Tips

  • Each checkpoint guard checks for a badge, so you need all eight badges to pass.
  • Nidorina and Nidorino here are high level, and a Moon Stone turns them into Nidoqueen or Nidoking.
  • Hidden items include a Full Restore, Ultra Ball and Max Ether.
  • Part of the route needs Surf to cross the water.
  • Victory Road lies beyond and needs Strength inside, so stock up on healing items first.
