Embark on a one-of-a-kind snorkeling combo tour along the popular Golden Circle. The sightseeing route includes the fantastic Gullfoss Waterfall, Geysir Geothermal Area, and Þingvellir (Thingvellir) National Park, which houses Silfra Fissure.

Beneath Thingvallavatn Lake you'll explore the subaquatic oasis of Silfra, the only place in the world where you can swim between two continents. The Silfra snorkeling experience was voted as a top-five experience by Trip Advisor’s 2019 Travelers’ Choice and it's easy to see why! Follow up your underwater experience with the famous Golden Circle sights. Witness the explosive geyser Strokkur and the powerful cascade of Gullfoss Waterfall. This combo tour is the perfect day adventure!

The tour begins with a thrilling snorkeling adventure at Silfra Fissure. The fissure is located in Thingvellir National Park on a rift valley between the North American and Eurasian tectonic plates. Silfra was formed by a powerful earthquake in 1789, and the tectonic plates continue to drift apart at a yearly rate of about 0.79 in (2 cm). So when you go snorkeling you will actually be swimming between two continents!

To get to your Silfra snorkeling location you can either choose to be picked up from Reykjavik or meet us on-location at Thingvellir, where our friendly guides will be waiting for you.

Once you're onsite you'll be given all the necessary snorkeling gear and drysuit. Don't have any prior snorkeling experience? No worries. Our knowledgeable guides will walk you through everything you need to know. The only requirements are that you are able to swim, are in good health, and have an adventurous spirit.

For the tour, you'll swim in the "lazy current," a glacial water stream that flows calmly in the fissure. The crystal water has been filtered for decades by lava rock and is so pure you can drink it. Marvel at the vibrant blue and green water shades, orange seaweed, and spectacular rock formations. The water at Silfra boasts 100-meter (328 ft) visibility, so you'll have the perfect conditions for exploring the geological wonders below.

  • Silfra Big Crack is the narrowest and deepest section of the fissure at 394-ft (120 m) long and 147ft (45 m) deep. Along the passage are various caverns and swim-through holes.
  • Silfra Hall is where the fissure widens out and leads into a 26 ft (8 m) wide and 46 ft (14 m) deep area. The bottom of this 'hall' is covered with giant rocks, some half the size of a car!
  • Silfra Cathedral is 328-ft (100 m) long and 75-ft (23 m) deep. The area has such a strong current it almost feels like you are flying.
  • Silfra Lagoon is 16ft (5 m) deep and offers the best visibility. Here you’ll find the most dramatic views of the fissure floor and turquoise blue water.

After you dry off and change, enjoy a treat of hot cocoa and cookies.

Stunning Gullfoss Waterfall

At 12:00 pm we will end our underwater adventure and begin exploring the surrounding Thingvellir National Park. Thingvellir is Iceland's oldest national park and is listed as a UNESCO World Heritage Site for its historic and geological value. Besides the tectonic rift in its valley, it is where the world’s oldest parliament (the Alþingi)  was founded in 930 AD. The park limits contain dramatic landscapes, forests, and cliffs.

After Thingvellir, we’ll head to the Geysir hot spring area for a geothermal show. Witness the active Strokkur Geyser, which spouts scorching water every 8-10 minutes, followed by the now dormant Great Geysir. The impressive geyser eruptions are truly a feat of nature, shooting up to 130 ft (40 meters) in the air!

We finish up our Golden Circle experience with a stop at the thundering Gullfoss Waterfall, or “The Golden Waterfall. The attraction is the largest falls by volume in Europe, so you will hear it before you see it!

Gullfoss has an impressive two-tiered cascade with a 32-meter drop that plunges into a deep gorge below. Unlike most waterfalls, you view the cascade from the top, so it is an extraordinary sight to behold. The perfect end to your all-day adventure.

It is a magical experience. When snorkeling you will be wearing a dry suit, hood, and gloves made of neoprene, along with fins, mask, and snorkel. This equipment will make it not only possible but as well very enjoyable to stay in the water despite the cold temperature. Tripadvisor recently rated Snorkeling at Silfra as one of the Top 5 travel experiences in the world. 

No, you do not need any previous experience to snorkel, however, it is important that you can swim independently and feel comfortable in the water.

We provide you with high-quality neoprene dry suit so that your body stays dry. There is always a small risk that water can enter the dry suit, that is not dangerous but you can feel a little cold, therefore, we recommend you to bring an extra spare set of clothes and a towel, just in case. Note that your hands and face will get wet, which is completely normal.

You will be provided with high-quality neoprene dry suit from Waterproof International and O’Three. As well as neoprene hood and gloves to protect your head and hands from the cold. You’ll also be given fins, mask, and snorkel.

Yes, there are two toilet facilities at Silfra.

Occasionally fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back as they don’t like the cold glacier water. However, there is a lot of colorful seaweed including a bright green variety known as ‘’troll hair’’, which makes the fissure unlike anything on the surface.

Silfra can be up to 60m deep. However, when you’re diving in Silfra than you will go about 7 to 12m deep, and the maximum diving depth that is permitted is 18m.
