Route 36 is a north-south, as well as an east-west route located in central Johto. Its northern terminus is at Route 37 south of Ecruteak City, its southern and western termini are at Route 35 and the National Park, respectively, and its eastern terminus is at Violet City. Heading south from Ecruteak, Route 36 is split in half by a series of trees. The western half proceeds south, passing a Trainer duo before merging with the eastern half southwest of a grass patch that blankets the southern portion of the eastern half. Now one route, Route 36 continues south, turning to the east and becoming extremely narrow as it meets the Route 35 connector path.

Route 37, the eighth route encountered in Johto, is the shortest route within the region. Route 37 begins not too far north of where Sudowoodo was found on Route 36. On its western half, there is a bi-directional path which trainers can take both to and from Ecruteak City, however, its eastern half holds true goodies in the form of several Apricorn trees in a small clearing between a ledge and long grass. This is also the location of one of the Week Siblings, Sunny, who appears here on Sundays to give trainers a power-boosting item.
