The Boonsiri Ferry from Laem Sok Pier to the island of Koh Kood
Update March 2021.
Travelling in these times is a pleasure, as there are not many people travelling(currently only Domestic travellers) but also full of challenges with irregular schedules due to the low numbers. I was concerned that mid-week may have been a problem with the ferry to Koh Kood but pleased to report that they are, currently, running a full service of 2 ferries per day between the Laem Sok Pier and Ao Salad on Koh Kood.
Ferries depart Laem Sok Pier at 10:45 and 14:20 with return times of 09:00 & 12:00. The current cost is THB.500 per person/per direction.
Our GPS did take us to the old pier which is a bit of a shock, but it is just a few minutes from the new one. Use the Boonsiri co-ordinates to avoid this!
Their facility is good and well organised. Adequate car parking(they also have additional lots) and well organised check in. Reception staff were excellent and spoke good English. I am not certain if the other ferries offer the same service but with the Boonsiri you have door to door service. When you check-in they ask you for your accommodation and on arrival at Ao Salad, passenger pick-up trucks will be waiting to take you. This is the same on the return and both worked perfectly.

There is a good café serving a variety of food and the coffee is not so bad. Restroom facilities are clean.

They supply a people mover to take the passengers out along the long pier. The vessel itself is modern and comfortable with both air-conditioned seating inside and plenty of space to sit outside. Journey time is approx. 1 hour.

Our journey was calm but as it was overcast there was not a lot to see and we eagerly awaited our arrival in Koh Kood!
