What to pack for Iceland

The single most important rule for packing for Iceland: weather changes fast and you can get all four seasons in a single afternoon. Layering matters more than insulation, and waterproofs matter more than warmth. Pack like you're going on a hike in the Scottish Highlands and you'll be close.

The layering system

Build your wardrobe around three layers and you can adapt to almost any weather Iceland throws at you:

• Base layer: wicks moisture off your skin. Merino wool or synthetic; never cotton, which holds water and chills you. A long sleeve top and bottoms.
• Mid layer: insulates. Fleece (most versatile) or a light synthetic puffy. Bring two so you can stack them on cold days.
• Outer layer: blocks wind and rain. A waterproof, breathable shell jacket and shell pants. This is the single most important item on the list. Cheap rain jackets fail in Icelandic wind; spend on this one.

Year-round essentials

• Waterproof shell jacket and pants. Gore-Tex or equivalent. Will save you on at least one day per trip.
• Waterproof hiking boots. Mid-cut with ankle support. Iceland's "easy" trails involve more loose rock and stream crossings than you'd expect.
• Wool socks (3–4 pairs). Smartwool, Darn Tough, or similar.
• Swimsuit and quick-dry towel. For hot springs and pools, of which there are many. A microfiber travel towel saves space versus a standard towel.
• Sunglasses. Yes, even in winter — especially in winter, when there's snow on the ground.
• Reusable water bottle. Tap water is among the best in the world; you can fill up almost anywhere, including from many streams in the highlands.
• EU plug adapter (Type F). Iceland uses 230V / 50Hz with European-style plugs.
• Power bank. Cold drains phone batteries fast. A 10,000+ mAh bank covers a day of photography.
• Card with PIN. Iceland is nearly cashless. Some unmanned gas pumps require a chip-and-PIN card; Apple Pay is widely accepted.
• Sleep mask. If traveling in summer, the midnight sun makes a sleep mask invaluable. Many guesthouses lack blackout curtains.
• Earplugs. Wind in old buildings and campervans is louder than you'd expect.
• Small daypack. 20–30L for daily use on hikes and around stops.

Summer additions (June–August)

• Lighter mid-layers. Daytime can hit 15°C–20°C; you don't need a heavy fleece every day.
• Insect head net. Specifically for the Mývatn area, where summer midges can be aggressive. A $5 net saves a day.
• Sunscreen. Yes, the sun is real; the snow and water reflect it.
• Hiking poles if you plan to hike Laugavegur, Fimmvörðuháls, or any other multi-day route.
• Sandals or water shoes if you'll cross streams on foot or wade in hot rivers like Reykjadalur.

Winter additions (October–April)

• Heavy insulated jacket over the shell layer for aurora-watching and exposed walks.
• Thermal base layers (heavy weight). Both top and bottom.
• Two pairs of gloves: a thin liner that lets you operate a phone or camera, and a heavy mitt over the top.
• Beanie/wool hat and a buff or scarf. Cover your face when the wind blows.
• Microspikes or stabilicers. Slip-on traction for icy paths around waterfalls and parking lots. The single most-forgotten winter item; you can buy them at Icelandic gas stations and outdoor shops if you forget.
• Hand warmers. Disposable iron-oxide warmers are a lifesaver during long aurora stake-outs.
• Insulated/water-resistant winter boots. Your waterproof hiking boots may be too cold for prolonged standing in winter; consider a warmer pair if you'll be out at night.
• Headlamp. With short days, you'll often be walking from car to lodging in the dark. A small headlamp leaves both hands free.

Things travelers most often forget

• Earplugs and a sleep mask. The combination of midnight sun and windy old buildings is no joke.
• A second waterproof bag inside your daypack for camera gear and electronics. Driven rain finds its way through anything.
• Snacks for the road. Convenience stores between towns are limited and expensive. Bring trail mix, jerky, energy bars from home.
• A roll-top dry bag for wet swimsuits after hot springs.
• Quarters — or rather, króna coins — you don't need any. Iceland has effectively gone cashless. The card you tap on the bus in Reykjavík is the same one you use at the gas station in Egílsstaðir.

Things you probably don't need

• Heavy parka with arctic rating. Iceland is warmer than people expect. A good shell over insulation is enough except in extreme cold snaps.
• Bug spray outside the Mývatn area. Mosquitoes are essentially absent.
• Snake gaiters, bear spray, etc. No snakes, no bears. The most dangerous animal you'll meet is a sheep on the road.
• An umbrella. The wind will destroy it within 30 seconds. Use a hood.

Renting vs. buying in Iceland

Outdoor gear in Reykjavík is excellent but expensive. If you're missing something specific, 66°North, Cintamani, and Icewear all have flagship stores. For single-trip needs, several Reykjavík shops rent shell jackets, hiking boots, and sleeping bags at reasonable rates — cheaper than buying, useful if you're connecting from a warm-weather destination.
