My wife and I recently had the good fortune to visit Japan and South Korea for a total of seven weeks and while in the latter country, I took the opportunity to go for a walk or two.

The idea of trekking in the Sumatran jungle and visiting Lake Toba had been on my ‘bucket list’ for years. I had found very little information on the internet, it seemed few people trekked there for any more than three days. In the end I opted for a commercial trek with Expedition Jungle who offered a seven day trek across the Gunung Leuser National Park from Semadam in Aceh to Bukit Lawang in North Sumatra.
