How do you get into the dragon den cave silver?

To get into the Dragon Den cave in "Pokémon" games, you typically need to have defeated the Elite Four and acquired the necessary badges to access the area. In some versions, you may also need the Surf ability to navigate through the water. Once you reach the cave entrance, you can explore it to find the rare Dragon-type Pokémon and gather items, including the Silver Wing in certain game versions. Make sure to check specific game guides for exact details, as the requirements can vary by game.
