About Tromsøya

Tromsøya is the island in northern Norway that contains the central part of the city of Tromsø. It sits well above the Arctic Circle and is the urban core for the surrounding municipality.

On the island are Tromsø’s main streets, museums, shops and cultural institutions concentrated within a compact urban area, making it the primary base for visitors. Green spaces and short trails such as the Prestvannet reserve provide quick access to nature without leaving the island.

Tromsø developed as a regional centre for trade, fishing and Arctic expeditions from the 18th century onward; the island concentrated port and municipal functions as the town expanded. The University and modern infrastructure established Tromsø as a contemporary research and cultural centre for northern Norway.

Tromsøya sits in Troms county (now part of Troms og Finnmark) and is connected to the Norwegian mainland by bridge and tunnel. Its latitude places it well north of the Arctic Circle, making it one of the world’s northernmost significant urban centres.

  • Arctic daylight conditions: Located north of the Arctic Circle, the island experiences the midnight sun in summer and polar night in winter, making seasonal daylight extremes a defining feature for visitors.
  • Transport links: Connected to the mainland by the Tromsø Bridge and the Tromsøysund Tunnel, both of which provide the principal road links for vehicles and public transport.

What to See#

  • Tromsø city centre: Tromsø city centre contains the main pedestrian streets, shops, the cathedral and waterfront quays that form the island’s urban core.
  • University of Tromsø (main campus): The University of Tromsø (UiT) main campus is located on the island and is a major local employer and cultural hub with research facilities related to Arctic studies.
  • Prestvannet nature reserve: Prestvannet is a small lake and protected nature reserve on the island used for birdwatching and short nature walks within the urban area.

Getting There & Around

How to Get to Tromsøya

Tromsøya is the island that contains central Tromsø and is linked to the mainland by the Tromsø Bridge (Tromsøbrua) and the Tromsøysund Tunnel; the E8 road uses these connections. Tromsø Airport (TOS) is on the mainland roughly 4-5 km from the city centre.

Regular airport buses (Flybussen) and local bus services run between the airport and Tromsø city centre; once you arrive by bus or car the central harbour and pedestrian streets are a short walk from the main stops.

Tips for Visiting Tromsøya

  • If you want panoramic views of Tromsø and the surrounding fjords, cross the Tromsø Bridge and take the Fjellheisen cable car (on the mainland side at Tromsdalen) for the easiest access to the viewpoint.
  • For Northern Lights photography or darker-sky viewing, plan to leave the city center-light pollution on Tromsøya is significant, so head to the island's western or eastern shores (or cross the bridge) after dark.
  • The island hosts Tromsø Airport and the city centre close together, so time arrivals/departures knowing transfers on and off the island are short; aim to explore the shoreline paths (for example Telegrafbukta) at sunrise or sunset, when crowds are lowest and the light is best.
