Start your day by first seeing Seljalandsfoss, Gljufrabui, Skógafoss, and Kvernufoss waterfalls along the ring road. Also make sure you have time to discover the Sólheimajökull Glacier, Hjörleifshöfði Cave (Yoda Cave) and the Sólheimasandur plane wreck. Dyrhólaey has some of the best views and the Reynisfjara beach is a must see. The town of Vik is best for seeing Reynisdrangar as well.
