Subnautica Lost River: Entrances and Tips for Exploring this Biome

Hey there, fellow Subnautica explorer! If you're reading this, you're probably itching to dive into the depths of the Lost River. Well, you're in luck. I've got all the insider tips and tricks to help you navigate this mysterious underwater world. So, let's get started!

The Lost River isn't just another biome in Subnautica - it's a whole new world waiting to be discovered. It's deep, it's dangerous, and it's teeming with resources and secrets that are key to the game's storyline. But remember, it's not a walk in the park. You'll need to be prepared for a lack of oxygen and some pretty scary creatures.

Before you embark on your journey to the Lost River, it's crucial to prepare adequately. Your first priority should be transportation. Given the depth and dangers of the Lost River, a Seamoth with a Depth Module MK3 is a good starting point. However, for a full-scale expedition, a well-upgraded Cyclops, equipped with a Sonar Upgrade, Depth Module MK1, and a docked Prawn Suit with a drill arm, is recommended.

Next, you'll need supplies and personal equipment. Consider installing a grow bed in your Cyclops to grow Marblemelons, ensuring a steady supply of food and water. A Reinforced Dive Suit, a Stasis Rifle, and a Repair Tool are also essential for your safety and survival.

The Lost River, a fascinating area in Subnautica, isn't just accessible from one point. In fact, there are four different entrances that you can use to get there, each offering its own unique advantages.

The Blood Kelp Zone entrance is relatively safe and easy to reach. To find it, head to the beacon for Lifepod 13, which will lead you to the Mushroom Forest biome. From there, follow a slight northeast bearing until you reach the edge where the Mushroom Forest and Blood Kelp Zone meet. Look for a cave entrance with green brine on its bed - that's your gateway to the Lost River.

The second entrance is also in the Blood Kelp Zone, but it's closer to the Dunes and thus more dangerous due to the presence of Reaper Leviathans. To reach this entrance, head to Lifepod 17 in the western Grassy Plateaus, then head slightly southeast. You'll find a large trench leading to the entrance.

The third entrance is located in the Sparse Reef, close to the Grand Reef. This entrance is less ideal for a Cyclops due to the presence of Crabsquids. However, if you choose this route, head to the Degasi Base in the Grand Reef and then follow a northwest bearing until you reach the entrance.

The last entrance is in the Mountains/Bulb Zone. While it's easy to navigate with a Cyclops, this area is teeming with Reapers, making it a risky choice. To reach this entrance, follow a northeasterly arc from your Lifepod, passing through the Grassy Plateau and the eastern Mushroom Forest until you reach the Bulb Zone. From Lifepod 12, head due north to find the entrance.

The biome is filled with a green brine that is harmful to the player but safe to traverse in a vehicle. The Lost River is home to unique flora and fauna, including the Ghost Leviathan Juvenile and the River Prowler.

The Lost River also contains several points of interest, such as the Lost River Laboratory, the Disease Research Facility, and the Giant Cove Tree. The biome is rich in resources, including large deposits of Nickel Ore, Crystalline Sulfur, and Uraninite.

Remember, the Lost River is a dangerous place. Always keep an eye on your oxygen levels, vehicle health, and the creatures around you. It's easy to get lost in the depths.
