Plan your island-hopping day
The Krabi 4 Islands are Koh Poda, Chicken Island (Koh Gai), Tup Island and Mor Island, a short boat ride off Ao Nang. Nearly every trip adds Phra Nang Cave Beach on the Railay peninsula, and at low water a pale sandbar called Talay Waek links Tup and Mor.
Start here to see what each stop is like, which choices actually change your day and where each detailed guide picks up. The tide and the sea set the order on the water, so hold the plan loosely.

Before you book
Settle these before comparing itineraries. Between them they decide how the day feels and what it really costs.
Season and tide
November to March usually brings the calmest water on this coast. Within any month, the tide decides whether the Talay Waek sandbar is dry enough to walk.
Read the when-to-visit guideFull cost
The classic shared and private trips leave out the national park fee: THB 200 per adult and THB 100 per child, paid in cash on the day. The 9 Islands tour has it built in.
See prices and park feesBoat and group
A longtail is slower and sits closer to the water, a speedboat shortens the crossings, and a private boat hands the pace to your own group.
Compare every tourWhere the boats stop
Tup Island's sandbar and the beach at Koh Poda anchor most routes. They suit different moods, so it helps to know what each one offers before you choose.

Tup and its neighbour Mor sit either end of a strip of sand that surfaces as the tide drops. The shared speedboat allows about 45 minutes here; whether you can walk across depends on the water level that day.
Best for: the sandbar walk and the view back along the spit

The largest of the four has a long sandy beach, shallow water and a tall limestone stack just offshore. Shared tours stop here for lunch on the sand, with time afterwards to swim and snorkel.
Best for: lunch on the beach, easy swimming and the offshore rock stack

The Chicken Island landmark, snorkelling, what you carry and where you start from all change the experience. Each guide covers one of them in detail.

Koh Gai takes its name from a rock pinnacle shaped like a chicken's head and neck. Most boats pause for photos and snorkel close by rather than landing.
Read guide
Mask, snorkel and life vest come with the classic tours. Visibility and the exact spot shift with current and boat traffic, so count it as a bonus rather than a promise.
Read guide
Swimwear, sun protection, a dry bag and cash for the park fee cover most of it. Storage on board is tight, so travel light.
Read guide
Railay has no road access, so pickup means a meeting at a beach or pier. The shared tours include it; the private boats add a supplement.
Read guideA typical day
This follows the shared speedboat. Longtails visit the same islands in a different order, and captains swap stops around the tide, so read it as an outline rather than a timetable.
See what to pack for the dayHotel pickup starts around 07:30 in Krabi Town, Klong Muang and Tubkaek and around 08:00 in Ao Nang. Everyone boards at Nopparat Thara Pier, and Railay guests join by boat.
About 45 minutes at Tup, including the walk to Mor Island when the tide allows it.
A snorkel stop off Chicken Island, then a Thai lunch box on the beach at Koh Poda.
Around 45 minutes at Phra Nang Cave Beach, then a run of roughly 20 minutes back to the pier. Hotel drop-offs begin from about 14:00.
Worth knowing
The 4 Islands work best as an easy, scenic beach day close to Ao Nang. If reef snorkelling is the main goal, pick a calm day; if you want more islands, look at the Hong Islands or Phi Phi combinations.
Common planning questions
Koh Poda, Chicken Island (Koh Gai), Tup Island and Mor Island. Most tours also stop at Phra Nang Cave Beach on the Railay peninsula, which is on the mainland rather than one of the four.
Only when the tide is low enough and the crew says it is safe. At higher water the sand between Tup and Mor can be partly or fully covered, and no departure can guarantee a dry crossing.
Not on the classic shared or private tours: adults pay THB 200 and children THB 100 in cash on the day. The 9 Islands tour includes the fee, and the Phi Phi combination charges THB 400 per adult.
No. Trips sold as 4 Islands from Koh Lanta visit a different group of islands in the Trang sea. This site covers the islands off Ao Nang and Railay.
The shared speedboat leaves the pier at 09:00 and has guests back at their hotels from about 14:00. The shared longtail gets back later, around 15:30 to 16:00.
Line up boat type, lunch, guide, park fees and return times, then book the trip that fits your group.
