Johto Route 37

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. This road makes its way north from Route 36 and loops around a small tree, where a pair of Twins are training together. From there, a large gap in a wide ledge, which allows the path to continue north past a large patch of tall grass, several more Trainers, and a signpost, until they reach Ecruteak City.

However, the eastern half of the route holds greater treasures for Trainers. Unlike the western side, this path can only be traversed in one direction; north-to-south. The path begins by jumping a small ledge, which presents three Apricorn trees in a small clearing between the ledge and a patch of tall grass. This is also the location of one of the Week Siblings, Sunny, who appears on Sundays, giving out a Magnet to Trainers who meet him for the first time, and a Smile Ribbon after the first meeting with him. The stretch continues south past the patch of tall grass, until it connects with the western half at the southern entrance.

Route 37 in Pokémon Adventures

Pokémon Adventures

Gold, Silver & Crystal arc

In Smeargle Smudge and How Do You Do, Sudowoodo?, a bicycle race between Gold and Whitney had its goal set at the Route 37 signpost. However, the route turned out to have been blocked by a strange tree, which seemed to be unaffected by the attacks Gold and Whitney threw at it. Suddenly, a Rhydon appeared and took Whitney captive. Gold soon found out that the tree was actually a Sudowoodo, who had disguised himself as a tree to avoid being detected by Rhydon. Gold subsequently caught the Sudowoodo and used him to save Whitney.

HeartGold & SoulSilver arc

In Out-Odding Oddish, Gold and Whitney traveled through Route 37 on their way to the Pokéathlon Dome.

• In the demo version of Pokémon HeartGold and SoulSilver, the player starts on Route 37.
