Den Våde Ovn Sea Cave, Hammershus
A dramatic 70 m sea cave hidden in Bornholm’s granite cliffs beneath Hammershus, Den Våde Ovn is reached only by boat and reveals the island’s wild Baltic coastline up close.
Den Våde Ovn is a dramatic sea cave carved into the rugged granite coast beneath Hammershus on Bornholm’s northwestern shore. Accessible only by boat, this roughly 70 m deep cleft cuts straight into the coastal cliff, creating an echoing rock corridor where green-tinged light, cool spray and the surge of the Baltic Sea combine. Boat trips from nearby Hammerhavn glide along towering cliff walls, past sculpted formations and bird ledges, before carefully nosing into the narrow opening of the cave itself for an unforgettable close-up of Bornholm’s wild coastline.

Local tips
- Wear a windproof layer; even on sunny days, the temperature and wind chill drop noticeably once the boat noses into the shaded cave and along the exposed cliffs.
- Sit on the seaward side of the boat for unobstructed views into Den Våde Ovn and of the neighbouring cliff formations like Løvehovedet and Kamelerne.
- If you are sensitive to motion, consider a morning trip when the sea is often calmer, and bring any seasickness remedies you might need for the 40–60 minute cruise.
- Protect cameras and phones with a strap or dry bag; light spray is common near the cave entrance and when the swell reflects off the rock walls.

Getting There
-
Boat from Hammerhavn
The most common way to experience Den Våde Ovn is on a scheduled sightseeing boat from Hammerhavn, the small harbour at the foot of Hammershus. Traditional wooden boats generally operate in the warmer months, with trips of around 40–60 minutes that include the cave and nearby cliff formations. Expect departures every 30–60 minutes in high season, with reduced frequency outside peak times. Adult tickets are typically around 100 DKK and children about 50 DKK, payable at the harbour or on board. Sailings depend on sea and wind conditions, so operations may pause in rough weather.
-
Guided coastal boat tour from Allinge
From Allinge, several local operators offer seasonal coastal boat tours that run along Bornholm’s northwestern shore toward Hammershus and Den Våde Ovn. These trips usually last 1.5–2 hours, combining commentary about the fortress, sea caves and rock formations. Prices commonly range from 200–350 DKK per adult depending on duration and boat type. Departures are less frequent than from Hammerhavn and may require advance booking, especially in July and August. Tours may be cancelled or rerouted if swell conditions make entering the cave unsafe.
-
Sea kayak excursion along the Hammeren coast
Experienced paddlers can join a guided sea kayak tour along the Hammeren coastline, typically starting from nearby bays on the north coast. These outings often last 3–4 hours and, in suitable conditions, may approach the entrance of Den Våde Ovn for a close look at the rock walls and surge of the sea. Guided tours usually cost in the region of 400–700 DKK per person, including equipment. Participation requires good mobility and comfort on open water, and trips are highly weather-dependent, with guides adjusting routes to wind, swell and group ability.

A hidden sea cave beneath Hammershus
Den Våde Ovn is a long, narrow sea cave sliced into the steep granite coastline between Allinge and the ruined fortress of Hammershus on Bornholm’s wild northwest corner. From the clifftops above, you might never guess that a 70 m deep corridor has been hollowed out by centuries of wave action, but from the water the entrance appears as a dark vertical slit in the rock, framed by sheer walls and lichen-streaked stone. The cave’s name, literally “the Wet Oven,” hints at its shape: like a rocky oven or chimney filled with surging Baltic water. Swells roll in and out of this confined space, amplifying the sound of the sea and sending spray up the walls. It is a striking natural counterpoint to nearby Hammershus, whose medieval ruins watch over the same stretch of coast from high above.Bornholm’s granite coast shaped by the Baltic
This part of Bornholm is famous for its dramatic granite, and Den Våde Ovn is one of the clearest demonstrations of what wind, waves and winter ice can do to hard rock. Vertical fractures in the granite gave the sea a starting point, and over thousands of years the cave was slowly enlarged as storms forced water, pebbles and sand into the crack. Around the cave, the coastline is a gallery of sculpted formations with names like Løvehovedet (the Lion’s Head) and Kamelerne (the Camels). Jagged headlands, boulder-strewn shores and sheer cliffs provide nesting ledges for seabirds and striking views in every direction. Seen from a small wooden boat at water level, the scale of the cliffs and the depth of the cave feel particularly impressive.Experiencing the cave from the water
There is no path or platform leading into Den Våde Ovn; the only way in is by boat. Traditional wooden sightseeing boats depart from Hammerhavn and follow the cliff line, edging as far into the cave as sea conditions and safety allow. On calm days you may glide deep into the shadowed interior; when swells are larger, the boat typically pauses near the entrance so passengers can still appreciate the echoing acoustics and sense of enclosure. Inside, the temperature often drops noticeably and the light changes from open-sky brightness to a muted, greenish glow reflected off the water. You can watch reflections dance on the rock walls and hear the slap of waves amplified by the stone corridor. Even without stepping ashore, the short passage into the cave feels like entering another world, hidden just behind the sunlit cliffs.Wildlife, seasons and changing moods
Den Våde Ovn and the surrounding coast support a variety of birdlife, especially during the warmer months when ledges above the waterline are busy with nesting and resting seabirds. The cliffs are streaked with hardy vegetation that clings to cracks in the rock, and in summer the contrast between bright green growth and grey granite is particularly striking. Conditions on the water change quickly with the season. In calm summer weather the approach to the cave feels tranquil, even meditative, while in windier periods the same landscape takes on a more dramatic, elemental character as waves boom into the confined space. Boat operators adjust how far they enter the cave depending on swell and visibility, so each visit can feel a little different.Planning a visit along the Hammeren coast
Most visitors combine a boat excursion to Den Våde Ovn with time exploring the wider Hammeren and Hammershus area. From the sea you gain a low, close-up perspective on the cliffs, while trails on the heights above offer sweeping views over the Baltic and the route the boats take. The experience does not require special equipment beyond weather-appropriate clothing; the boats provide seating and a relatively gentle pace along the shore. Because access to the cave is entirely dependent on boat operations and sea conditions, it is worth allowing some flexibility in your plans. Mornings and evenings can feel especially atmospheric on the water, with softer light on the rock faces, while midday trips emphasise the stark colours and sharp contrasts of granite, sea and sky. Whichever timing you choose, the combination of Hammershus, Hammerhavn and this concealed sea cave makes for a distinctly Bornholm coastal experience.Iconic landmarks you can’t miss
