The Brimhaven Aztec Agility Temple is one of the best and most exciting ways for your to get agility experience along with many other cool prizes,it contain a lot of pieces. First of all, bring lots of food. GOOD food! Be aware that pets can not be taken into the Brimhaven Agility Arena.
Second, head to Brimhaven and just north of the gate into the members area of Karamja Island, you will see a little bamboo hut. Talk to "Cap'n Izzy No Beard". It takes 200 coins to enter the temple. As soon as you enter, you will get the music "Aztec" (Note: Bringing teleport runes would be a good idea, as you never know when you'll be stranded without food.)
The Object of this temple is to follow the blinking red arrow on the map to each ticket dispenser. You will have 30 - 60 seconds before the arrow changes to reach them.
Once you find the right area, the arrow will be blinking yellow. Click on the ticket dispenser to receive a ticket.
Now rush to the blinking red arrow again, it will turn yellow when you are close to the ticket dispenser, and click the next ticket dispenser. You will get an agility ticket! From now on, every one you reach before the time runs out will give you a ticket. If you fail to get one because it moved, just start over (whenever the little red/green light in corner is red you need to start over). Note: The first time you click a dispenser will not give you a ticket.
