Iceland's weather can change quickly, so layering your clothing is a must. We suggest dressing in warm, waterproof layers, including a waterproof jacket, sturdy footwear, and a hat and gloves to keep you comfortable in any conditions. Taking an extra pair of warm socks with you is also never a bad idea.
Make sure to bring a warm jacket in winter, especially for northern light tours as it can get cold standing outside on crisp winter nights.
Be aware that inland Iceland is usually colder than the Reykjavík area.
