Rusturf Tunnel

2 Pokémon can be caught at Rusturf Tunnel in Hoenn — highlighted on the map below.

Bored through the rock linking Verdanturf Town with Rustboro City, Rusturf Tunnel begins the game unfinished, and Rock Smash is required to pass all the way through. It also provides the sole access to a hidden corner of Route 116. Once the Stone Badge is earned, the player pursues a Grunt into the tunnel and recovers the stolen Devon Goods; later, smashing a pair of rocks reunites two people separated inside.
