Trans GBB (Gerah, Bilah and Bieh) via Pos Kemar, Kg Lelar

With Hiking Passion Adventure group

Note: This is a continuous tracking, over 4d3n. And thanks to Wikiloc's maximum allowed waypoints, I decided to not mark, all of the streams, rivers and/or bridges (and there are many!). Instead, I decided to ONLY mark, only major landmarks, and those rivers/streams, where y'all can never avoid, to get wet. So, if y'all ever decided to attempt this trail, don't ever wear waterproof boots/shoes. Once those gets wet, it'll be near impossible to get it dry, for the next-day hike. Trust me, hiking on such difficult trail, using wet boots, sometimes for more than 10 hours, is not fun.

Originally 5d4n, became 4d3n, with the 4th night, spent at Pos Lelar's village. We decided not to camp at Junction Campsite, on Day 4, and pushed on out, all the way, to Pos Lelar, from Perodua Campsite.
This trip, was originally planned, 2 years ago. But then, COVID happened, and still is happening. However, finally, we managed to do it. But of course, the last trip done, by other groups, was 2 years ago, so, y'all can imagine, how Mother Nature, would've retaken the trail. And retake the trail, She did. Had to spend hours on certain sections of the trail, and reopen the route. And damn, this trip was tough. Both in terms of technical difficulty, and the distance+elevation. But at least, another one off, off my hiking destinations' wishlist

Campsite Note:
So far, each Campsite's filled to the brim, with mosquitoes and worst of it all, SANDFLIES! No leeches, so far, though some did commented that they got some. So, maybe I was just lucky?
