Tips

• A guard at the Pokémon League gate checks the Boulder Badge, and further guards on Route 23 check the rest of your badges, so you need all eight to get past.
• There are no trainers here, but the wild Pokémon are strong, with Fearow, Primeape and a small chance of Arbok (FireRed) or Sandslash (LeafGreen).
• Many hidden items are scattered around, including a Full Restore, an Ultra Ball, a Max Ether and a Max Elixir.
• Ekans and Arbok are FireRed only, and Sandshrew and Sandslash are LeafGreen only.
• Victory Road lies at the north end, and you need Strength to get through it.
