Silfra: Fissure Snorkeling Tour with Underwater Photos

Silfra feels like another planet under ice. You snorkel the Silfra Fissure in Þingvellir National Park, right where the tectonic plates of North America and Europe slowly drift apart, with a dry suit that lets you enjoy the water without getting wrecked by the cold.

I really like that the experience is built around safety and easy guidance, and you finish with free GoPro souvenir photos plus hot drinks and cookies. One consideration: the dry suit can feel tight, and those first minutes in the water are genuinely cold before your body settles in.

Key Points Before You Go

• Swim between continents in the Silfra Fissure at Þingvellir, a UNESCO World Heritage Site
• Crystal-clear glacier meltwater with striking color and a chance to spot life like dwarf char
• Dry suit snorkeling designed to keep you warm and floating
• Small groups (max 6) with hands-on, safety-first guiding
• Included GoPro photos so you don’t have to juggle a camera in gloves
• Þingvellir on foot with timed walking segments that break up the experience

Why Silfra in Þingvellir Feels So Strange (in a good way)

Silfra is one of those Iceland experiences that makes your brain pause. Above water, it can look calm and almost ordinary. Then you slip under the surface and realize you’re swimming in filtered glacier meltwater that sits in a gap created by shifting tectonic plates—North America on one side, Europe on the other.

The big charm is the contrast: wild Iceland nature all around you, but inside the fissure you get an underwater world that feels clean, sharp, and unreal. I like that this tour doesn’t treat the water as the only attraction. You also get time on foot in Þingvellir National Park, which helps connect the fissure to the wider geology and atmosphere of the area.

And you’re not just dropped in. You get a structured setup, a safety briefing, and guided snorkeling through the key points of the fissure with your guide at your side.

Price and Value: What $148 Includes (and what that means for you)

At $148 per person for about 3 hours, you’re paying for more than a quick splash. The included essentials are what make this feel like real value instead of a DIY cold-water gamble: a PADI-certified guide, the dry suit plus snorkeling equipment, hot drinks and cookies, and GoPro photos taken for you.

That matters because Silfra isn’t a place where you want to improvise. The water is crystal-clear, cold, and gear fit affects comfort fast. The dry suit reduces the struggle, but it still needs to be worn correctly, and you need to understand how to move in it.

Also, the photo plan is smart. You get souvenir photos without figuring out camera handling while wearing a suit, gloves, and a mask. If you’ve ever tried to take photos in cold water, you’ll appreciate that the tour handles that part.

Getting There and Meeting at Troll Expeditions Silfra

You meet at Troll Expeditions Silfra at the company parking lot inside Þingvellir National Park. If you’re driving, you park at P5 parking lot and then walk to the Tröll Snorkel meeting point.

This is one reason I like this tour style: it’s direct and localized. You’re already where you need to be, and you can focus on dressing in layers and staying warm before gear goes on.

One small practical note: parking fees are not included. So if you’re budgeting tightly, plan for that extra line item.

The 30-Minute Safety Briefing and 3-Stage Setup

Your tour timing is built around getting you comfortable before the water part. The schedule starts with a safety briefing (30 minutes) right at the Silfra start point. Then you head out on foot for another 30 minutes, which functions like a transition and warm-up period—time to get your bearings, move a bit, and settle your gear routines.

After that, you get the guided snorkeling portion (50 minutes). Then there’s more on-foot time (30 minutes) before you return, followed by a break/free time window (30 minutes) before you head back to Troll Expeditions Silfra.

Why this pacing works: when you’re wearing a dry suit, your body has to adjust to new movement and fit. Doing the briefing and the walking segments first helps you avoid feeling rushed when you’re about to enter the water.

Dry Suit Snorkeling: Comfort, Cold, and the Actual Reality

Let’s talk about the part you can’t guess from photos: the dry suit experience. You’ll wear high-quality dry suit snorkeling gear with layers underneath. The suit is sometimes tight and constricting. You’ll be glad for the insulation later, but early on, it can feel awkward while you’re walking to the water.

The cold factor is also real, especially at the start. In multiple accounts, people report that the first minutes can feel extremely cold and numb areas like lips and forehead. The good news is that many say it eases after a couple of minutes once your breathing and movement settle and the suit does its job.

Another reassuring detail: the suit helps you stay buoyant. That means you’re not fighting to sink, which makes the experience feel less stressful—especially if you’re new to snorkeling.

Important limits are also part of the safety picture. This isn’t for everyone, including pregnant women. You also need to be physically fit and able to swim, and you must communicate in English. There are weight and height ranges too, plus an age limit (max 69).

Swimming Between North America and Europe (What You’ll See Underwater)

The heart of the tour is the guided snorkeling across the Silfra Fissure. You swim through filtered crystal-clear glacial meltwater with your guide, focusing on key points of the fissure where the tectonic plates continue to drift apart every year.

This is where the water’s look becomes its own event. People consistently describe the colors as astonishing. Even though it’s glacier meltwater, it doesn’t look gray or dull. It has bright, shifting tones you can actually feel with your eyes as you move.

You’ll also be encouraged to look for local life, including dwarf char. You may spot small movements or unusual shapes that look like they don’t belong in such icy water. When visibility is this good, even small underwater details start to feel like a highlight.

And yes, you’re beneath rocks and in a space that can feel deep. The experience can be a little intense for your sense of scale. That’s why the guide staying close matters. You’re given instructions for how to move, when to pause, and how to breathe calmly—so the cold and the depth don’t turn into panic.

On-Foot Segments in Þingvellir: More Than Waiting Around

It’s easy to think this tour is only the underwater part. It isn’t. You have on-foot time twice: once before the main snorkeling block and again after it.

Those walking segments help you do two useful things:

• get your body warm in layers before entering the water
• absorb the setting while you’re not dealing with mask, snorkel, and gloves

Þingvellir National Park is the backdrop for the fissure, so those extra minutes on land connect the geology to the place. You also get a break/free time window at the end, which can be helpful if you want to slow down and take in the area once you’re done.

In one example, a guest mentioned walking up to a frozen waterfall after the tour ended. If conditions are right and you feel up to it, that kind of add-on can be a nice way to extend the day without needing a separate tour.

Guides and Small Group Size: Why Max 6 Matters

This tour caps the group at 6 participants. I like small groups because it’s easier for guides to adjust to different comfort levels in the suit and in the water. It also tends to produce calmer instruction—less waiting, more attention.

The guide quality seems to be a core strength. Names that come up often include Anna, Kevin, James, Joaquin, Abby, Lillian, Vlad, Cecilia, and Mike. Across these accounts, the pattern is consistent: clear instructions, lots of reassurance, and strong safety focus.

One detail I really appreciate: warmed help. For people who get cold easily, a guide making the effort with warmed-up gloves (or bringing warmth options from the car) can be the difference between tolerating the first minutes and dreading them.

Also, changing clothes can be miserable in Iceland weather. One strong note: this company offers a heated truck to change in. That’s not flashy, but it’s practical and makes the whole start-to-finish feel smoother.

Hot Drinks, Cookies, and Your Free GoPro Photos

After you snorkel, you return, break, and then enjoy hot drinks and cookies. It’s a simple finish, but it’s exactly what you want after cold water. You warm your hands, reset your breathing, and stop feeling like you’re still clinging to gear.

Then comes the souvenir piece: GoPro photos included in the tour. That’s a big deal for an experience like Silfra where your hands and attention are busy. Having photos taken of each person, plus shots of the surroundings, means you don’t have to trade the moment for documentation.

A nice bonus of the photo setup is that it lets you focus on the experience while you’re in the water. You can look around, follow the guide, and not worry about dropping a phone or fumbling a camera in gloves.

What to Bring (and What to Leave at Home)

Iceland is a layering game. This tour asks you to dress for warmth and wind, because your comfort starts on land long before you hit the water.

Bring:

• warm base layer clothing (example: socks, leggings, shirt)
• change of clothes (just in case)
• contact lenses if you wear glasses

Leave behind anything that can snag or cause issues:

• no jewelry like earrings, bracelets, or watches

Also bring the medical statement required for participation. If you’re 60 or older, you’ll need medical clearance from a doctor (and the maximum age to take part is 69).

And don’t skip the practical part: plan to wear warm layers under the suit. The dry suit is the main barrier against cold, but your base layer helps you feel human when you’re walking to and from the fissure.

Who This Tour Suits Best (and Who Should Skip It)

This is a great fit if you:

• can swim and feel comfortable in cold water
• want a guided, safety-first snorkeling experience (not a solo experiment)
• like geology and want the tectonic plates story to be more than trivia
• appreciate included photos instead of managing your own camera

It’s not suitable for:

• pregnant women
• wheelchair users
• people under 135 cm or over 200 cm tall
• people over 70 years
• anyone who can’t meet the physical fit and communication requirements

If you’re new to snorkeling, you may still be a good match, as long as you follow instructions and you’re comfortable with the suit and mask process. The guide support is a major part of why people say they felt safe and relaxed.

If you have cold sensitivity concerns, consider that many guests report the first minutes are the toughest but improve quickly with proper gear and guidance. The warmed glove idea and heated changing setup are especially relevant here.

Should You Book This Silfra Snorkeling Tour with Troll .is?

Yes, you should book it if you want one of the most conceptually unique activities in Iceland: snorkeling between two continents in a UNESCO site, with gear that makes the cold manageable and photos included so you can actually remember the moment.

I’d think twice only if you know dry suits feel claustrophobic, you hate tight gear, or you’re not confident with swimming in cold conditions. Also double-check the age and medical requirements before you get excited.

If you’re physically able, comfortable in the water, and excited by geology plus clear-glacier wonder, this tour looks like strong value at $148—and it’s the kind of experience that tends to become the trip story you keep retelling.
