Pokémon GO Fest Paris will take place in France, bringing a global event that offers various bonuses and exciting features. The event will run from Saturday, June 14 to Wednesday, June 18, 2025.
During this event, the chance to encounter Shiny Gothita and Shiny Phantump increases, while Gigantamax Inteleon makes its debut in six-star Max Battles. Trainers with a Phantom Wilds ticket will also receive double catch Stardust bonuses.
In addition to these features, Pokémon will be attracted to Incense more frequently, including Rhyhorn evolving into Rhyperior and Shadow Excadrill. Other Pokémon like Dusknoir, Drapion, Golruk, and Sableye will appear in Wild Encounters or be available with Incense.
To participate in the event, trainers can complete Collection Challenges, Field Research tasks, and purchase an Ultra Ticket Box for $1.99 (or equivalent). The Ultra Ticket Box includes an event ticket and five Ultra Balls at no additional cost.
