Your full-day adventure begins with pickup from your hotel in central Reykjavik. Soak up the scenery as you leave the city behind and head inland to the UNESCO World Heritage Listed Thingvellir National Park. As you pass through ancient lava fields, listen to your guide share insight into Iceland’s fascinating geology, as well as the park’s unique location, which sits at the meeting point of the North American and Eurasian tectonic plates. Hop out to admire the dramatic landscapes caused by the drifting of the plates, then visit the site of the world’s first parliament at the heart of the national park. Continue the tour through the mountainous landscapes, passing by Lake Laugarvatn to reach the geothermal location of the geysirs. Upon arrival, enjoy the chance to admire the 'original geysir', after which all others were named. Even more impressive is the neighboring Strokkur geysir, which erupts every few minutes in a spectacular burst of water and steam. Afterwards, a short drive brings you to another awe-inspiring natural wonder, the mighty Gullfoss waterfalls. At the waterfalls, enjoy ample time to learn about and snap photos of the dramatic landscape. After an action-packed morning, it’s time to venture off-the-beaten-track and pay a visit to the beautiful Secret Lagoon. Located in the small village of Fludir, the lagoon is a perfect example of Iceland’s famous natural hot springs, with waters reaching temperatures of up to 104˚F (40˚C). Take some time to relax and unwind in the steamy pools, before climbing back on the bus for the return journey. On the way back to Reykjavik, make one final stop to admire the volcanic crater of Kerið. Back in the city, your tour ends with drop-off at your hotel.
