Snorkeling in North Iceland feels like stepping into two sci-fi worlds. This half day pairs Nesgjá fissure with its icy-clear, Silfra-like visibility and Litlaá river with the famous bubbling sands effect. I love the clear focus on comfort and safety, plus the small group size that makes the whole outing feel personal. One thing to consider is that the dry suit can feel tight, so you should plan on a little mental adjustment.

You’ll get a full briefing, then gear up in top snorkeling dry suits and slip into water that ranges from shallow and crystal-clear at Nesgjá to colder spring upwellings at Litlaá. The best part is that you’re not just seeing two spots, you’re comparing two completely different ecosystems in one day. If you hate cold, you’ll still be fine, but it helps to be the kind of person who can enjoy a chill challenge.

Max group size is small, the guide is a PADI instructor, and the gear is included. That combo matters because it keeps the experience smooth and helps you focus on the underwater details, not logistics.

Key things that make this double snorkeling stand out

• Two stops, 15 minutes apart, so you get variety without losing the day to long transfers
• Nesgjá fissure visibility that can exceed 100 meters when your snorkeling mask fits well
• Nesgjá wildlife chance, including arctic charr sightings in the fissure
• Litlaá bubbling sands, created by cold water erupting from the bottom in a warmer river environment
• Warm-up time with hot cocoa and cookies, so you don’t leave the water straight to the cold air
• Small group size (up to 4) with a guide who stays close and talks you through what you’re seeing

Nesgjá fissure: the North version of Silfra clarity

Nesgjá fissure is a freshwater fissure with water so clear it’s often compared to Silfra in Iceland’s south. Even though the snorkel area is quite shallow, it’s the kind of shallow where you can look forever, because the water clarity can be extreme. You can also see well beyond 100 meters, as long as your snorkeling mask does its job.

Here’s what I like: the tour doesn’t treat Nesgjá as a quick stop. You enter at the designated entry point, then snorkel down the fissure and into the lagoon area for about 30 to 45 minutes. That’s long enough to get oriented, watch how the bottom and rock textures change as you drift, and actually enjoy the place rather than rush through it.

One practical note is that visibility is influenced by the quality of your mask fit. That means when the guide helps you with gear, pay attention. A small adjustment can make a big difference between “I can see stuff” and “I can track details far away.”

You might also spot fish. The tour highlights a chance to see arctic charr, a type of salmon family fish that can live in the fissure. You’re not promised sightings, but it’s one of those extras that makes Nesgjá feel alive rather than purely scenic.

The short walk and warm cocoa reset

After your Nesgjá snorkeling session, you exit at the area provided and walk back to the parking lot. This is not just a “get out and go” moment. The tour builds in a warm-up with hot cocoa and cookies, which matters because you’ll likely be damp, chilly, and ready for a reset.

This break also gives you time to dry your focus. When you step out of extreme clarity water, your eyes need a minute. Warm drinks and a snack help you recover so you can enjoy the next stop instead of feeling drained.

Because the total day is about six hours, the rhythm matters. This pacing is designed so you’re not stuck in cold air for long stretches.

Litlaá river: bubbling sands in about 20°C water

Then comes the second snorkeling adventure at Litlaá river, and it feels like a totally different planet. The water here is described around 20°C, which is warm enough for snorkeling comfort in a dry suit context. But the real show comes from what’s happening beneath the surface.

Cold water erupting from the bottom creates the visual patterns often described as bubbling sands. You may see those swirling, textured shapes that look almost mechanical. It’s not just a neat effect, it’s a hint that the river has a constantly changing mix of temperatures and materials.

And that temperature mix supports life and color. The tour notes strange green algae, plants, multicolored sediments, and what sounds like a never-ending number of snails. If you like “micro surprises,” Litlaá is the stop that scratches that itch.

The tour also includes a gentle river float at the end. That matters if you’re a first-timer or if you want a low-effort finish. It’s a simple way to cap a day that’s already physically and mentally intense because you’re wearing gear and paying close attention underwater.

Gear and dry suit comfort: what you should plan for

This experience includes all snorkeling equipment, including a dry suit and a warm undersuit, plus the guide who helps you through the process. The dry suit means you’re not just relying on luck for comfort. The operator also asks for your height, weight, and age after booking so they can bring a dry suit that fits.

That’s a big deal for two reasons. First, a good fit helps warmth. Second, it helps you move and breathe comfortably. The tour also notes the dry suit can sometimes feel tight and constricting, so if you’re claustrophobic or sensitive to pressure, you’ll want to think about that before you book.

For the base layer, they specifically recommend long thermal underwear and thick wool socks under the dry suit. I agree with the logic here. Wool socks in Iceland are not a joke. They help you stay comfortable once you’re geared up and then again after you step out.

Minimum and maximum body sizes also apply. You need at least 150 cm height and 45 kg weight, and there’s a maximum of 200 cm height and 120 kg. The tour also requires that you’re comfortable in water and able to swim.

The guide factor: why the experience feels calm

A big part of your value is the human piece. This tour runs with a live guide who is a PADI instructor. In practice, that tends to mean you get clear instructions, a calm presence in the water, and help spotting what matters.

In the experience stories, the name that comes up again and again is Arnar. The way he’s described is consistent: he explains things beforehand, stays helpful throughout, and points out interesting underwater details while keeping things relaxed. There’s also a mention that he makes it easier to handle the gear and get comfortable, including helping with photos so you leave with more than just memories in your head.

For you, this matters because snorkeling in cold, high-clarity water can feel different from swimming in a pool. A confident guide helps you focus on what you’re seeing instead of second-guessing your body position, breathing, or timing.

Timing, pace, and group size for a better day

The meeting point is Skúlagarður Country Hotel & Restaurant in Ásbyrgi, and the start time is 10:00 am. The tour ends back at the same meeting point, and the total duration is about 6 hours.

The group size is kept small, with a maximum of 4 travelers. That’s not just a comfort perk, it also helps with gear fitting and attention in the water. When you’re in a dry suit, especially if you’re new, the difference between “everyone figure it out” and “the guide stays close” is huge.

As for physical demands, the tour says you should have moderate physical fitness. You also need to fill out a medical form before participating. If you’re over 60, the tour notes that you must have your doctor sign the approval form.

There’s an age minimum too: you must be at least 12 years old. Everyone needs to be able to communicate in English.

What the day feels like, step by step

Here’s the flow you should expect, and why it works.

First, you arrive, meet the guide, and get a detailed briefing. Then you get dressed into the snorkeling dry suit and other gear, which is one of the most important parts because comfort affects how well you enjoy the water.

At Nesgjá fissure, you enter at the entry point and snorkel for about 30 to 45 minutes. You’ll then exit and walk back to the parking lot, where you get a warm-up with hot cocoa and cookies.

Next you move to Litlaá river. You go through the gear routine again and snorkel where the conditions and visuals are completely different. The mix of warm-ish river water and cold upwellings creates the bubbling sands effect and a surprisingly colorful ecosystem, including algae, sediments, and snails.

After the second snorkeling session, you have an opportunity to buy photos from the tour and chat with your guide about the area. Then it’s time to remove gear and continue your day.

Value check: is $274 per person worth it?

At $274 per person for about six hours, you’re paying for three things that are hard to replicate on your own: expert supervision, high-end dry suit snorkeling gear, and two guided snorkeling locations in one outing.

If you were to DIY, you’d have to solve all three problems: where to go, how to gear up safely in cold water, and how to understand what you’re looking at once you’re there. This tour handles that for you, including a briefing and a guide who stays attentive. The small group size also adds real value, because it improves the experience quality even if the itinerary looks simple on paper.

If you’re the kind of traveler who likes comparisons, this combo is especially good. You get Nesgjá’s clean fissure world, then Litlaá’s bubbling sands world, back-to-back, with the same type of gear and expert guidance.

Who should book this tour

This is a strong match for you if:

• You want two North Iceland snorkeling environments in one day
• You’re okay with a dry suit and can follow safety instructions
• You like guided explanations and underwater spotting, not just drifting around
• You’re comfortable in water and can swim

It’s also a good fit if you’re doing a North Iceland road trip. The two snorkeling spots are described as about 15 minutes apart, so it can slot nicely into a self-drive day plan.

Who should skip (or at least think twice)

Skip or pause before booking if:

• You feel strongly uncomfortable in tight or constricting gear, because the dry suit can feel that way
• You cannot complete the medical form process, or you do not have doctor approval if you’re over 60
• You’re not comfortable swimming or you’re not able to communicate in English during the tour

The tour is not for “I’ll figure it out in the water” types. It’s best when you come prepared to listen, gear up correctly, and enjoy the process.

Should you book? My practical call

If your goal is authentic, guided snorkeling with real variation, I’d book this. The value is strongest in the pairing: Nesgjá fissure gives you Iceland’s famous kind of clarity, while Litlaá bubbling sands gives you the kind of underwater patterns you rarely see anywhere else. Add in the small group, the PADI instructor guidance, and the warm cocoa reset, and you get a day that feels thoughtfully put together.

If you want a relaxed swim with no instruction, this might feel a bit structured. But if you want the best chance to see what’s actually going on underwater, this tour is built for that.
