Route 47

Route 47 is a route in Johto. 
A local landmark is Cliff Cave. It is one of the brand new areas of Johto, along with the Cliff Path, the Safari Zone, and the Embedded Tower (where you can catch the Legendary Pokémon Kyogre in HeartGold, Groudon in SoulSilver and Rayquaza, which is found in both). To reach every area in this Route, you need Surf, Rock Climb and Waterfall.
The route itself is beautiful with its two waterfalls. Occasionally, at a certain point in the game, you can go and meet Crasher Wake.
