Do I really need rain pants?

Yes. Weather in the fjords changes in minutes. If you are hiking for 6+ hours, you will eventually encounter horizontal rain, and denim or standard trousers will soak through instantly.

Avoid them for serious fjord hikes like Preikestolen or Trolltunga. You need the traction of a lugged rubber sole and the ankle stability to prevent injuries on wet, mossy granite.

How to pack for a fjord hiking trip in Norway

Pack for four seasons in a single day by using a three-layer system: a synthetic base, an insulating mid-layer, and a waterproof hard shell. Never rely on cotton, as it stays cold and wet when it inevitably rains.

Master the base layer. Wear thin merino wool against your skin. It wicks moisture while you sweat and keeps you warm even if it gets damp. Bring two tops and one bottom for a 5-day trip.
Select your mid-layers. Pack one lightweight fleece for active hiking and one down or synthetic 'puffy' jacket for when you stop at viewpoints. You will need these to trap heat during wind-exposed summits.
Prioritize the outer shell. Do not skimp on rain gear. You need a jacket and trousers with a high waterproof rating (minimum 10,000mm) and taped seams. If it doesn't say 'waterproof,' it will fail you in a Norwegian mountain downpour.
Choose the right footwear. Bring broken-in, waterproof hiking boots with ankle support. Fjord trails are often muddy, rocky, and uneven. Wear wool hiking socks; bring one pair per hiking day to prevent blisters.
