After being picked up from your accommodation, you will travel west to the historic area of Borgarfjörður, a region that can be regarded as the setting for most of the Icelandic sagas. First, visit the charming Glanni Waterfall and Deildartunguhver Geothermal Area. Afterward, you will see the great Hraunfossar, a series of waterfalls spread at a distance of around 900 meters. The waters flow out of the Hallmundarhraun, a lava field that was formed around 1,000 years ago during a massive eruption of a volcano lying under a Langjökull glacier. Rivulets streaming from the lava field create one of the most breath-taking views in Iceland, and just a few meters away, you will find another interesting waterfall.  The highlight of the tour is a visit to a colorful Vidgelmir lava cave. Just shy of 1,600 meters in length, the cave features amazing colors and lava formations that lurk in the depths of the earth. The area surrounding the entrance to the cave will allow you to realize just how powerful eruptions of volcanoes can be. Lastly, visit the Reykholt historic site where you can learn about the history of Iceland and see Snorralaug, small hot spring used by local people since the 12th century. This place was first mentioned in medieval writings OF Snorri Sturluson, the famous Icelandic poet, and politician who used to bathe there.
