Unknown Great Forest

The Unknown Sea of Trees is a forested area introduced in Monster Hunter 4. Characterized by the massive ruins and architectural elements seen among the environment, this area appears to have been richly inhabited by humans at some point in its history. Now, however, the structures are ancient and crumbling, with thick overgrowth evident as nature continues to reclaim the area.

In its abandoned state, it is home to many wild monsters, such as Tigrex and Garara Ajara. Hunters can use various architectural elements such as ledges and pillars to their advantage during combat with a large monster.
