🌍 When to go to Iceland
Summer brings long daylight hours, accessible highland roads and the mildest weather for the Ring Road and waterfalls. Winter is dark, cold and stormy, though it is the only time to chase the northern lights, with September to March offering aurora chances.

Cold-weather camping & RV kit for Iceland
Nights here drop near or below freezing even inside the recommended season — usually because of altitude, not latitude. The gear that matters is what keeps heat in overnight and water lines flowing.
- View ↗0°F sleeping bagA 30°F bag is the single most common mistake at altitude. Rated to 0°F leaves headroom.
- View ↗Insulated pad, R-value 6.5Most heat is lost downward. R-value above 5 is the line between a cold night and a warm one.
- View ↗Portable propane heater9,000 BTU with oxygen depletion sensor — the standard for tents and small RV interiors.
- View ↗Reflective window insulationRV windows are the biggest heat leak. A roll cut to size costs less than one cold night.
