Compare snorkeling tours in Iceland to explore clear, cold water and unusual underwater landscapes. Tours operate year-round, including winter, although participants must meet the operator’s age, swimming ability, health, and size requirements.
Snorkeling in Iceland offers a different experience from snorkeling in tropical waters. Most tours use drysuits, with wetsuit options also available, as you float through rocky fissures instead of swimming above coral reefs.
Water activities rank sixth among Iceland’s most underrated experiences in a 2026 survey of tourism professionals. Snorkeling also ranks among the three highest-rated activities in a separate study of 1,309 Icelandic day tours. It’s also one of the most reliable tours, as our study of the best snorkeling companies in Iceland found only about 1.1% of Silfra tours are called off.
To add local insight, we spoke to Grétar Þorláksson, an experienced guide for a top-rated Silfra snorkeling tour from Reykjavik. He explains what first-timers can expect, how drysuit and wetsuit tours differ, and what visitors enjoy about the underwater experience.
The snorkeling tours listed here center on Silfra Fissure in Thingvellir National Park. Choose a meet-on-location experience, a tour with Reykjavik transfers, or a combination trip with other activities.
These three Silfra snorkeling tours offer different ways to fit the experience into your trip. Compare their meeting points, transportation, and included activities before choosing.
Silfra Snorkeling Tour Between Two Continents With Photos and Snacks: Meet your guide at Silfra for a snorkeling tour with equipment, underwater photos, and refreshments included.
Snorkeling in Silfra From Reykjavik With Underwater Photos: Choose a drysuit snorkeling tour with round-trip transportation from Reykjavik and underwater photos included.
Golden Circle and Silfra Snorkeling With Underwater Photos: Combine Silfra snorkeling with Golden Circle sightseeing on a day tour from Reykjavik.
Silfra snorkeling tours take place in Thingvellir National Park, within the rift valley between the North American and Eurasian tectonic plates. Its exceptionally clear water lets you see deep into the fissure while floating at the surface.
The underwater view is one of the main reasons to choose a Silfra tour. Grétar notes that visitors are often surprised that the water looks just as clear in person as it does in photographs, without filters or editing.
“Don't expect wildlife. Instead, expect incredible rock formations, freshwater algae, and a completely different underwater landscape.”
— Grétar Þorláksson, Silfra Snorkeling Guide
The gentle current helps carry you through the fissure, giving you time to take in the surroundings. Grétar describes the experience as almost a mindfulness session, with snorkelers floating along and enjoying the view at an unhurried pace.
Silfra snorkeling tours offer drysuit and wetsuit options to help protect you in the cold water. Your choice of suit affects how you feel and move during the tour.
Drysuits keep your body dry and provide buoyancy at the surface, while layers underneath help keep you warm. Wetsuits allow water inside and help retain body heat, with more freedom to move.
“For people who are claustrophobic or really dislike the constrictive feeling of a drysuit, a wetsuit can be a good alternative. For confident swimmers in wetsuits, there is also the option of duck-diving below the surface.”
— Grétar Þorláksson, Silfra Snorkeling Guide
Beyond equipment, compare shared and private tours, transport options, and included activities. You can book snorkeling on its own or combine it with other experiences.
Shared tours let you join other travelers, while private tours let you book the experience for your own group. You can book snorkeling on its own or choose a combination tour with Golden Circle sightseeing, lava caving, or horseback riding with Silfra snorkeling.
Check each listing for underwater photos, refreshments, transfers, and other inclusions. Snorkeling equipment is provided, but the clothing you need to bring depends on the suit and operator.
Silfra snorkeling tours follow Thingvellir National Park’s safety rules, including suitable cold-water equipment and medical screening. First-time snorkelers are welcome, but participants must be able to swim, feel comfortable in the water, and communicate with their guide.
Most tours have a minimum age of 12, along with height and weight limits to ensure the equipment fits properly. Exact limits and rules for accompanying minors can vary, so check your chosen tour before booking.
Participants must complete a medical screening form and obtain a physician’s approval if required. Review the form’s instructions before your visit so any medical clearance can be arranged in advance.
Your guide helps you put on the drysuit and checks its fit before you enter the water. Getting everyone properly equipped takes time, so preparation is an important part of the tour.
“I always tell first-timers that the anticipation is often more intimidating than the snorkeling itself. Once they put their face in the water, they usually forget about the cold pretty quickly.”
— Grétar Þorláksson, Silfra Snorkeling Guide
You receive a briefing before entering the fissure, and your guide accompanies the group in the water. Grétar notes that the first few minutes can take some adjustment as you get used to floating and moving in the buoyant suit.

A meet-on-location drysuit snorkeling tour suits travelers who are on self-drive tours or plan to drive the Golden Circle independently. You can rent a car from Reykjavik and book a tour that starts at Silfra.
For those who prefer not to drive, several tours include transportation from Reykjavik, including wetsuit snorkeling with Reykjavik transfers. Pickup locations vary by tour.
Pickup may be available at selected accommodations in Reykjavik or designated tour meeting points. Check your chosen listing for the pickup location and time.
If you are staying at one of the Golden Circle hotels, a meet-on-location tour may fit your itinerary. You can travel directly to Silfra and continue exploring the area afterward.
Compare the total duration when choosing between these options. Tours with transfers include travel time, while meet-on-location tours give you more flexibility to plan the rest of your day.
