The Flooded Forest is a location introduced in Monster Hunter 3, it's a large forested wetland with many sections partially, or even completely, submerged. This habitat is ideal for a large range of creatures, including most aquatic Leviathans (Lagiacrus, Royal Ludroth, Ludroth, and Gobul) and a variety of insects and mushrooms.
Due to the removal of underwater battles in MHP3rd, the Flooded Forest was revised. Areas 3, 5, and 6 are no longer completely underwater. Areas 4 and 8 have been modified to no longer have any deep water (water deep enough for the hunter to swim). Also, the shortcut to Area 6 has been removed, these revisions were revoked in Monster Hunter 3 Ultimate.

Strangely enough, if you stay submerged in Area 8 long enough, an ambient tune will start to play, even if your music volume is set to "Min". It is both eerie and tranquil.
There is a one-way shortcut to Area 6, which can be found by diving into the water to the West of the Base Camp and swimming through the cave.
Location: Area 6 (access from Area 4). If in MHP3rd, base camp near the bonfire.
