A 165-km, ten-day wilderness trail from the ice sheet to the coast with huts, reindeer and no roads.

Two-week trek up the Baltoro Glacier to the foot of the world’s second-highest peak.

The "Mountains of the Moon" — glaciers on the equator, giant lobelias and bogs on a multi-day trek towards Margherita Peak.

Rhyolite mountains streaked orange, green and pink, with a natural hot river to soak in after the walk — the start of the Laugavegur trail.

Turquoise alpine lake at 3,560 m, the classic Karakol trek.

The "troll’s tongue" rock ledge jutting 700 m above lake Ringedalsvatnet.
