Frequently asked questions
Is the snorkeling actually good?
Managed expectations: this is the Gulf near a major city, not the Similans. Koh Krok and Koh Sak have live shallow coral patches with reef fish, and on a clear November–February day visibility of 5–10 metres is realistic. It is a fun, easy snorkel — not a world-class one, and we would rather tell you that up front.
What are Koh Sak and Koh Krok like?
Koh Sak is a small horseshoe-shaped island just north of Koh Larn with two sandy crescents; Koh Krok is a 28-rai islet with a single sand pocket and coral on its east side. Neither has the crowds — or the facilities — of Koh Larn, which is why tours combine all three.
Can non-swimmers join?
Yes — life vests are mandatory at snorkel stops anyway, the water at the stops is shallow, and you can always stay on the boat or beach. Tell the crew and they will keep an eye out.
What about sea conditions and seasickness?
Crossings are short (the islands are 7–10 km offshore) but speedboats slap in chop. November to February is calmest; in the May–October monsoon, morning departures are smoother. If you are sensitive, take a tablet 30 minutes before boarding.
What should I bring?
Swimwear worn under clothes, towel, reef-safe sunscreen, a hat, cash for chairs and drinks, and a dry bag for phones. Underwater cameras rent at the pier, but a phone in a waterproof pouch does the job for shallow reefs.
