The Dungeon of the Snake is located on an island south-east of the Royal City and north-east of Montor. It can be accessed by ship, but also using the Moongates. It is the only dungeon that conceals the Mark of Snake, therefore it is the only absolutely mandatory dungeon.
It's probably the easiest dungeon, because it has the lowest number of traps; also, it has a small number of chests, but they can be randomly trapped, too. All in all, a good choice to begin with dungeon exploration.
The Dungeon of the Snake was renamed "Cave of Sol" in the NES version. In the NES, the Cave of Death (i.e. Dardin's Pit) is mandatory, too.
