From Bario it’s a 1½-hour walk to Pa’ Umor, and another 15 minutes to Arur Bilit Farm, home to Batu Narit , an impressive stone carving featuring a human in a spread-eagled position among its designs.
Take the log bridge across the small river to reach Batu Ipak . According to legend, this stone formation was created when an angry warrior named Upai Semering pulled out his parang (machete) and took a wrathful swing at the rock, cutting it in two.
This circuit should take four or five hours – maybe a tad longer if your guide is a good storyteller.
