Oslofjord cruises and island hopping: Ruter ferries, fares, and sightseeing boats

In this guide

💡 The Short Version: The inner Oslofjord islands are served by the city transit system. Ruter ferry line B1 leaves year-round from City Hall Pier 4 (Rådhusbrygge 4) at Aker Brygge for Hovedøya, Lindøya, Gressholmen, Bleikøya and Nakholmen on an ordinary NOK 46 Zone 1 single, which the Oslo Pass covers. Hovedøya is ten minutes from the pier, with the ruins of a 12th-century English Cistercian abbey and sheltered beaches. Sightseeing boats leave from neighbouring piers: NOK 362 for a wooden sailing ship or NOK 690 for a silent hybrid-electric catamaran. Or book a tour: a 2-hour guided cruise on a silent electric shipad from NOK 587 has live commentary from the guides, and the 1.5-hour audio-guide cruisead from NOK 430 is the cheaper option, so you need not work out the public ferry timetables.

⚠️ You cannot buy tickets on the islands. Buy through the Ruter app, or get a physical card at a mainland convenience store, before boarding. Don’t miss the last boat: there is no night service or water taxi on the fjord, and a sea-rescue pick-up is costly.

Public ferries vs commercial sightseeing cruises

Take the public ferry to explore the islands on foot, or a sightseeing cruise for narration from the water. Both leave from the quays beside Rådhusplassen (City Hall Square).

The public ferries work like city buses: scan your phone ticket at the shore gate, board, and get off at any island pier. A valid Ruter ticket or an active Oslo Pass covers every public island crossing.

Exploring the islands: stops and highlights

There are no cars on the inner islands. They range from medieval abbey ruins to summer cabin colonies and bird reserves.

Hovedøya: medieval cloister ruins and swimming bays

Hovedøya is 1.5 kilometres south of City Hall, under ten minutes away on Line B1. From the pier, gravel paths lead through pine and oak woods to the ruins of Hovedøya Abbey (Hovedøya kloster).

English Cistercian monks from Kirkstead Abbey in Lincolnshire founded the monastery in May 1147 at the invitation of the Bishop of Oslo. It lasted nearly four centuries, until 1532, when the abbot backed Christian II during a political crisis. The Danish commander of Akershus Fortress sacked it, burned its timber roofs and seized its estates for the Crown. The surviving stone walls, chapter house and cloister garth still show the layout of the abbey.

Also on Hovedøya:

• South-facing beaches: Grassy slopes drop to sheltered pebble and sand beaches, warm enough for swimming from late June to August.
• Napoleonic cannon batteries: Two stone artillery redoubts built between 1808 and 1814 stand on the eastern hilltops, built to defend Christiania harbour against British warships in the Gunboat War.
• Klosterkroa Café: A summer café near the monastery serving coffee, soft drinks, waffles and open sandwiches.

Lindøya: red and yellow cabin colonies

Lindøya is covered with roughly 300 small wooden summer cabins from the 1920s (hytteliv is Norwegian cabin life). Heritage rules limit their colours to Falun red, ochre yellow and forest green, with white window trim.

The island has two ferry piers on opposite sides:

• Lindøya vest (West): Closest to the bathing jetties and swimming ladders, and the small seasonal shop and café.
• Lindøya øst (East): Looks over the inner bay towards Bleikøya and Nakholmen.

A gravel path links the two piers in a 15-minute walk through narrow cabin lanes lined with lilac and wild roses. The southwest nature reserve protects limestone outcrops and rare plants.

Gressholmen, Heggholmen, and Rambergøya

These three islands were once separate and are now joined by narrow stone causeways, giving one walking area:

• Heggholmen Lighthouse: A small timber lighthouse from 1826 on the northern spit of Heggholmen.
• Seaplane base: In 1927 Gressholmen became Norway’s first municipal airport for floatplanes. The hangar and harbour ramp still stand near the eastern shore.
• Gressholmen Kro: A restaurant open in summer, serving local seafood, craft beer and baked goods in an outdoor garden.
• Rambergøya Nature Reserve: The southern arm has mudflats and shallow lagoons protected for migratory wading birds and nesting eider ducks.

Bleikøya and Nakholmen

These are the quietest of the islands:

• Bleikøya: A steep central ridge and 90 private summer cabins. The northern end is a bird sanctuary where gulls, terns and eiders nest from 15 April to 15 July, and landing in the reserve is forbidden in those dates.
• Nakholmen: Just west of Lindøya, with about 180 wooden cottages and a navigation beacon that guides ships into the main harbour channel.

Langøyene: swimming, saunas, and overnight camping

Langøyene is the island for tent camping. It was two islands joined by landfill in the early 20th century, and after a long clean-up it reopened with modern facilities.

It has:

• A sandy beach with shallow, family-friendly water.
• Grassy tent-camping zones with freshwater taps and toilet blocks.
• Recreation lawns, beach volleyball courts and seasonal kiosks.
• Summer transport on Ruter Line B2, which runs from late May to early September.

Fares, ticketing, and practical ferry rules

Fare table (Ruter Zone 1)

All inner island public ferries fall within Ruter Zone 1. No surcharge applies for water crossings.

Essential ferry rules

1. Buy tickets before boarding: The ferries and island piers have no ticket machines or counters. Buy in the Ruter app or carry a card bought on the mainland (Narvesen, 7-Eleven or Oslo Central Station). Inspectors make spot checks, and travelling without a valid ticket is an on-the-spot fine of NOK 1,150.
2. 60-minute validity: A single ticket lasts 60 minutes from activation. If you take a tram or metro to Aker Brygge and board the ferry within that hour, you need no second ticket.
3. Take your rubbish back: The islands have few bins. Carry wrappers, cans and packaging back to the mainland.
4. No fires: Open fires and disposable foil barbecues (engangsgrill) are banned on all islands because of wildfire risk on the rocky pine ground. Only the permanent concrete grills may be used.
5. Dogs: Keep dogs on a short leash on all islands to protect nesting birds.
6. Winter timetables: From late October to late March Line B1 runs about 7 to 8 loops a day. Check the last return boat in the Ruter app before you leave the mainland.

• 11:35: Catch the next B1 departure from Hovedøya to Lindøya øst.

Planning your day on the water

To ensure a seamless fjord outing, keep these practical points in mind:

• Food and water: Outside peak July weekends the island cafés keep short hours. Bring water and a packed lunch from a supermarket such as Kiwi or Rema 1000 near Central Station.
• Footwear: Trails are gravel, earth and uneven granite slabs. Wear trainers or trail shoes, not thin sandals.
• Harbour saunas: A five-minute walk east along the quay brings you to the floating saunas at Langkaia and Sukkerbiten; see floating saunas in Oslo.
• Mainland sights: The ferry pier is within five minutes’ walk of Oslo City Hall and the National Museum, so a morning on the islands and an afternoon in a gallery fit together.
• Further afield: See day trips from Oslo, or go south to the timber town and fortress in Drøbak and Oscarsborg Fortress.

Common questions

How much does the Oslofjord public ferry cost?

The island ferries are part of the Ruter city network. A Zone 1 single costs NOK 46, and Ruter sells 24-hour and 7-day passes in its app. The Oslo Pass covers all Ruter island ferries. Tickets are not sold on the islands, so buy before boarding.

Where do the Oslofjord island ferries depart from?

From Rådhusbrygge 4 (City Hall Pier 4) at the eastern edge of Aker Brygge, in front of Oslo City Hall. Line B1 runs year-round to Hovedøya, Bleikøya, Gressholmen, Lindøya and Nakholmen. In summer line B2 also serves Langøyene.

How often do the island ferries run in winter?

Line B1 runs all year, but departures drop from every 20 to 30 minutes in peak summer to roughly 7 or 8 a day in winter. Timetables change in late October and late March.

What happens if I miss the last ferry back to Oslo?

There are no water taxis in the inner Oslofjord and no night service. If you miss the last boat, you have to call the Norwegian Society for Sea Rescue (Redningsselskapet) or a private charter company, and a rescue pick-up is expensive. Check the last return time in the Ruter app before you go.

How much is a commercial Oslofjord sightseeing cruise?

A two-hour cruise on a wooden sailing ship such as Båtservice's S/S Helena costs NOK 362. A two-hour silent electric fjord cruise with Brim Explorer costs NOK 690, with indoor lounges and open observation decks.
