Customer Reviews

We joined a one day tour to visit the lava cave and got sprint today. Our tour guide was fantastic. He explained a lot of Icelandic nature alone the way and he took us for the hot spring first then a coffee break then visit the lava cave. The hike to the hot spring is very scenic. Beautiful green Icelandic landscape with geothermal activities along the way...The natural hot spring was so relaxing. My skin felt very soft afterwards. The lava cave is very cool as well... Overall a great day hiking, caving and enjoying hot spring.
