The tour is great!
The route choices, the boat crew are very helpful especially Hana. The food is really awesome!
One thing that need to be aware of is the snorkeling time is very limited, only 30mins. So it’s better to ask them when in Racha Island to maybe accompany you for another private snorkeling time during the first 1,5 hour, with of course more money.
You can only buy food and snacks on Coral Island since in Racha there isn’t any store that sells snacks, only one small stall that sells juice and instant noodles.
Overall, the experience is nice and will be going with this tour again in the future!
