The wind blows hard, making a loud noise when it hit the tent wall. The temperature drops to below zero degrees Celsius. We are all safe and warm inside our sleeping bags in the tent. But our thoughts are out there, thinking about our friends who are still out there trekking from Bali Dump heading to the basecamp at an altitude of 4,330m above sea level, where we set up our camp. Walking through Meren Valley (Lembah Danau-danau) and Pintu Angin during the night amid strong winds and low temperatures like this, our physical condition would be easily and quickly dropped. The falling rain would also further hamper their trip and make it more difficult..
