Secret Grottoes are unique caves added by Relics of Hyrule that cannot be found on the map like normal locations. A total of nine Secret Grottoes exist: one for each hold of Skyrim. Some locations may be dubiously considered Secret Grottoes.
Every Secret Grotto contains at least one Gold Skulltula.

Background and Inspiration Edit
JKalenad has plans to add a proper Solstheim Secret Grotto in a future update. He does not consider Vetrianaav, the Forgotten Cavern, or the Golden Goddess Shrines to be Secret Grottoes.
The Secret Grottoes were included to provide locations for hidden treasures and to reward exploration. Prior to the introduction of Fairies, the grottoes were very difficult to find. The grottoes also did not have map markers until version 6.44. JKalenad resisted adding markers to the grottoes, reasoning that they were meant to be secret and visited rarely. However, once the grottoes were expanded, they were made easier to find and revisit. JKalenad discovered a means of activating map markers after the player enters the grotto, allowing their whereabouts to be initially secret.
