The treetop hideout was the headquarters of Jet and the Freedom Fighters. Situated in a forest near the village of Gaipan, the hideout consisted of an upper and lower canopy, as well as a camouflaged base of huts connected by zip lines, ladders, and rope bridges. Its location gave it a strategic advantage, as it ensured that it would remain concealed from enemies. A sharp tug on a secret rope allowed entry into the hideout.
When Aang and Katara aided Jet in filling the nearby dam with water, the latter secretly plotting to flood Gaipan, the two were told to meet Jet back at the treetop hideout. However, Katara insisted on heading to the dam rather than the treetop hideout as planned, believing Jet would be glad to see them.
