There were about 50 guests and it felt like an adequate number of staff. Activities: The conditions weren’t ideal for snorkeling but that’s of course not the company’s fault. The kayaking, however, was lovely. There was an opportunity to kayak a second time as well. A highlight for me was climbing to the viewpoint on Wua Ta Lap Island. This is no joke of a hike as it’s 500 meters up steep uneven…”

We sailed to koh Tao first with a speedboat that had very high windows, so we couldn't see the way, and the way wasn't bumpy at all.
