However, the air temperature and weather conditions may be more favorable during summer. Keep in mind that Silfra can be busier during peak season, so booking in advance is recommended.

Can I take underwater photos during a snorkeling tour in Iceland?

Yes, you can take underwater photos during your snorkeling tour in Iceland. If you have a waterproof camera or a waterproof case for your phone, you are free to capture the stunning underwater scenery.
Some of the tours include underwater photography as part of the experience or rent out GoPro cameras to participants for an additional fee, such as this drysuit snorkeling tour with underwater photos.

Do I need to know how to swim when snorkeling in Silfra?

Yes, all participants must know how to swim when snorkeling in Silfra. Though the drysuits are very buoyant, guests are required to exert themselves physically whilst on the tour and navigate through the water.

Is the water cold when snorkeling in Silfra?

The water in Silfra is a consistent 2-3°C (35-37°F), year-round. Because Silfra has a light current running through it, the fissure never freezes, not even during the winter.

Do you need to wear a drysuit when snorkeling in Silfra?

Most operators require you to wear a drysuit, although some will also let you snorkel in a wetsuit. There are no options to snorkel without protective equipment, however, as the water in Silfra is far too cold.

Are there any snorkeling tours in the ocean surrounding Iceland?

No, all snorkeling tours in Iceland take place in Silfra fissure at Thingvellir National Park.

Is the water drinkable in Silfra?

Yes, and delicious. Remember "The Golden Rule", however, and don't drink too much (drysuits are known for self-containing any liquid).

How long does my snorkeling tour at Silfra last?

The tour lasts at least two hours when snorkeling in Silfra fissure, with snorkeling time ranging between 30 and 45 minutes.

Is it possible to negotiate about the age limit for snorkeling in Silfra?

No, the tour operators need to adhere to Icelandic law, which states that you must be 14 years of age in order to take part in snorkeling in Iceland.

Is there fish in the Silfra fissure?

Compared to other snorkeling sites that are abundant with wildlife, the appeal of diving in Silfra is its crystal clear water, exploring geological formations, and the overall uniqueness of diving between tectonic plates. However, some small fish may reside there such as the diminutive Dwarf Char, but mostly they stay in the depth near the rocks so they are unlikely to be spotted by snorkelers.

What is the visibility like when snorkeling in Silfra Fissure?

Silfra Fissure is known for its exceptional underwater visibility, which can exceed 100 meters (328 feet) on a clear day. The crystal-clear water is a result of the slow filtration of meltwater from the nearby Langjokull glacier through the porous volcanic rock, which can take over 100 years to reach the ravine.

What other equipment will I use when snorkeling in Silfra?

Alongside the drysuit, you will wear a pair of neoprene gloves, a neoprene hood, a pair of fins, and a snorkeling mask when snorkeling in Silfra.

Will my snorkeling tour in Silfra be cancelled if it's raining or snowing?

No, tours at Silfra will go ahead unless extremely strong winds warrant a cancellation. If you have any questions regarding this, please contact the tour operator directly or email our team at

What should I wear for a snorkeling tour in Iceland?

Due to the cold water temperatures, the tour operator provides participants with a dry suit or a thick wetsuit, gloves, a hood, and snorkeling equipment (mask, snorkel, and fins). It is essential to wear warm, thin layers of clothing, such as thermal or fleece, under the dry suit, and bring a change of clothes and a towel for after the snorkeling experience.

Can I participate in a snorkeling tour if I wear glasses or contact lenses?

If you wear glasses, switching to contact lenses for your snorkeling tour is recommended, as glasses cannot be worn with the provided snorkeling masks. If you wear contact lenses, you can use them without any issues during your snorkeling experience.

How do I get to the Silfra Fissure for a snorkeling tour?

Many tour operators offer pick-up services from Reykjavik, which is approximately a 45-minute drive from Thingvellir National Park. Alternatively, you can rent a car in Iceland and drive to the Silfra Fissure yourself, but make sure to allow ample time for parking and finding the meeting point.

Due to the physical nature of snorkeling and the use of dry suits, participants must be in good health and able to swim. Certain medical conditions, such as heart or lung issues, may require clearance from a doctor, and pregnant women are not advised to participate in snorkeling tours.
Additionally, there are some age, height, and weight requirements that differ between tour operators, so be sure to read the tour description carefully before booking it.
