Ylläs slope angle map
Ylläs is a 719 m fell, an open treeless hill, in Kolari, Finland, between Äkäslompolo and Ylläsjärvi; the summit and ski resort are outside Pallas-Yllästunturi National Park; the fells to the north are inside. Most of Yllästunturi is uncoloured on the slope angle map; the most 30° and steeper terrain is at Pirunkuru and on Kellostapuli.
How steep is the terrain around Ylläs?
Around the 719 m summit of Yllästunturi, the map is mostly uncoloured: under a fifth of the terrain is 20° or steeper, most of it in the blue 20–24° class, with the most colour on the south slope. On the east slope of Kellostapuli about a third of the terrain is coloured, and the steepest class that appears is 35–39°. Below the southern top of Kesänkitunturi, the Pirunkuru gorge is the densest patch of colour in the area: more than half of the terrain around it is 20° or steeper, and west of the gorge about a third is 30° or steeper. Lainiotunturi shows colour on nearly half of its east slope and almost none on the west; Kukastunturi shows only the 20–24° class.
Planning a trip to Ylläs: zones, access rules and slope angle
Skinning is allowed only outside the resort's groomed pistes and lift lines; for ski touring and freeriding into the park, transceiver test stations are at the bottom of Varkaankuru and at the Kesänkijärvi car park. From Keskinen laki northwards the fells are in Pallas-Yllästunturi National Park, where you may move freely on foot and skis outside restriction zones; in the 44 ha Varkaankuru zone only the marked trail may be used from 1 May to 30 November. On the map, look closely at the steep walls at the bottom of Varkaankuru, the slopes above Pirunkuru and Lake Kesänkijärvi, and the terrain between the ski area and the wild fells.
Where to check the avalanche forecast for Ylläs
Ylläs lies in the Finnish Meteorological Institute (FMI) forecast region Ylläs-Levi: the forecast runs in winter, from December or January to late April, and applies to unmanaged natural slopes only, not to groomed pistes. Ski Patrol Ylläs also publishes a local forecast for the seven fells of Ylläs; the two can differ temporarily because the FMI region is wider. Avalanches occur on the wild fells every winter; FMI's page shows an avalanche crown photographed on Kesänkitunturi on 20 March 2025.

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.
