Marvel as the active hot spring of Strokkur spouts steaming water 30 meters into the air every 8 minutes. Continue to one of Iceland’s most iconic features at the Gullfoss Waterfall (“Golden Falls“). Feel the spray of the waters of the glacial River Hvítá as it plummets down into a 32-meter deep crevice. Next, enter Þingvellir National Park, where the North American and Eurasian tectonic plates are pulling apart at a rate of a few centimeters per year. Þingvellir was named a UNESCO World Heritage Site for its cultural value in 2004, and is the site of a stunning rift valley and the Rock of Law, the first Viking parliament. Marvel at the volcanic crater at Lake Kerið, and pass through the Icelandic farms of the south on your drive around the Golden Circle, before returning to your original starting point in Reykjavik.

Have an out-of-this-world adventure while drysuit snorkeling in Silfra rift, a UNESCO World Heritage Site in Thingvellir National Park. The hidden natural wonder has 100 meters of underwater visibility with bright colors that make the experience almost unrealistic. Meet your guide and group directly at the site in Silfra and prepare to travel between two continents in the rift. Be guided through magnificent scenery and view Silfra from the surface while the slow current carries you through the stunning underwater landscape. Stay dry underneath your drysuit or, for the more adventurous, choose the wetsuit to feel the natural cool waters. Snorkel through the pure and clean waters of Silfra and end the tour in a lagoon often called "the real blue lagoon" because of the bright blue color of its water. 

Enjoy a snorkeling tour of the Silfra Fissure in Thingvellir National Park, a UNESCO World Heritage Site and one of the wonders of the famous Golden Circle route. Float between two tectonic plates in the clearest water in the world with 300 feet, or 100 meters, of visibility. Once you arrive at Silfra, you will be divided into groups of 6 people, one group per guide. Gear up in a wetsuit to keep you warm and comfortable in the cold water. After a safety briefing, make your way to the entry platform to spend about 45 minutes in the water. Float through what is called the Big Crack, Silfra’s narrowest section where the continental plates are so close you can almost touch them. The fissure then widens into Silfra Hall. If you look from the right angle, you can see all the way to lake Thingvallavatn, over 150 meters away.  Enter the Silfra Cathedral at the depth of 23 meters and feel like you’re flying over the boulders and glacial silt. End the snorkeling adventure at the Silfra Lagoon. Enjoy hot chocolate and cookies to warm up. Chat with your guide and ask any questions you might have.

Explore breathtaking ice formations and glacier mills on this guided tour in Skaftafell. Marvel at a naturally-formed, blue ice cave and learn how glaciers are formed. A professional hiking guide will take you to the base of Falljökull, an outlet glacier of the Vatnajökull ice cap, and lead you up to the cave. On a clear day, be sure to look out for Hvannadalshnúkur in the distance.

Embark on a bus tour of Iceland’s legendary Golden Circle and soak in the thermal waters of the Secret Lagoon. Explore the southwest, including the spectacular Geysir area, Gullfoss Waterfall, Kerið Volcano, and Þingvellir National Park. After pickup in central Reykjavik, the day's first stop is at the Kerið Volcanic Crater. Here you can circle the crater top along a winding path and descend into the crater to reach the lake at its center. Next, head to the Secret Lagoon where you'll have 1.5 hours to unwind in the thermal waters and admire the peaceful surroundings. Continue to the active hot spring of Strokkur and watch it spout steaming water 30 meters every 8 minutes. Arrive at Gullfoss Waterfall and feel the spray of the glacial Hvítá River as it plummets down into a 32-meter-deep crevice.

Þingvellir was named a UNESCO World Heritage Site in 2004.

Snorkel at a site that National Geographic called one of the top dive sites in the world with this tour of the Silfra Fissure in Þingvellir National Park. Stay warm as you explore this magical underwater glacial world with a high-quality dry suit. Swim through pure, filtered glacial meltwater. Keep your eyes peeled for local plant species and marine life like the dwarf char. Explore the valley where the tectonic plates of North America and Europe drift further apart every year, located in the UNESCO World Heritage Site of Þingvellir National Park.

Explore the dramatic landscapes of the south of Iceland on a full-day sightseeing tour by bus. Go to the Jökulsárlón Glacier Lagoon outlet of the largest glacier in Europe, leaning about its history and formation from your local guide. Following a pickup from your hotel in Reykjavik, transfer to the southern coast and the dramatic Glacier Lagoon. Enjoy plenty of time to see the floating icebergs and enjoy the stunning scenery. During the season, make sure to reserve your ticket to the boat cruise on the Jökulsárlón and experience the unique Glacier Lagoon spectacle up close. When you prebook, your place is guaranteed. Jökulsárlón Glacier Lagoon is Iceland’s largest and deepest glacier lagoon. It branches from Breidamerkurjokull, an outlet glacier of Vatnajokull, Europe’s largest glacier.

Admire views of Iceland's stunning landscape as you ride from Reykjavik to the heart of Thingvellir National Park, a UNESCO-listed World Heritage Site. Snorkel in this location for 45 min with your guide, before returning to the warmth of the tour van and heading back to Reykjavik. The cold waters melt off a glacier 50 km (30 miles) away and make their way through lava fields to beautiful Thingvellir Lake. Although the chilly waters are too cold to support much in the way of marine life, Iceland's Silfra crack runs down between the American and European continental plates and offers amazing underwater views.

Start the day with lunch and set off on a 4-hour hike through the sprawling lava fields of Laugahraun, Vondugil Canyon and up to the summit of the colorful mountain of Brennisteinsalda with its steaming vents and Sulphur deposits. Descend through the Grænagil canyon, carved as a result of geodynamic activity of mountains, volcanoes and glacial rivers. If time and weather conditions allow, climb Bláhnúkur, a circa 60,000-year-old volcano with panoramic views of the Landmannalaugar Valley.  Have a bath in a natural hot pool, where both hot and cold water flow out from beneath Laugahraun, mixing together and forming the perfect bathing conditions. Remember to take your swimwear and a towel with you.
