Four Entrance Locations Explained
Multiple pathways provide access to this mysterious biome. These can be found in the Northern Blood Kelp Zone, the Deep Grand Reef, the border between the Mountains and the Bulb Zone, and the Blood Kelp Trench. The Cyclops is able to enter the Lost River through all four entrances, and can traverse the whole way into the Inactive Lava Zone.
The easiest entrance for a cyclops is in the northeast between the bulb zone and the mountains. It is plenty wide for a cyclops. This entrance offers the safest approach for large vessels, while The Blood Kelp Zone entrance is relatively safe and easy to reach.
Ghost Leviathan Juvenile Threats

The Tree Cove serves as an ideal base location due to its peaceful nature and strategic positioning near the Inactive Lava Zone entrance.
Navigation and Survival Strategies
