FAQ

What is the best time to dive Silfra?

Silfra is available to dive all year round.  Typically, the summertime is always the best time to take advantage of dazzling light displays and more pleasant outside changing conditions.
Wintertime can present a tougher experience on the body because of the cold air temperature. However the visibility can be even better during the winter months, and you have the chance to experience a true white winter wonderland. Whatever time you decide to visit Iceland, choose sensible clothing and adequate thermal protection.

Why is Silfra a challenging dive?

One of the world’s top dive sites it may be, but also challenging for two good reasons. Firstly, the water temperature goes down to 1 ℃ and secondly, there are lots of different depths to explore. This creates a thrilling arctic experience, that can sometimes, without the correct buoyancy control – overwhelm divers, making them go to the surface without stopping. This can lead to injury or even worse. Our advice to anyone that thinks they lack the confidence to dive Silfra would be to snorkel instead – its a lot safer.

Do I need to be drysuit certified to dive Silfra?

A drysuit certification is required or proof of 10 logged drysuit dives. 

Is there any aquatic life at Silfra?

Each spring, bright green algae finds life on volcanic lava rock, dancing in the gentle current, close to the silent groundwater springs entering Silfra. This elegant plant then blooms in the summer months before beginning its inevitable decline towards the winter.

Throughout the year, small Arctic char live amongst the darkness, between the cracks and under the crevices at Silfra. They can often be seen hiding but are quickly scared away.

On rare occasions, magnificent giant Trout from lake Thingvallavatn swim upstream into Silfra in search for food. Over the many years, both species have evolved to survive together in extremely cold water (1-4℃). They play an important part for preserving the natural balance in the circle of life within Silfra.

How do I get to Silfra with my own transport?

Getting to Silfra by car takes about 50 minutes drive from Reykjavik. The road will take you north east through Mosfellsbaer before heading along the Thingvallavegur mountain pass and finally into the Thingvellir National Park.

Once in the national park follow the signs towards “Thingvellir” and “Silfra” until you reach the parking site called “Thingvellir P5”
