When it comes to chance underwater encounters, seeing a great white shark on an open-water dive may just be No. 1.

Divers travel across the globe to spots such as Isla Guadalupe, Mexico, South Africa and South Australia for the chance to spot these majestic sharks from inside cages. These experiences are specially tailored to see great whites — these sharks don’t just show up on many open-water dives.

“No threatening behaviour at all. Truly a rare encounter, envied by many,” wrote the operator on Facebook.

That’s a dive that will not soon be forgotten.
