Patag Daku is located in Libagon, Southern Leyte, Philippines.

Patag Daku, in English, means "big plain". It is certainly big but is never quite plain. It is actually a valley so dense in vegetations that novice campers and mountaineers will never come in or out without an experienced guide leading the way. But the trek to the valley comes big in every way. In mountaineering parlance, it is a major climb. Not the leisurely stroll that one might expect, the climb is an arduopus six hour journey through a maze of trees, ferns, moss, grass and big trees.
