Icelandic Caves & Geothermal Wonders

Southern Iceland’s geothermal landscape features the Great Geysir and the reliable Strokkur geyser, which erupts every few minutes. This selection includes the Reykjadalur valley, where a warm river allows for natural bathing, and the silica-rich, turquoise waters of the Blesi hot spring. Subterranean highlights range from the 9,000-year-old Gjábakkahellir lava tube to the man-made Laugarvatnshellir, inhabited by families until 1921. The list also covers the distinct basalt column caves found along the black sand beaches near Vík.
