It's a 'chun choi' world out there

The photos show Mount Sinabung at the background. According to stories we heard from our tour leader, Roni, Mount Sinabung was actually part of Mount Sibayak. However, due to the volcanic explosion many many years ago, Mount Sibayak split into two now known as Mount Sibayak & Mount Sinabung. It's like a mountain giving birth to a mountain. They are like sister-mountain. They are located not far apart but they have distinct differences in their appearance. Mount Sinabung is now opened to climbing enthusiasts. To conquer its height needs about 2-3 days. There are guides to lead the way. Hm.... maybe I should let my travel mates plan this climb and get more people to come and conquer this mountain. Should be fun. And since it was former a volcano, it would be more interesting compared to Mount KK in Sabah. Anyone with opinion on this?
