For a bucket-list diving experience, Iceland’s Silfra fissure is truly unmatched. Situated in Þingvellir National Park, this extraordinary chasm marks the divide between the Eurasian and North American continental plates, making it the only place on Earth where you can dive between two continents.

The crystal-clear glacial water offers unparalleled visibility, allowing you to see almost the full length of the 328-foot (100m) ‘Cathedral’ section. As you glide through this otherworldly gap, you’ll spot boulders draped in neon-green algae – affectionately nicknamed ‘troll hair’ by locals –creating a mesmerising scene in one of the world’s most remarkable geological wonders.

The ultimate bucket list for adventure lovers, ranked
