Iceland's tallest waterfall descends gracefully in streaming ribbons down a 200 meter (658 ft) drop into a massive canyon adorned in lush green moss. Located near Hvalfjordur Fjord (Whale Fjord), Glymur waterfall is linked to a local folkloric tale about a mythical whale that swam up the waterfall into the lake at the top where, eerily enough, whale bones have been found.
