Mapping Subnautica will tell you the locations of leviathans on the map.

The void is everywhere around the playable terrain; it borders the Crash Zone, the Bulb Zone, the Mountains, the Underwater Islands, the Blood Kelp Zone, the Dunes, the Sea Treader's Path, the Grand Reef, the Crag Field&mdash;at all of the borders, there is a drop-off into the void. According to the Ghost Leviathan article, if you enter the void, a ghost leviathan spawns; more will keep spawning until you leave, upon which they will retreat and despawn.
