|Location||Brimhaven dungeon; Baxtorian falls west of Fishing Guild; Fire giant dungeon, Member's Wilderness; Smoke dungeon, west of Pollnivneach; Chaos tunnels; Baxtorian Falls Resource dungeon|
NotesThe best location for Fire giants is in Brimhaven dungeon or the Chaos tunnels (for meleeing) and Baxtorian falls (for rangers or mages). You will need to bring 875 Coins with you (or Karamja gloves 3 for free) if you intend on going to Brimhaven Dungeon Fire giants, and a hatchet.
If you however decide to train at Baxtorian falls, you will need a Rope and Glarial's amulet in your inventory to bypass certain obstacles, and to be able to successfully enter the cave. Also in the Baxtorian falls dungeon there is a Dungeoneering Resource Dungeon that contains Fire giants. It requires level 35 Dungeoneering to enter and is a great alternative in case the normal Fire giants spots are crowded.
The Chaos tunnels are the closest spot to a bank, are rarely crowded, and are a multi-combat area. Also, a great place would be the Smokey dungeon, as it's easier to fight there. However you must wear a Face mask or Slayer helmet while in the Smokey dungeon.
