The rim is irregular with 2-km-tall jagged peaks that project prominent shadows across the crater floor when the Sun is at a low angle.

Sections of the inner wall display signs of past slumping, most notably a large triangular slide along the western side.

The flat floor of Plato has a relatively low albedo, making it appear dark in comparison to the surrounding rugged terrain.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Plato.
