Gatklettur, also known as "Hellnar Arch," is a stunning natural stone arch located between Arnarstapi and Hellnar on the Snæfellsnes Peninsula in Iceland. This unique rock formation is a favorite spot for photographers due to its swirling patterns created by the ocean's constant erosion. Less crowded than other tourist sites, Gatklettur offers a peaceful and picturesque setting for visitors to enjoy. Accessible via a scenic hike from Arnarstapi, this hidden gem is definitely worth a visit for those seeking a tranquil and beautiful experience in Iceland.
