The Main Entrances: Your Gateways to the Depths

Alright, explorers, let's get down to the nitty-gritty: the entrances. Knowing where these gateways are is half the battle. There are a few key locations where you can descend into the Lost River. Each entrance has its own challenges and advantages, so let's check them out.

The Blood Kelp Zone Entrance

This is arguably the most common and accessible entrance, a great place to start your adventure. Located near the Blood Kelp Zone, hence the name. The entrance is relatively easy to find. Head to the north-east of the Crash Zone. Keep going until you hit the Blood Kelp Forest. The entrance is a large chasm, and it's difficult to miss.

The Blood Kelp Zone is home to some aggressive creatures, like the Crabsquid, which can disable your vehicles, so make sure you are prepared. The entrance itself is relatively open, and the descent is quite straightforward, making it a good choice for first-timers.

The Grand Reef Entrance

The Grand Reef entrance, is located west of the starting location, this entrance offers a less direct route, but it's often considered safer because you can avoid some of the more dangerous creatures. This entrance requires you to navigate through the Grand Reef. This one's a bit of a maze, but it's a worthwhile journey. This entrance is a deep crevice in the seafloor. It's marked by a large, circular structure. It will be located near a giant, glowing mushroom, making it a distinctive landmark. The journey through the Grand Reef involves navigating through the reef's structures and avoiding some aggressive fauna. Once you find the crevice, the descent is straightforward, leading you to the Lost River. This entrance is an excellent option for those looking for a different approach. Keep in mind that this entry point can be tricky to navigate due to the dense terrain and the leviathans that patrol the area.

The Mountains Entrance

This entrance is one of the more treacherous routes. It's located near the Mountains biome, to the north of the Aurora. The path will lead you through a narrow and winding tunnel. You'll need to be extra careful while navigating through the area. This entrance can be difficult to find. The entrance is a narrow crevice. You will have to go through a tunnel that leads you into the Lost River. This tunnel can be a tight squeeze. This tunnel can be tight for larger vehicles like the PRAWN Suit. Because of the close quarters and the potential for collisions, you should be extremely careful. While this entrance offers a more direct route to the Lost River, it is not recommended for new players due to the presence of aggressive fauna.

Pro Tips for a Smooth Descent

Now that you know the entrances, let's talk about how to make your journey a success! These tips will help you stay safe and get the most out of your Lost River exploration.

Vehicle Prep

Before you even think about entering the Lost River, make sure your vehicles are up to the challenge. The Seamoth is a great starter vehicle, but it can be vulnerable to attacks in the Lost River. Upgrade its hull to increase its durability, and consider adding a perimeter defense system to ward off aggressive creatures. The PRAWN Suit is highly recommended. Its grappling arm and jump jets are invaluable for navigating the Lost River's tight spaces and vertical drops. Equip your PRAWN Suit with a grappling arm and a drill arm for optimal resource gathering and exploration. The Cyclops is also useful for longer trips and carrying resources, but it's slow and vulnerable, so use it with caution.

Navigational Tools

Equip yourself with the proper navigational tools. The Depth Module is essential for all your vehicles, as it allows you to dive deeper. A scanner room can be placed in strategic locations to scout the area ahead, identify resources, and locate the entrances. Sonar is your best friend. This will help you see the environment, but it can drain your power cells quickly. You can try to explore cautiously and use your lights. You can also use beacons to mark important locations like entrances, resource deposits, and potential base locations. Remember to bring a repair tool, because you are going to need it!

Oxygen Management

Oxygen is crucial in Subnautica. Always keep an eye on your oxygen levels. Bring multiple oxygen tanks. Upgrade your equipment to increase your oxygen capacity. Make sure to have a vehicle with a docking station so you can replenish your oxygen. Try to keep an extra tank in case you run out and are unable to replenish it. If you're exploring on foot, make sure to surface frequently or use oxygen plants to avoid running out. There are oxygen-rich areas in the Lost River, but they are not always accessible. Always be prepared and plan your route. Make sure to have a plan for a safe return.

Creature Awareness

The Lost River is home to some dangerous creatures, mainly the Ghost Leviathan. These leviathans can be stealthy and difficult to avoid. Be vigilant and always be aware of your surroundings. Use your sonar to scan the area and identify potential threats. Try to avoid direct confrontation. If you do encounter a leviathan, use your vehicle's mobility to evade it, or use the perimeter defense system. Be mindful of Crabsquids and other creatures that can disable your vehicles, as it can leave you vulnerable. Be aware of your surroundings to prevent surprise attacks. Bring a propulsion cannon to move objects that block your path or to defend yourself.

Resource Gathering

The Lost River is a valuable source of resources, so make the most of your exploration time. Gather Ion Cubes, which are essential for crafting late-game items. Gather resources like Nickel Ore, Kyanite, and Diamond which are essential for upgrades and advanced crafting. Plan your resource runs to optimize efficiency and minimize trips. Bring storage modules for your vehicles to carry as much loot as possible. Use the PRAWN Suit's drill arm to efficiently harvest resources. Remember to leave some resources for respawn, so you can revisit the area to gather more resources.
