During Eid Al Fitr break, my brother went to a cave that I went. He brought his kids and wife, and also our parents as my dad is the tour guide.
Last year I was able to come home and went around with my dad to explore his place and so he brought me some places including the cave where my grandparents hid during from Japanese soldier in WWII. Apparently my brother never been there and he was envy when I showed him the pictures.
Arguni Cave, Fakfak.

They need to go through a jungle to get to the cave.
Please be patient when seeing 25 minutes of video as my brother is still learning how to edit a video. You can fast fwd to see the cave.
