Title: Silfra Just Levelled Up: Dive.is Now Offers the Whole Collection

The water in Silfra is so clear that you can see roughly 100 meters ahead of you. The choice of how to experience it just got a lot clearer, too.

I have been sending readers to Dive.is for years, because floating between two continents in the clearest water on Earth is one of those rare things that actually lives up to the hype. And it is official now: in the 2026 Tripadvisor Best of the Best Travelers’ Choice Awards, the Silfra snorkeling tour was named the number one “Once in a Lifetime” experience in the entire world. Not the best in Iceland. The best, full stop. (Even the Icelandic press took notice.)

So here is the good news for you, my fellow Iceland-planner: Dive.is no longer offering just the one tour. They have rolled out the full collection — snorkeling and diving, self-drive and with pick-up, small private groups, and even a second dive site most visitors never hear about. Let me walk you through it like I would a niece who just told me she is coming to Iceland and wants to do “the thing with the two continents.”

First, why Silfra is worth the cold

Silfra is a fissure in Þingvellir National Park where the North American and Eurasian tectonic plates are slowly pulling apart. It fills with glacial meltwater that has spent decades filtering through porous lava rock, which is why visibility exceeds 100 meters and the water is clean enough to drink mid-snorkel. (Go ahead and take a sip. You will not get the chance often.) It sits right on the Golden Circle, so it slots neatly into a day you are probably half-planning already.

The water is a steady 2–4°C year-round, but do not let that scare you off — you are sealed inside a dry suit with thermal layers, and Dive.is. It warms you up afterward with hot chocolate and cookies. Their guides are all trained PADI divemasters and instructors, and they built their own heated changing van so you are not wrestling into neoprene in a car park.

The snorkeling tours — for (almost) everyone

No diving certificate needed here. If you are at least 12 years old, can swim, and are reasonably fit, you can do this. There are three flavors:

• Silfra Snorkeling Day Tour (meet on location) — the award-winner itself, and the best value. You drive yourself to Silfra and meet the guides there. Prices start from around 17,990 ISK. Perfect if you already have a rental car for the Golden Circle.
• Silfra Snorkeling Tour with pick-up from Reykjavík — their most popular option. No car, no problem: they collect you in town and the one-hour drive doubles as a little geology lecture. Reckon on 5–6 hours door to door.
• Family & Friends Snorkeling Silfra Tour — a private small-group tour (max 6) just for your own people. Lovely if you are traveling with kids or want a more relaxed, personal pace without strangers in your group.

The diving tours — for certified divers

If you are a certified diver, this is where it gets special. To join a dive tour, you will need to be PADI Open Water (or equivalent) and have a dry-suit certification or logged recent dry-suit dives. The line-up:

• Silfra Diving Day Tour — the classic dive, meet on location.
• Silfra Diving Tour with pick-up from Reykjavík — same dive, with transport sorted.
• Silfra Diving Buddy Tour — for experienced pairs who want to dive together with more independence.
• Davíðsgjá Dive Tour — the hidden gem. A quieter lava-formation dive site by Lake Þingvallavatn that most visitors never see. If you have already done Silfra, this is your “next level.”
• Silfra & Davíðsgjá Diving Combo — both dive sites in one day. The full Þingvellir underwater experience for serious divers.

 Practical tips for your Silfra experience

• Self-drive or pick-up? If you have a rental car, self-driving is cheaper and lets you linger in Þingvellir afterward. No car? The pick-up tours are worth every króna for the convenience and the guide’s commentary on the way.
• Dress smart underneath. Bring proper long thermal underwear and thick wool socks — that is what actually keeps you warm, not the suit alone. Arrive already wearing your base layer to skip the changing-van queue.
• Book a morning or late slot in summer. Silfra gets busy at midday in high season, and there can be a short wait at the entry platform. Earlier or later is calmer.
• Wear contact lenses if you normally wear glasses — they will not fit under the mask.
• Buy the photo package. You cannot easily take your own camera in, and trust me, you will want proof you floated between continents.

Whether you are a first-timer who just wants to float in that impossibly blue water, or a diver chasing both Silfra and Davíðsgjá in a single day, there is now a Dive.Is the tour cut to fit you? Sign up, claim your code, and go see why the world voted it number one.

See you between the continents.
