Swamp Encounter Locations

Swamps include gloomy temperate wetlands, jungle marshes, areas of mangroves and treacherous bogs. Buildings are often old ruins or raised from the waters. Quicksand and swamp gas are found here, alongside stagnant pools teeming with insects and a rickety jetty with a coracle or boat tied to it.

There is a 5e Swamp random encounter generator at ChaosGen. And a separate tool for encounter locations including Swamp.

There is also a pdf of these and more tables at the DM's Guild as Swamp Encounters.
