Silfra fissure is near the top of most scuba divers bucket lists because it allows you to swim between two continents. The dive takes you through a crack between the continental plates of North America and Eurasia and in places it is possible to touch both at the same time.
The dive is also thrilling because it offers visibility of more than 100 metres because it is glacial water, which has filtered through porous underground lava for 30-100 years.
Few fish venture as far as the fissure but the coral landscape is stunning and well worth enduring the colder temperatures.
Best time to dive: The site can be dived all year round but it can get crowded during summer months.
Water temperature: 2° – 4°C, so a full wetsuit is required
