About Snorkeling Tours

Snorkeling tours in Iceland are conducted in Silfra fissure, found within Þingvellir National Park. Silfra is a natural glacial spring, boasting water visibility that exceeds 100 m (330 ft). If you wish to partake in a tour here, you must wear a drysuit or wetsuit to stay comfortable in the 2-3°C water. Only those who can swim are permitted on snorkeling tours.

1. Can I meet the guides on the location?

Yes, though the specific meeting point will differ with each operator. Some may wish to meet you at the nearby visitor's centre, others in Silfra car park. Contact your tour operator directly, or alternatively, email for further information.

2. Do I need to know how to swim?

Yes, all participants must know how to swim. Though the drysuits are very buoyant, guest are required to exert some physical exercise whilst on the tour.

No, the tour operators need to adhere to Icelandic laws.

4. Is the water cold?

5. Do you need to wear a drysuit?

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 is far too cold.

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

8. Are there snorkeling tours in the ocean?

No, all snorkeling is done in Silfra fissure.

9. Is the water drinkable in Silfra?

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

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