Tromsø slope angle map
Tromsø is a city in northern Norway; its centre is on the island of Tromsøya, between the mainland at Tromsdalen and the larger island of Kvaløya. Fløya opposite the city is mostly uncoloured on the slope angle map, while most of the terrain around Tromsdalstinden (1238 m) and Store Blåmannen (1044 m) on Kvaløya is 20° or steeper.
How steep is the terrain around Tromsø?
Within 1.5 km of Tromsdalstinden (1238 m), the highest summit visible from Tromsøya, almost two thirds is 20° or steeper on the map, and the south side has the most terrain of 30° and steeper. Fløya opposite the city is mostly uncoloured; its colour sits mainly on the north and east sides, and the south side has little colour. In Tromsdalen the valley floor to the east is almost uncoloured, while both valley sides carry colour, more on the south side. Around Store Blåmannen (1044 m) on Kvaløya, more than four fifths is 20° or steeper, about a quarter is 45° or steeper, and on the west side nearly half is 40° or steeper. Solltinden on Ringvassøya is also mostly coloured.
Planning a trip to Tromsø: zones, access rules and slope angle
Hikers and snowshoers use Fløya, Storsteinen (cable car station, 421 m) and Tromsdalen; Tromsdalstinden is climbed and skied from Tromsdalen and Ramfjord. Ski tourers go to Kvaløya (Lille Blåmann from Håkøybotn) and through the Kvalsund tunnel to Ringvassøya. The Prestvatn protection area on Tromsøya bans motor traffic, camping and fires and closes a zone at its south end 1 May to 31 July; the west side of the Lyngen Alps in Tromsø municipality is in the Lyngsalpan protection area, which bans flying below 300 m. The map separates the Tromsdalen floor from its sides and shows the slope from the cable car plateau to Fløya's top.
Where to check the avalanche forecast for Tromsø
Varsom (NVE) publishes an avalanche forecast for the Tromsø region daily from 1 December to 31 May; it includes Tromsøya, Kvaløya, Ringvassøya, Fløya and Tromsdalstinden, which lies close to the Lyngen boundary. Ramfjorden, Breivikeidet and Lakselvbukt are in the Lyngen region. Visit Tromsø warns that coastal weather changes fast, strong wind builds slabs and cornices, and weak layers can persist into spring. The cable car operator says parts of Sherpatrappa lie in avalanche terrain and are mostly under snow and ice in winter.

How to read the slope classes
The colours start at 20°; the six classes are listed below. Terrain with no colour is below 20° or a gap in the source data. The map gives no point values: compare each colour with the legend, and zoom in, because when zoomed out each pixel shows the steepest value in the area it covers.
- 20–24° blue
- 25–29° light green
- 30–34° yellow
- 35–39° orange
- 40–44° red
- ≥45° magenta
Data and grid size
The slope classes are computed from the official elevation model named below, on a 2 m grid. They show terrain shape, not snow, weather or trail conditions.
