

The thing I would not do is try to combine Hammershus in the north with Dueodde beach in the southeast on one port call. You would see a great deal of Bornholm through glass and very little of it on foot.

The quick facts

• Where you land: usually Pier 37, the multipurpose quay, which the Port of Roenne lists at 370 meters long, about 1,215 feet, with 11 meters of water, roughly 36 feet. Smaller ships take Pier 31 to 32, a 220 meter cruise quay with 9 meters alongside.
• Dock or tender: Alongside at Ronne, every time.
• Into town: About 1.5 kilometers from the pier to the center of Ronne, roughly a mile, which is a flat 20 minute walk.
• Currency and language: Danish kroner, and Danish with excellent English everywhere.
• Time zone: Central European Time, UTC plus 1, moving to UTC plus 2 for daylight saving from late March to late October.
• How often the call is missed: Low (under 5%): swell or rough seas can make access unsafe.
• How busy it gets: the port scheduled 64 cruise calls for 2026, plus 19 tender calls elsewhere on the island. That is a real season but nothing like Copenhagen, and two ships on one day is uncommon.

How the berth actually works

Ronne is a commercial port that happens to take cruise ships, not a cruise terminal with some cargo attached. Pier 37 is a multipurpose quay used for other things when no ship is in, so what you step onto is working concrete rather than a terminal building.

There is no passenger terminal at all, which sounds worse than it is. The port provides fresh water, shore connections and waste reception at the quay, and Destination Bornholm meets arrivals with an information desk and maps, so the practical gap is smaller than the architecture suggests.

Walk off the pier, turn along the waterfront, and you are in Ronne in about 20 minutes on flat ground. The route is not scenic for the first stretch, because you are walking past the business end of a Baltic freight port.

Getting around Bornholm without a tour bus

Bornholm has a proper public bus network, and it is the single most useful thing to understand about this port. BAT runs regional routes numbered 1 to 10 that all radiate out of Ronne, plus city routes 22 and 22C inside town.

Tickets come through the Rejsebillet app, from clip cards sold at tourist information, or in cash on the bus. Day passes exist in 1, 4 and 7 day versions, and for a port call the single day pass is almost always the right purchase.

The catch is frequency rather than coverage. Rural Bornholm buses are timed around ferries and school runs, not around a ship that leaves at six, so the return journey is the one you need to check first.

The mistake people make at the Ronne cruise port

The common error is treating Bornholm as a town call when it is an island call. People stroll into Ronne, decide by lunchtime that they want to see a round church after all, and discover that the bus timings no longer allow it.

The second error is underestimating how far north Hammershus sits. It is at the very top of the island, and getting there and back eats a large share of a standard port day, which is precisely why the ship tours exist.

Decide your shape before the gangway. Either you are an island person today or a town person today, and both plans work as long as you are not switching between them at noon.

It helps that Bornholm is never crowded by Baltic standards, with more than 60 calls and around 73,000 cruise passengers recorded in 2024. Over 80 percent of them arrived outside the Danish peak summer, and the 2026 season again runs April to October.

Best things to do from the Ronne cruise port

Hammershus castle ruin

Hammershus stands on a headland at the northern tip of the island and is the largest castle ruin in Northern Europe. The Danish Nature Agency confirms that the ruins are open around the clock all year and that entry to both the ruins and the visitor center is free.

The visitor center below the site has a restaurant, a shop and a permanent exhibition, and parking there costs 35 kroner for six hours during the main season. The caveat is the climb, since the route up to the ruin is steep and paved in uneven medieval stone.

Osterlars round church

Bornholm’s four round churches are the island’s signature, and Osterlars is the largest of them. It probably dates to around 1150, it was built to be a fortress as much as a church, and it takes about 120,000 visitors a year.

Admission is 30 kroner and you can climb up into the rafters, which is the part people remember. It is a working parish church, so services close it to visitors without much notice.

Bornholm Museum in Ronne

If you stay in town, the Bornholm Museum is the best hour indoors on the island. Three floors cover the island’s early history, Bornholm shipping, the Second World War, and a collection of local grandfather clocks.

Admission is 100 kroner, free under 18, and a 175 kroner combined ticket covers four museums for a week if you are staying longer. Watch the hours, because outside the late June to early August peak the museum keeps short afternoon opening and closes on Sundays.

Gudhjem, the smokehouses and the craft towns

Gudhjem and Svaneke on the east coast are the pretty ones, and they are where the smokehouses with their white pyramid chimneys still turn out Baltic herring. Bornholm is a designated World Craft Region, and the ceramics and glass studios are the real thing rather than a souvenir shelf.

The east coast is a bus ride from Ronne, so treat it as your one destination for the day rather than a stop on a circuit. Many workshops keep artisan hours, meaning they open when the maker is there.

Walk Ronne itself

Ronne is a small, dense, genuinely old harbor town of cobbled streets and painted half-timbered houses, and it takes about two hours to walk properly. It is the island’s capital, its ferry gateway and its only real urban center, which gives it more life than a tourist town would have.

Bornholm’s airport sits about 6 kilometers away, roughly 4 miles, and the ferries to Sweden, Germany and Zealand come and go all day. On a quiet spring call, the busiest thing in Ronne may well be the ferry terminal rather than your ship.

Fun fact: Hammershus once served as a prison for Leonora Christina, daughter of King Christian IV, who was held there with her husband in 1660 and 1661 after a treason case and made a failed escape attempt. The Danish Nature Agency’s own exhibition at the site is titled The Hated Castle, which tells you how the locals felt about the place that taxed them.

A realistic word on accessibility

The berth itself is about as good as European ports get for step-free access. You are alongside on a long, flat, modern quay with no tender, no stairs and no gradient between the gangway and the coach parking.

Beyond the quay it becomes mixed quite quickly. Central Ronne is compact and mostly flat but heavily cobbled, and the historic lanes have the narrow, uneven surfaces you would expect of a town laid out long before curb cuts.

Hammershus deserves a specific warning, because the Danish Nature Agency states plainly that the ruin is not suitable for wheelchairs or strollers due to the steep, uneven approach. The visitor center and its paths are accessible and there is free parking for disabled vehicles, so the exhibition and the view are reachable even when the castle is not.

When to go, and the weather

Bornholm sits far enough east in the Baltic to have its own relatively dry, sunny microclimate, which is why Danes treat it as a summer island. Annual rainfall is around 485 millimeters, about 19 inches, and the island averages roughly 2,065 hours of sunshine a year.

Summer highs sit in the low 20s Celsius, around 70 Fahrenheit, and the sea peaks near 18 Celsius in August, about 64 Fahrenheit. April and October calls are cooler and can be genuinely cold on an exposed quay, so bring a windproof layer regardless of what the forecast promises.

The thing that catches people is wind rather than rain. Bornholm is a low island in an open sea with no shelter to speak of, and a stiff Baltic breeze on the north coast at Hammershus will feel nothing like the temperature you left at the pier.

Quick answers

Do cruise ships dock or tender at Ronne, Bornholm?
Ships dock alongside at Ronne, normally at Pier 37, a 370 meter quay with 11 meters of water. Tendering only applies to small expedition ships that call at Gudhjem or Christianso instead of Ronne.

How far is Ronne town from the cruise pier?
The center of Ronne is about 1.5 kilometers from the pier, roughly a mile, which is a flat walk of around 20 minutes. A shuttle is normally provided and a tourist information desk with free maps meets arriving ships.

Can you visit Hammershus from a cruise ship in Ronne?
Yes, and entry to both the ruins and the visitor center is free, but Hammershus is at the far northern tip of the island. Allow most of your port day for the round trip by ship excursion, public bus or taxi.

Is there public transport from Ronne cruise port around Bornholm?
Yes, BAT runs regional bus routes 1 to 10 out of Ronne to the rest of the island, with 1, 4 and 7 day passes available. Buy through the Rejsebillet app or pay cash on board, and check the return timing before you commit.

What currency do you need on Bornholm?
Denmark uses the Danish krone, not the euro, and Bornholm is no exception. Cards and phone payments work almost everywhere, so most cruise passengers never need cash at all.

The last word

The only decision that matters at Bornholm is whether to leave Ronne. Make it before you go to bed the night before, buy your bus pass or book your tour accordingly, and the island will be one of the best days on a Baltic itinerary.

Stay in town and you get a small, real Danish harbor city, a very good museum and a two hour walk that costs nothing. Go north and you get a free castle ruin on a headland that would be mobbed if it were anywhere more convenient.

Bornholm sits on the same itineraries as the big names, so it is worth reading it against its neighbors in our guide to Denmark’s cruise ports and alongside the Copenhagen cruise port, which is where most Baltic sailings that include Ronne begin. The other Baltic island call worth comparing is Visby on Gotland, which does the medieval walled town thing that Ronne pointedly does not.

And if you are the sort of passenger who wants to step off and simply walk, Ronne earns a place on any list of genuinely walkable cruise ports. Just be honest with yourself about whether walking the capital is really what you came to Bornholm for.
