The best place to train Agility depends on your current level. Lower-level players can start with the Gnome Stronghold Agility Course or the Draynor Village Rooftop Course. As you progress, you can move on to courses like the Seers' Village Rooftop Course, the Ardougne Rooftop Course, or the Pollnivneach Rooftop Course. Higher-level players can train at the Rellekka Rooftop Course or the Hallowed Sepulchre. Each course offers different experience rates and requirements.
