Your journey begins with a scenic 15-minute boat trip across the Holandsfjord, bringing you to the trailhead. This you have to pay for. The boat leaves from here: https://maps.app.goo.gl/boTdERaXifbFEy3H9?g_st=ic

The hike is a challenging one, so you'll want to be in good shape, but the path is well-trodden as you ascend towards the Tåkeheimen cabin, with the magnificent Engabreen glacier revealing itself behind you. The final push to the summit involves navigating rocky, unmarked terrain, but you will see where it is smart to go.

Hot tip: Book a night at Tåkeheimen cabin, then you have a lot of time to do the hike and explore the glacier.
