Starting with Gua Penyu, the trainers instructed the participants to switch off their torches to experience total darkness. They explored different caves with increasing difficulty over three days. In Gua Balai, they had to help each other on slippery rocks, bonding them as a group. Gua Tongkat involved squeezing through narrow passages, getting muddy and wet. They emerged from tiny holes into magnificent caverns with rock formations. Though the challenges were tough, the participants enjoyed the experience with encouragement from dedicated trainers and camaraderie with the group.
