Fantastic. Professional. Recommended.
We joined a tour from Sepilok to Sukau Rainforest Lodge with a boat transfer from Sandakan. The whole experience was (a) exceptionally well organised, (b) professional and (c) truly memorable. The guides were very friendly and polite as well as being incredibly knowledgeable. There tours were organised at sensible times to Maximise the chances of seeing the wildlife. The hosts at the lodge were extremely welcoming and generous.
Would highly recommend these guys.
