At 2469 meters, Galdhøpiggen is the highest moutain in Norway (indeed in Northern Europe) and many Norwegians aim to climb it at least once. There are two choices:
From Spiterstulen: 1300 m straightforward ascent from Spiterstulen mountain lodge, no glacier crossings and no technical sections. The initial 500 meters ascent takes you above the valley, then the snowfields begin and a considerable part of the rest of the hike is on snow.
Once at the summit, you see the hundreds of people coming up from the other track from the Juvasshytta. On a fine day, as it was when I walked up from Spiterstulen, it can get quite crowded at the summit. In Nepalese style there even is a coffee shop, accepting credit cards at the summit and the glacier guide I saw on the summit was Nepalese as well.
In fine weather Galdhøpiggen summit hike is a great hike, with fantastic views over large parts of Jotunheimen and numerous glaciers from the top.
Highlights: The summit: The views, the atmosphere, the coffee shop.
Difficulty: 4. A long, relatively steep with no exposure, no scrambling, but long sections on snow.
