Augmented-reality technology is changing the way we travel and experience new places. At Pokémon GO Fest Chicago 2019, we had visitors from 68 countries and regions. At Pokémon GO Fest Dortmund 2019, half of all visitors were international and came from 90 different countries and regions. UNWTO’s mission is to promote and support responsible, sustainable, and universally accessible tourism, and we’re so proud to be partnering with an organization who shares our values of exploration and adventure.
Keep these steps in mind when traveling to make your travels rewarding for you, the people you meet, and the places you visit—let’s GO!
—The Pokémon GO team
