Essential Gear for Hiking in Iceland

You need a three-layer clothing system—base, mid, and waterproof shell—to handle unpredictable weather, plus sturdy, broken-in waterproof hiking boots. Focus on synthetic or wool materials, as cotton will keep you cold and wet if it gets soaked.

  1. Master the layering system. Wear a moisture-wicking base layer (merino wool), a heat-trapping mid-layer (fleece or light down), and a high-quality windproof and waterproof outer shell. Do not wear cotton.
  2. Select the right boots. Bring mid- or high-cut hiking boots with ankle support and a stiff sole. They must be waterproof, as you will likely cross streams or trek through mud.
  3. Prepare for wind and rain. Pack a pair of dedicated waterproof hiking pants to wear over your leggings or trousers. A rain poncho is useless in Icelandic wind; get a jacket with a hood that can be cinched tight.
  4. Pack for the sun. Even if it is cloudy, the UV index can be high. Bring polarized sunglasses and SPF 50 sunscreen; the reflection off glaciers and black sand beaches is intense.
Can I get away with sneakers for hiking in Iceland?
Absolutely not. The terrain is jagged volcanic rock, slippery mud, and deep moss. Sneakers offer zero ankle support and will be ruined by water and grit within two hours.
Do I need a heavy winter parka in July?
No, but you need a packable insulated layer (puffy jacket) to put on during rest breaks, as temperatures can drop to 5°C (41°F) even in summer when the wind picks up.
Are jeans ever okay for hiking?
Never. Once jeans get wet, they stay wet, heavy, and cold. They are a liability in Icelandic weather.
