Silfra Wetsuit Snorkeling – Meet on Location | Free Photos

Silfra is one of Iceland’s strangest swimming spots: a water-filled crack in the ground with visibility that can exceed 100 metres. You float through clear glacial water in Thingvellir National Park, between the slowly separating North American and European continental plates.

I like the small groups of up to six and the free underwater photos, which let you enjoy the swim without worrying about a camera. I also like the careful guides, including Alex, Inigo, Kaja, Dory, Jane, and Fernando, who are praised for helping nervous participants feel safe. The main drawback is simple: this is cold-water snorkeling, and getting into a tight wetsuit or drysuit can be harder than expected.

Key points

• Visibility can exceed 100 metres: Silfra’s filtered glacial water gives you unusually clear views below the surface.
• You meet at the fissure: Park in P5 at Thingvellir and find the Adventure Vikings snorkel vans.
• Groups are limited to six: One guide handles each small group, with as many as three groups at the site.
• The water is about 2 C: A drysuit helps keep your body dry, but your hands and face still feel the cold.
• Photos and hot chocolate are included: Expect roughly 40 to 100 downloadable underwater photos, plus a warm drink afterward.
• Strict participation rules apply: You must know how to swim, communicate in English, and meet the height and weight limits.

Why Silfra feels unlike ordinary snorkeling

I usually think of snorkeling as a warm-weather activity, but Silfra is a very different proposition. The water comes from glacial melt that travels underground for about 50 kilometres before reaching the fissure. It is cold, exceptionally clean, and so clear that the rock formations below can look close enough to touch.

The water-filled rift sits in Thingvellir National Park, a UNESCO World Heritage Site. The park occupies a rift valley between the North American and European continental plates. The plates are moving apart by roughly 2 to 3 centimetres each year, though you should not expect to place one hand on each plate. They are separated by about 6 to 7 kilometres in this area.

That geological setting gives the experience its real value. You are not simply swimming in a scenic pool. You are moving through a visible part of the Earth’s ongoing geological change, with the fissure walls and clear water making the setting feel unusually direct.

Meeting at Thingvellir and getting ready

This is a meet-on-location activity, not a city pickup. You drive to Thingvellir National Park, park in P5, and walk to the area where the snorkel and activity vans are gathered. The exact meeting point is listed as Silfra Adventure Vikings, 7V4M+HG8, 806 Thingvellir, Iceland.

After you find your guide, the group receives an outline of the activity and the equipment process. You then change into your swim gear and the provided snorkeling equipment before listening to a safety briefing. Allow yourself enough time to arrive without rushing, since getting into the suit requires care.

The preparation is a real part of the experience. A drysuit must seal around your neck and wrists, and guides may adjust straps around the arms and ankles for a better fit. Several people find the suit tight, bulky, or awkward at first. That is normal, but it can be uncomfortable for anyone with claustrophobia or limited comfort in the water.

Wear a swimsuit underneath. For a drysuit, long thermal underwear and thick wool socks are recommended, and thick socks are especially useful for keeping your feet warmer. Bring a towel, a change of clothing, and weatherproof outer layers for the time before and after the swim. Jeans and heels are not suitable.

The snorkeling route through Silfra

Once the safety briefing is complete, you enter the water with your guide. The actual snorkeling portion lasts about 30 to 40 minutes, though the whole activity takes roughly three hours because of arrival, preparation, changing, instruction, and photography.

The route carries you through the main sections of Silfra. You float over clear blue-green water, between submerged rock walls, and through narrow areas of the fissure. The exceptional visibility is the star of the show. You can look down through the water and see far more than you normally would in a snorkel setting.

The water temperature is around 2 C, or 35 F. That sounds severe, and it is cold, but the proper suit makes a major difference. With a drysuit, most of your body stays dry and many people find the swim less uncomfortable than expected. Your hands and the exposed part of your face are usually where the cold makes itself known.

You should also understand how the suit changes the way you move. A drysuit keeps you buoyant at the surface, so you are mainly floating and looking downward rather than swimming beneath the water. One person with wetsuit experience preferred that option because a wetsuit allows more freedom to move downward. A drysuit is often the more comfortable choice for staying warm, but it can feel less natural in the water.

There is little current to worry about, and guides remain close to the group. Still, swimming in a constricting suit takes effort. If you are nervous, tell your guide early. Guides such as Alex, Dory, Inigo, Jane, Kaja, and Fernando are repeatedly praised for explaining the equipment, staying patient, and helping people who are unsure about entering the water.

What the cold really feels like

The cold is the main practical question, and the honest answer is that it depends on your clothing, the weather, and your tolerance. Several people stayed warm through most of the swim in drysuits, while hands, feet, and face caused more trouble. Winter weather can make the changing process after the swim feel colder than the time in the water.

Eat breakfast before you arrive. You will be using energy while getting suited up, swimming, and changing in Icelandic weather. Bring warm, close-fitting layers to wear beneath a drysuit, not just a swimsuit.

A wetsuit can offer a more flexible feel, but it places you in direct contact with cold water and may be a poor choice if you are sensitive to cold. The activity information allows for wetsuit or drysuit equipment, so check exactly which option you are booking. If you accidentally book one option, ask the operator about changing it, but do not assume a different suit will always be available.

After the swim, you get hot chocolate. It is a modest extra, but it is well timed. A warm drink gives you a pleasant finish while you gather your belongings and change back into dry clothing.

The guides and the value of a six-person group

The guide may matter more here than on an ordinary sightseeing stop. You need help with the suit, the mask, the entry into cold water, and the practical problem of moving while heavily padded and sealed. A calm guide can turn the first few minutes from intimidating to manageable.

The guides named in the feedback include Alex, Inigo, Kaja, Dory, Jane, and Fernando. Alex is praised for being attentive, friendly, and reassuring with families and teenagers. Inigo combines information about the area with a relaxed manner. Kaja helped make a winter outing feel manageable, while Jane was especially reassuring with an anxious participant.

Each guide handles a group of up to six people. That limit matters. You are not pushed through the water in a large crowd, and the guide can keep an eye on each person. Up to three separate groups may be present at the activity site, so this is not necessarily a private swim, but your own group remains small.

The group size also affects the pace. Guides can spend time explaining the surroundings and helping people adjust their breathing and position. If one person is uncomfortable, the group may move more slowly. That is a benefit for safety and confidence, though anyone seeking a fast, athletic swim may find the pace gentle.

Free photos make the outing easier

The guide takes underwater photos during the swim, with no extra commission charge. You normally receive about 40 to 100 images, depending on group size and how comfortable the group is in the water. The photos are downloadable after a few days.

I consider this a meaningful part of the price. You cannot easily take your own pictures while dealing with a mask, gloves, cold water, and a buoyant suit. Having a guide handle the photography means you can look around and stay focused on the experience.

The number of images is not fixed, so do not book this expecting a guaranteed photo package of a particular size. Group size and the amount of time people spend moving through the water affect the final selection. Still, the included photos give you a record of the unusual setting without adding another rental or fee.

Is the $140 price fair?

At $140 per person, this is not a cheap add-on. The price is easier to justify when you count what is included: a PADI Divemaster, instructor, or equivalent guide; snorkeling equipment; wetsuit or drysuit use; underwater photos; and hot chocolate.

You are also paying for the equipment handling and safety support. Silfra is not the place to arrive with casual beach gear and expect to manage everything alone. The guide checks participants, explains the equipment, and stays with a small group in very cold water.

The value depends on your priorities. If you want a major Iceland activity with a strong geological setting, included photos, and personal attention, the price is reasonable. If you dislike cold water, tight clothing, or structured group activities, the cost may feel high for a swim that lasts only 30 to 40 minutes.

You should also remember that food, a towel, swimwear, and clothing suitable for the weather are not included. Transportation from Reykjavik is not listed here either, so you need to arrange your own way to Thingvellir.

Who should book this experience

This suits confident swimmers who want something more unusual than a standard sightseeing stop. You must be comfortable in water and able to swim without assistance. The activity is offered in English, and all participants must be able to communicate in English.

The minimum age is 12. Anyone over 65 needs physician approval. You must be at least 150 centimetres tall and at least 50 kilograms, with maximum limits of 200 centimetres and 120 kilograms. You must provide age, height, and weight information to the operator, and you will complete a medical form before taking part.

Do not wear glasses in the mask. Bring contact lenses or your own prescription mask if needed. You should also check the medical statement before booking to confirm that you qualify.

I would be cautious about booking if you dislike enclosed clothing or have strong claustrophobia. Drysuits can feel tight around the neck and wrists, while wetsuits are close-fitting and expose you to more cold. The equipment is necessary, not decorative, so comfort with that trade-off matters.

Weather, cancellation, and planning details

The activity depends on suitable weather and a minimum number of participants. If poor weather causes a cancellation, you are offered another date or a full refund. The same applies if the minimum group size is not reached.

You can cancel for a full refund up to 24 hours before the start time. Within 24 hours, you do not receive a refund, and changes are not accepted. Cut-off times use local Icelandic time.

Plan this for a day when you can reach Thingvellir reliably and still have time to change afterward. The tour ends back at the meeting point. Since the swim itself is only part of the three-hour schedule, do not treat it as a quick stop between tightly timed activities.
