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.
- 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.
- 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.
- 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.
- 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.
