Planning Krabi island hopping – routes, timing and the right boat

The longtail boat is Krabi’s icon: wooden hull, long propeller shaft, loud and charming. For short hops to the Poda group or Railay it is a fine choice. For further destinations it becomes slow, wet and uncomfortable in waves.

Group speedboats are fast and affordable but follow a fixed plan. You share the boat with many strangers and usually arrive when everyone else does. A private speedboat combines speed with freedom: you decide the start time, route and how long you stay, and the captain can react to tides and weather.

Ao Nang is the ideal base because nearly every island group is within reach. Four routes have proven themselves and can be combined depending on your interests.

Two clocks rule your island day: the tides and the timetable of the big tour boats. The Tup sandbar needs low water, the Koh Hong lagoon looks best at higher water, and some lagoons in Phang Nga Bay are only accessible within a certain window.

Most group tours leave Ao Nang mid-morning. Start an hour earlier and you often have the first stops to yourself. Another strategy is the reverse route: go first to where the groups arrive last, and leave before they turn up.

Half-day trips of four to five hours are enough for the Poda group or Railay. For Hong, Phang Nga Bay or a combination of areas, six to eight hours is more relaxed. Phi Phi and Koh Rok only make sense as full-day trips.

A common mistake is cramming too many stops into one day. Better four places with enough time to swim, snorkel and take photos than eight places at a rush.

When choosing an operator, look for safety and transparency: life jackets in the right sizes, an experienced captain, clear information about national park fees and what the price includes. A good boat has shade, fresh water for rinsing off and enough drinking water on board.

The biggest difference, though, is the crew’s knowledge. If they know the tides, they know when the sandbar appears. If they know the area, they know which bay is empty right now. That local knowledge is what turns a boat ride into an experience.

With these points covered, you are ready for almost any island day:
