Detailed Information regarding Garchomp’s Location and the strategy to encounter it in Pokémon Sun and Moon.
How to Get a Gabite
You can encounter Gabite at the Haina Desert in Ula’ula Island only during a sandstorm. Be sure to catch one when it intrudes a SOS battle. Because you will be battling under a Sandstorm, using a Rock, Ground, or Steel type Pokemon is highly recommended.
How to Get a Garchomp
Gabite will evolve into Garchomp at Lv48.
It has high Attack and Speed, making it an excellent attacker. Its speed is one of the best when looking at it as an Ground-type Pokemon, and will be able to play advantageously in battles since it will outrun most opponents.
