Öxarárfoss is a cool waterfall in Þingvellir National Park, Iceland. It's like nature's own little show, with water cascading down the cliffs and forming a pool at the bottom. In winter, it freezes over, making it a popular spot for ice climbers (but only if you're a pro!). Plus, the park has some historical significance as the original site of the Icelandic parliament. So, if you're into stunning landscapes and a bit of history, Öxarárfoss is definitely worth checking out!
