To begin the Treasure Hunter quests you'll need to find your first map at a camp site outside of McFarlane ranch. It will appear randomly. You'll find the map inside a chest. After that, use the map and the descriptions below to find the treasure.

• Rank 1 -
• Rank 2 - go to Vente's Place near Lake Don Julio and easily make your way by the mountains to find this easy treasure.
• Rank 3 - Head to The Scratching Post, the camp where you meet the soldiers that give you the army uniform. Up the mountains, easy.
• Rank 4 - Head to Sepulcro graveyard in Mexico, just south of there are a pair of tress, head past them to reach another bunch, search the area.
• Rank 5 - Head to Casa Madrugada in Mexico, follow the map along the mountains and if you climb on foot on a cliffy part you'll find your treasure.
