You do not need to be an experienced diver to experience Silfra. Every year, thousands of first-timers slip beneath the surface of this glacial fissure and come up transformed. If you are planning your first visit, here is everything you need to know before you arrive.

First, decide on your experience type. Snorkelling requires no prior experience and is the most accessible way to see Silfra. Freediving tours are suitable for anyone comfortable in water and able to hold their breath for a few seconds — your guide will coach you through basic technique. Scuba diving requires an Open Water certification or higher and also a drysuit certification.

Arrive at Þingvellir National Park with time to spare. Your guide will meet you at the Silfra car park (you can park at P5 car park) and brief the group before you suit up. The changing process takes around 20–30 minutes. Wetsuits are fitted on-site and your guide will check everything is secure before you enter the water.

The water entry is a short walk from the changing area. The cold on your face is the first thing you will notice — it is sharp and clarifying, like nothing else. Within a minute, you will forget about the temperature entirely and start absorbing the views. The water is so clear it looks almost unreal, more like flying than swimming.

The tour typically lasts around two and a half hours including briefing, suiting up, the dive itself, and changing back. Warm drinks after the dive are very welcome. Dress normally and remember to take a towel and swimsuit with you for the wetsuit. Silfra is unforgettable. The only mistake is not booking it.

When you think of diving into the 2–4°C (35–39°F) glacial waters of the Silfra Fissure, your first instinct might be to reach for the thickest drysuit possible. But at Freedive Iceland, we believe that to truly connect with this geological wonder, you need more than just warmth—you need total freedom. While drysuits are the “standard” for tourists, they often act like a bulky life jacket, keeping you pinned to the surface. To experience Silfra in 3D, our expert-led freediving tours prioritize specialized open-cell wetsuits.

The “Dry” Secret of Open-Cell Neoprene

A common myth is that choosing a wetsuit means spending your entire dive soaked in freezing water. However, the high-quality 7mm open-cell freediving suits we provide at Freedive Iceland work differently than standard scuba or surfing wetsuits.

The term “open-cell” refers to the interior of the suit, which lacks a fabric lining. Instead, the raw neoprene creates a suction-cup effect against your skin. When properly fitted with a specialized lubricant, this seal is so tight that water mostly does not get into the suit. By eliminating the “flush” of cold water that happens in cheaper suits, you stay remarkably warm while remaining unburdened by the trapped air of a drysuit.

Stay Longer, Explore Deeper

One of the most surprising benefits of our wetsuit approach is the duration of the experience. Many visitors find that in a drysuit, they become cold faster due to inactivity; because they are just floating on the surface, their circulation slows down.

At Freedive Iceland, we find that our guests often stay in the water longer with wetsuits than in drysuits. Because the specialized freediving gear allows for maximum mobility, you are constantly moving, swimming, and duck-diving into the “Silfra Cathedral”. This active movement generates body heat, which is then trapped by the open-cell neoprene. Instead of a 30-minute surface float, you can enjoy a full, immersive session exploring the 100-meter visibility from every angle.

Why Settle for Floating?

Silfra is one of the top dive sites in the world, situated in the heart of Þingvellir National Park. Its visibility is so legendary that it often feels like flying rather than swimming. When you wear a drysuit, that “flight” is limited to a bird’s-eye view from the top.

By choosing Freedive Iceland, you are choosing an adventure that lets you:

• Glide between the North American and Eurasian tectonic plates without the bulk of a “balloon” suit.
• Dive deep to see the vibrant “troll hair” algae up close.
• Move with the grace of a marine mammal, thanks to the superior flexibility of freediving-specific neoprene.

Whether you are an experienced freediver or a curious beginner, our private tours ensure a personal, safe, and exhilarating experience. Don’t just see Silfra—become a part of it. Experience the rift as it was meant to be seen: unrestricted, deep, and unforgettable.
