|This article is about the Lava Lakes. You may be looking for the Inactive Lava Zone.|
The Lava Lakes is a cave biome in Subnautica. At 1300+ meters down it is the second deepest biome on Planet 4546B. The deepest being the Dead Zone at 3000+ meters down. It is also the hottest biome, reaching temperatures of up to 70.5°C. Within the Lava Lakes, the Primary Containment Facility can be found. This particular biome plays a major role in the story of Subnautica.
The Lava Lakes is much smaller than the Inactive Lava Zone, but has much more volcanic activity. Lava falls are a common sight in this biome, along with obsidian pillars and magma formations jutting from the walls and lakes. The biome's water has a distinct orange color. No flora can be found in this biome, presumably due to the extreme conditions.
A sole Sea Dragon Leviathan roams the vast chamber.
The chamber consists of a huge lava lake, with occasional lava falls and masses of magma. Typically, a Sea Dragon Leviathan can be found guarding the lava lake. Towards the end of the lake, five Sonic Deterrents can be found attached to obsidian mounds by cables. The purpose of these cubes are to ward off fauna from the nearby alien base, the Primary Containment Facility.
The Lava Falls can be found going from the Inactive Lava Zone above to the main chamber below. These large pits act as entrances to the Lava Lakes, and can be found near the Lava Castle. They also connect to the secondary entrance to the Lava Lakes, which can be found in a domed depression in the Inactive Lava Zone.
- The Lava Lakes was originally called the Active Lava Zone.
- The Lava Lakes is one of the only two biomes without flora, the other being the Dead Zone.
