We visited Bukit Lawang for 3 days and did a half day orangutan trek with Safrol, which was really great. We saw different animal species and about 5 wild orangutans. Our guide Safrol explained us different plants and animal species and prepared us a nice snack/lunch. At the end we had the opportunity to raft back to Bukit Lawang instead of walking – a very fun and refreshing activity after half a day in the jungle. All in all, the trek remained one of our highlights in Indonesia and we recommend this tour to everyone.
