Pewter City is located within the north-west of Kanto, surrounded by cliff-faces. This city has a few important areas such as a tree with rare Pokémon on it and a man who will give you the Rainbow Wing/Silver Wing.

Pewter Museum
At the north part of the city is the Pewter Museum, inside which there are lots of artefacts. In this museum, you can convert your fossils into Pokémon. However, if you take the Enigma Stone here, it will activate Latios/Latias who will appear outside with Steven Stone.

Cameron's Photos
On Tuesdays & Saturdays, Cameron the Cameraman will appear outside the museum and will take photos of you and your Pokémon team.
On Mondays & Sundays, Cameron the Cameraman will appear in the middle of the museum and will take photos of you and your team.

Gym
The Pewter City Gym is one of the gyms of the Kanto region. This gym follows a fairly linear path up to the Gym Leader with trainers located on the path. These trainers can be bypassed through a side-path until you reach the Gym Leader; Brock. Earning the Boulder Badge does not give access to any hidden moves outside of battle.
