Christine from Discover Sumatra was very helpful in organising my days in Bukit Lawang including two day jungle trek. She answered all my questions and organised transport from Medan and accomodation in the village as well as the trek. The trek was fantastic, saw lots of wildlife and the scenery was great. The walk was challenging but the guides were very helpful and the food was great the whole time. In Bukit Lawang Safrol met me a couple of times to check in with me and make sure everything was ok. This was very much appreciated and he was a super guy to meet and talk with. In total I had 5 days in Bukit Lawang, including 2 day trek. The village was beautiful and everyone was very friendly and nice. I enjoyed the trip very much and want to thank everyone involved for making it a great trip. Definitely recommend using Discover Sumatra.
