Glistening Grotto is a cave considered as an extended area in the savanna on Route 5. HM6 Rock Smash and the Crater Badge are required to gain access to this place. The cave has shiny dazzling crystal pieces scattered around the walls, hence the name.
Upon entry, a fork instantly splits the path, with the right path leading towards a waterfall and a slope further inside which contains Sablenite at the end. Both paths are surrounded by a multitude of shining crystals and will lead the player deeper into the cave, converging twice and eventually ending as a U-turn.
Note: Rarity levels are estimations according to this scale and might be subject to changes due to different encounter assessment results, unless supported by official encounter rates, which are listed in red under the rarity level if known. If there are any Pokémon with low catch rates, the possibility to flee or requirement of gaining happiness to evolve, recommended Poké Balls for that Pokémon will be shown with the corresponding bag sprite under the Pokémon's name.

- The glowing crystals in the area are parallel to those on Route 13. They are also similar to the crystals found in Cragonos Spring, except notably more colourful.
