Dunbarrow Cove is a cave located behind and under Anvil Castle. The first section of the cove is called Smuggler's Cave and contains some crates, chests and barrels and can be accessed in the vanilla game.
However, the lower passage leads to Dunbarrow Cove itself, which is only available with The Thieves Den plug-in, while the upper passage, which can only be opened with the Smuggler's Key, leads to a secret section of Anvil Castle and ends up in the Umbranox private bedchambers.
The Smuggler's Key can be found in the chest at the foot of the bed inside the Captain's Quarters after having been upgraded.
