The route begins rather high up as Trainers exit from Cliff Edge Gate, and heads due west past a Hiker, where it takes its first branch. From here, Trainers can go north two paces and into Cliff Cave, which connects the various levels of the route, or continue westward across a bridge in front of a roaring waterfall. There is very little across the bridge, however, as only a Camper appears, separating the player from a Revive.
Inside Cliff Cave, the player can either go up or down; each path contains its own perks. Going down and out from Cliff Cave leads the player to the sea, where they can explore, and with HM07 (Waterfall), climb to the only tall grass on the route.
Further west is another waterfall; climbing it will lead the player to a White Flute, otherwise obtainable only via transfer from Generation III or trading with Platinum.
The upper path will take travelers to Route 48 and Johto's brand-new Safari Zone; a Double Team waits to challenge any player exiting the Cliff Cave. Passage is free to the west, across several bridges over beautiful waterfalls, and eventually onto a grassy path near a billboard advertising the Safari Zone. North of here are the final Trainers on the route, a Young Couple, and a bit further north, Route 48.
Accessible only with HM08 (Rock Climb), Embedded Tower is the whereabouts of KyogreHG, GroudonSS, or Rayquaza (if both are captured and shown to Professor Oak). West from the entrance to Embedded Tower is the westernmost accessible point in Johto, a small spit of beach at the bottom of climbable rocks.
