The world ofStardew Valleyhas expanded massively over the last six years, filling out the indie farming RPG with dozens of hours of content. The story doesn’t end with Pelican Town, and players will find themselves journeying to some far-flung places in search of new adventures. One ofStardew Valley’s most dangerous destinations is Skull Cavern, which contains great loot along with hordes of powerful monsters.

SV Calico Desert

Getting toSkull Cavern isn’t easy, and new players probably won’t reach it until at least the latter half of their first year on the farm. At the start of the game, players won’t even be able to reach the outside of Skull Cavern, let alone descend into the depths, and there are a few things to do before it’ll unlock.

Unlocking the Calico Desert in Stardew Valley

Before players can access theSkull Cavern inStardew Valley, they’ll first need to reach the Calico Desert region. This is one of the few areas of the map that isn’t immediately available to players, and can only be reached by repairing the desert bus.

To repair the bus, players must either donate the full 42,500g to the Vault Bundles in theStardew ValleyCommunity Centeror pay for the bus to be restored on the Joja Community Development Form for 40,000g. Once either of these has been completed, Pam will be available to drive players to the Calico Desert between 10:10am and 5pm every day. Tickets cost 500g and include a return trip to Pelican Town.

Once in Calico Desert, players will be able to find the entrance to Skull Cavern in the northwest of the map.

Finding the Skull Key in Stardew Valley

Unfortunately, finding Skull Cavern is only the first step to unlocking it inStardew Valley. The door to the Cavern is locked, and players willneed the Skull Keyto enter. This key is found at the very lowest level of Pelican Town’s Mines, on Floor 120. The Mines are the first combat area that most players will encounter inStardew Valley, but get progressively more challenging the deeper they go.

Players will have to fight their way down through all120 floors of the Minesto reach theSkull Key, gaining valuable experience along the way. The Skull Cavern is very similar to the Mines in playstyle, albeit with a sharp spike in difficulty. Therefore, players should prepare for a tough fight by equipping a good weapon and some buffing foods.
