Gluggafoss, also known as Merkjárfoss, is a stunning waterfall located in southern Iceland. Standing at approximately 52 meters tall, it features two main drops that cascade into a narrow recess below. What makes Gluggafoss unique is the holes and tunnels formed by the river through the soft palagonite rock, creating "windows" that allow observers to see the water flow partially obscured. Visitors can get up close to the waterfall by following small trails on the adjacent hills, offering a breathtaking view from both above and below. This natural wonder is definitely worth a visit for anyone exploring the beautiful landscapes of Iceland.
