Gatklettur, also known as the Hellnar Arch, is a stunning natural rock formation located on Iceland's Snaefellsnes Peninsula, offering spectacular photographic opportunities. This iconic site is easily accessible via a short walk from a free parking area, making it ideal for solo exploration as part of a self-drive tour, though it's also a common stop on guided tours of the peninsula. There are no entrance fees, and a typical visit lasts 15-30 minutes for viewing and photography. While open year-round, visitors should be aware that winter conditions (snow, ice, strong winds) can make access and enjoyment challenging; the summer months offer the most favorable experience. The walking path to the arch is generally well-maintained but may include uneven terrain, which could limit direct wheelchair access, though good views are available from nearby vantage points. A popular café is located conveniently close by.
