Ko Khrok is a small island near Ko Lan, smaller than Ko Sak, and functions as a snorkelling stop on boat tours rather than somewhere to spend a day.
Getting there
No scheduled boat. Come on a tour that includes it, or charter from Pattaya or Ko Lan.
Worth knowing
Facilities are minimal — bring everything, including water, food and shade. Do not stand on or touch the coral, and carry all rubbish out.
Conditions change with the season; ask the boat operator whether it is suitable before setting out.
