We take you where few diving tours in the world can – into the continental rift between the North American and Eurasian tectonic plates! Thingvellir National Park is home to Silfra fissure, an out-of-this-world subaquatic rift.
Silfra fissure in Iceland has become widely known in the last few years. Divers agree that this is one of the best freshwater dive sites in the world. Glacier water from Langjökull glacier that has been filtered through the lava field on its 50 years-long journeys to the fissure is so clear that the visibility is about 100 meters. Silfra is divided into four main sections that we will explore during the tour.
The water in Silfra is at a constant 2-4 degrees celsius throughout the year but all seasons have their charm under the surface. Silfra is situated in the heart of Þingvellir National Park, the founding place of the world’s oldest parliament and a UNESCO world heritage site. Silfra is an otherworldly scene located in the lava field directly on top of the continental rift valley between America and Europe.
Usually one does not want to be between a rock and a hard place but in the case of Silfra, you want nothing more. Experience the weightless floating through the clear glacier water going in between the tectonic plates. The slow current gives one a perfect pace to explore this beautiful area. The freshwater visibility is an unmatched specimen, so wide and long that sometimes it is only limited by the density of the water itself.
Depth varies from 10 to 40 meters. Our dive depth is limited to 18 meters by park regulations. This is without question one of the best dive tours the world has to offer. If you are a keen diver, make sure not to miss it! Be aware that this is a challenging dive where you need to be capable of carrying heavy equipment up to 400m.
Thingvellir is a historic site, a national park in Iceland, and a UNESCO heritage site. Initially known for being the place where Alþingi (the parliament) first took place in 930, this place had served a significant role in Icelander’s saga since the settlers came. Still today, you can find ruins of old stone shelters, the lakes, and the Lögberg (Law Rock). The park sits on a rift valley caused by the separation of two continental plates, with rocky cliffs and fissures like the huge Almannagjá fault. In this separation sits the remarkable Silfra fissure.
On arrival to Silfra, dive guides will give a thorough dive briefing. This will include details about diving procedures, signs and signals, national park rules, your equipment, the route, and important information on how to use the drysuit.
Once you’re geared up, it’s time to walk to the entrance and get in the water. Entry is via steps that lead onto a large metal platform. The water will be waist deep as you stand on the platform so you can easily acclimatize to the feeling of the cold water on your face, and have a quick drink of the refreshing water. After each diver has done a weight check with the dive guide, it’s time to begin the dive!
You’ll be taken through each of the four sections of Silfra, and have plenty of opportunities to have a good look around. The first section near the entrance is the Silfra Deep Crack, which is long and narrow as it winds a little to the left and right. This then widens slightly into what we appropriately call the Silfra Hall, which leads to the deepest point at 22m called the Silfra Cathedral. After the cathedral, we turn left into the Silfra Lagoon, which is incredibly beautiful and the final part of the dive. After stepping onto the exit platform, your guide will help you remove your fins and you’ll have a chance to warm yourself up with roughly a 300m walk back to the car park. We can always remove your weights or even your gear if you have trouble walking with your gear on, and you can also have a rest back at the entrance which you will pass on the way back.
Once back in the car park, we’ll take the gear off you and get the hot chocolate and cookies out so you can warm your hands whilst you talk through the dive.
