Silfra Fissure probably has the clearest water in the world. That‘s mainly because of the cold temperature and lava filtration. It‘s always cold, from 2°C – 4°C. The source is glacial water from Langjokull and on its travel It has to break through lava, so it gets filtrated on its way.

Lava Caving in Iceland

The day’s adventures begin when we pick you up from Reykjavik. Our first activity is exploring Raufarhólshellir Lava Cave, one of the most popular lava tubes in Iceland. We’ll trek deep into one of the longest lava tunnels in the country at a whopping 4461 ft (1360 m).

Walk through long, dark corridors, carved by flowing lava 5200 years ago. Colorful rock formations mark the path down to the tunnels. Stalactite “icicles” hang from the ceiling and demonstrate how the cave was formed centuries ago. After this exhilarating lava cave tour in Iceland, we’ll head to our next adventure snorkeling in Silfra Fissure.

Silfra Snorkeling

We’ll stop for lunch before our next activity. Stop to buy food or bring a packed lunch. When we arrive at Silfra, we’ll be greeted by a PADI certified snorkeling instructor who will explain safety precautions and introduce you to the gear. Once we’re all geared up, we’ll head towards the entrance of the fissure.

Snorkeling at Silfra Fissure was rated as one of the top 5 activities in the world by TripAdvisor. The site might not look like much from the outside, but a whole new world opens up once you’re submerged under the water. You snorkel between two continental plates: the North American and Eurasian.

The fissure is filled with crystal clear glacial water, which travels there from Langjokull Glacier for around 100 years. The water in the fissure is some of the clearest in the world, providing visibility for around 328 ft (100 m).

After around an hour of snorkeling, we’ll head back to the base for hot chocolate and cookies.

Northern Lights Tour in Iceland

After the snorkeling tour, we’ll take you back to Reykjavik where you’ll have a chance to eat dinner and relax before the Northern Lights show. We’ll pick you up from your location at 8:30 p.m. (October - February) or 9:30 p.m. (September, April, March) and travel to the site of the hunt.

The Northern lights are hard to predict and require a good understanding of weather and aurora forecast, so we can’t tell you exactly where we’re going to go. Most of the time we head to Reykjanes, Thingvellir National Park or Borgarfjordur Fjord, but the location might change at the last minute.

The Northern Lights top many travelers' bucket lists and for good reason. Once on site, you’ll witness the most breathtaking phenomena in the world. The dancing aurora illuminates the dark Arctic sky. Green is the most common color, but hues of purple, blue, rose, and red are also sometimes visible.

Our guide will take stunning pictures of you with the aurora in the background. Don’t forget a tripod if you decide to bring your own camera!
