I first heard of Gunung Stong back in 2016, when a friend suggesting climbing it due to the beautiful Jelawang waterfall. Unfortunately, the plan never went through as it was towards the end of the year and that the mountain was closed temporarily due to raining season. I later found out that the mountain can be conquered together with two other mountains in proximity – Baha and Ayam. Together the hike is named “BAS” (Baha – Ayam – Stong).
