Snorkel in the crystal-clear glacial waters of the Silfra fissure in Thingvellir National Park on this 4-hour experience from Reykjavik. Don the supplied snorkeling gear and swim between the continental plates submerged in the fissure. Admire the multicolored rocks and water clarity, and follow your guide to swim around Silfra’s highlights. Post-snorkel hot chocolate, cookies and entrance fees are included.
What to Expect
Your snorkeling destination is Silfra, an underwater ravine near Lake Thingvallavtan, located inside UNESCO-listed Thingvellir.

This freshwater gorge is formed from a crack in the Earth’s crust where the world's continental Eurasian and North American tectonic plates lie a short distance apart. The ravine water is estimated to be 1,000-year-old glacial water from Iceland’s second-biggest glacier, Langjökull, and takes about 30 years to filter through the lava rock, making it incredibly clear.

On arrival at Silfra, change into the provided warm undergarment and drysuit. Next, don the supplied face mask, snorkel, and fins, and listen to a comprehensive safety briefing and instructions. Then, with a guide showing the way, descend into the crystal-clear waters for a 30- to 40-minute expedition.

Admire the electric blues of the water and multicolored rock formations, and follow your guide through the four main areas. Swim through the Silfra Big Crack where the continental plates almost touch each other, and soak in the majesty of Silfra Cathedral, Hall, and Lagoon. The water clarity is such that visibility can extend to 328 to 492 feet (100 to 150 meters). Your guide will take photos on route that will be available for downloading free of charge after your tour.

When it’s time, leave the water, change back into your everyday clothes, and savor hot chocolate and cookies. Your tour then concludes either when you leave Silfra independently, or enjoy a return transfer and drop-off at the original start point in Reykjavik.

INCREDIBLE once-in-a-lifetime experience!

First--Ivan was an amazing guide. He was funny and friendly and made the whole process very easy. Second, I'll give the bad news first: for the duration of the actual snorkeling, you will most likely not be able to feel your lips, face, or hands...More

Must Do!

Stunning to be in the crystal clear water. Easy to find and meet at the park so no need to book the tour from Reykjavik. Your hands will be freezing cold, but worth the discomfort. Getting the gear on takes the longest. Actual time in...More

Do it ...

For the 60-somethings out there ... Snorkeling at Silfra was definitely me stepping outside my comfort zone ... and it was fabulous. The guide (Iceland Adventure Tours) was patient, kind and thorough. Exhilarating activity in October ... but the equipment provided makes it doable. Very...More

This has to be one of my top-10 life experiences. Yeah, it is a little difficult putting on the gear but Manuel was great and he'll get you in it. (By the way, Manuel was great - very knowledgeable and personable.) Make sure you use...More

You will need to get a ride to the car park. I recommend you do because there is so much to do around the park. Nice walking trails and a beautiful waterfall within walking distance from each other.

I don’t know what a snorkel vest is but you won’t need anything else. The suit they provide floats.
