Iceland's Southern Coast is perhaps the most popular area in the entire country. Start your road trip by heading East from Reykjavik to see waterfalls like Öxarárfoss, Gulfoss, Faxifoss, and Bruarfoss waterfalls near Þingvellir National Park along with Haifoss, Hjalparfoss, Gjain, and Þjófafoss just further north. Then finish your day with Kerid Crater and Urriðafoss.
