The short answer

Worth it if everyone is fit, can swim or float in a life jacket and the sea is calm. It is a long, hot day with wet landings, so older travellers and small children may prefer a beach day.

Why it matters
Why Ko Rok and Ko Haa snorkelling day is worth your time
The islands south of Lanta are why many divers and snorkellers come. Ko Haa and Ko Rok have clear water, swim-throughs and abundant fish, and they are far more beautiful and varied than the near-shore reefs off the beach. Part of the area lies in Mu Ko Lanta National Park, so conservation rules apply: do not touch coral, do not feed fish and do not take shells.
For families, the trip is also the clearest example of how Lanta works by season. Operators run it only in the calmer months, and the park closes its smaller islands from 16 May to 31 October. Treat the date and the sea state, not the brochure, as the guide.

Plan your visit
How to experience it
Most operators sell Ko Haa and Ko Rok as one combined day, leaving in the morning and returning in the afternoon. Wikivoyage describes Ko Haa as one of the best sites for snorkellers and divers in the area, with swim-throughs, and Ko Rok as two islands, Ko Rok Nai and Ko Rok Nok, about 47 km south of Lanta, with very dense fish. Ask your hotel to book a trip with life jackets, a clear safety briefing and a small group.
Bring a hat, sunscreen, a rash vest, a dry bag, water and your own snack or vegetarian food, since lunch on boat days is commonly seafood-based. Ask the operator in advance whether a vegetarian lunch can be provided and keep expectations modest. Jellyfish are mentioned in Wikivoyage mainly from January to April, so ask your guide about the conditions.
Go only on calm days. If the sea looks rough in the morning, postpone and reschedule.
