The National Park (Japanese: しぜんこうえん Nature Park) is a location in Johto. It is located to the north of Goldenrod City, between Route 35 and Route 36. The Bug-Catching Contest takes place there every Tuesday, Thursday and Saturday.There is no entry fee for the Bug-Catching Contest. Anyone may enter once per day, every Tuesday, Thursday, and Saturday.
To compete, Trainers must catch the single best Bug-type Pokémon they can find. To do this, Trainers are given twenty Compe Balls, which are similar to Safari Balls, and allowed use of a single Pokémon of their party. The rest of a Trainer's Pokémon and any items they may have remain with the contest officials until the competition is over. The competition ends when all the Compe Balls are used, or when Trainers leave the way they came. After that, the judging will occur, where Trainers are scored on their skills of capturing rare and exclusive Pokémon.
