The Vatnajökull Voyager trip offers a chance to see the south coast highlights in a day. Including a glacier hike on the Falljökull glacier and a boat ride on the Glacier Lagoon (Jökulsárlón). This is a fast paced trip for all fitness levels and those with perhaps limited time in Iceland. Unless you have walked on a glacier and seen the floating icebergs on the Glacier Lagoon up close, one could argue that you really have not seen Iceland.
