The Sacred Bog is a location in Point Lookout, reached via the Sacred Bog Entrance on the easternmost side of the map. It is a winding path through the swamp, populated by various swamp creatures.
The Bog is populated with swamplurks, mirelurk hunters and swamplurk queens, all of which are found along the path towards the Mother Punga, a very large variant of the punga plant. Many punga plants can be found here, including 35 punga plants around the Mother Punga alone.
Directly North of the Sacred Bog Entrance is a burned out house with some loot.
The water inside the Sacred Bog has unusually low levels of radiation; drinking from most bodies of water inside the bog will heal 20 HP while only causing an increase of 1 unit of radiation. The exception is the body of water immediately prior to the Mother Punga plant, which has a normal level of radiation.
Upon entering this location, fast travel is not available until you exit from sacred bog entrance.
