Dig Piles are piles of dirt that can be digged up. At the bottom of a dig pile there is usually treasure, a carrot or a Moler. Some Dig piles are found on walls; these when struck release a ball of gravel that only needs be struck once to release the treasure inside.

The Dig piles in The Lich Yard have a slightly different appearance with bones sticking out.

After dying and restarting at a Checkpoint, any treasure already collected in the stage will not be reset. As such, every Dig Pile that has previously been excavated will be reduced to it's smallest state. If unearthed again it will only contain either a carrot or a Moler. The carrots sometimes contained in Dig Piles are useful in New Game Plus where food is much harder to come by.

In Shovel of Hope, the smoldering campfire set by Shovel Knight after a stage of the Valley is treated as a dig piles. Digging it up unlocks the Only You Feat. When the Shovel Blade has been upgraded with the Trench Blade ability, Shovel Knight can dig up Piles in one fell swoop. The Fishing Rod Relic can also be used with the same results, as well as the Shovel Drop executed while wearing the Armor of Chaos, or the finishing combo boot move executed while wearing the Toad Gear. The Hedge Farmer in the Village has a dig pile next to him that gives nothing. If Shovel Knight digs it up he shows his admiration. If the Trench Blade upgrade is used he is even more impressed. If the Fishing Rod is used, he comments on your unusual methods.

Custom Knight also has its personal options for digging a pile in one motion, its versions of the Bait Bomb and Fleet Flask, his Charge moves Flare Razer and Bomb Burst and Special moves Shovel Blade Max and Bounce Bomb.

In Plague of Shadows, Plague Knight can blow up completly a ground dig pile in a single hit with all types of powder of his bombs as well as the Basic Burst and Float Burst explosions and the Big Boom, Bait Bomb, and Fleet Flask Arcana. Some of the dig piles contain a Health Tonic.

In Specter of Torment, Specter Knight can dislodge dig piles stuck in wall by jumping on them while wall climbing. He also has a few different options for digging a ground pile in one motion, such as the charged attack of the Striker’s Shawl, the flames of the powered-up Raiment of Risk (both of which can be combined with the Shadow Mirror), and the Curios Dread Talon, Spider Scythe, and the Skeletal Sentry's explosion.
