An honest comparison of Krabi's two classic island days: what each one does best, where the crowds are, which suits kids, and how to do both in the right order.

It is your second evening in Ao Nang, the sunset is fading behind the islands, and you have room for exactly one boat trip this week. The two names everyone throws at you are Hong Islands or 4 Islands, and they sound almost the same. They are not.
I have sent friends and family on both trips many times, and the feedback is always clear in the end. One is the easy, cheerful beach day. The other is the one people still talk about at dinner. Here is how to pick the right one for you, and how to fit in both if you can.
4 Islands is the classic beach-hopping day just south of Ao Nang, built around Phra Nang Cave Beach and the Tub sandbar, while Hong Islands is a scenery day north of Ao Nang, built around an enclosed emerald lagoon. Both include hotel pickup, lunch, fruit, soft drinks, snorkel gear, life jackets, an English speaking guide and accident insurance.
The 4 Islands tour stops at Phra Nang Beach on the Railay peninsula with its famous Princess Cave, Tub Island, Chicken Island and Poda Island. It runs every day from 08:30 to 15:30. The stops are close together, so you spend more time on sand and less time on the boat.
The Hong Islands tour heads to a cluster of limestone islands to the north. The centrepiece is the Hong lagoon, a pool of green water hidden inside a ring of cliffs. You also get the sheltered beach on Ko Hong and snorkelling around smaller islands such as Pak Bia.
In one sentence: 4 Islands is about beaches and the fun of walking between islands, Hong is about cliffs, a lagoon and a slower, quieter feel.
For pure scenery, Hong wins for most people. The Hong lagoon is the single most striking sight on either trip, and the beach on Ko Hong is enclosed by cliffs on three sides, which makes it feel private even when boats are pulled up on the sand.

The lagoon is reached through a gap in the rock, and how you see it depends on the tide. At higher water the boat may slip inside, at lower water you may look in from the entrance or wade and swim. Either way, the moment the cliffs close around you is what people remember.
That said, Phra Nang Cave Beach on the 4 Islands tour is no runner-up. It sits at the tip of the Railay peninsula, under tall cliffs with climbers hanging off them. It often appears on lists of the best beaches in Thailand, and the Princess Cave at the end of the beach is a local shrine as well as a sight.

If you have seen one Krabi limestone beach, you might think you have seen them all. The lagoon is different: it is the one sight on these trips that you cannot get anywhere else close to Ao Nang. That is why I put Hong first for scenery.
Speedboat guests on the Hong trip also get the 360 degree viewpoint, a climb of 419 steps to 239 meters. It is hot and steep, but the view over the islands is the best panorama on either tour.
4 Islands is usually the busier of the two. Phra Nang Beach and the Tub sandbar are among the most visited spots in Krabi, because they are close to Ao Nang and reached by many boats every day. In the high season from roughly December to March, expect plenty of company.

The crowd is cheerful rather than miserable. Families splash in the shallows, couples take photos on the sandbar, and longtails line up along the shore. But if you picture an empty beach, Phra Nang at midday is not it.
Timing helps a little. The tours follow similar schedules, so the busiest moments come when several boats arrive at once. A good guide will shuffle the order of stops to avoid the worst of it, but on a group tour you cannot control this fully.
Hong is popular too, especially at the lagoon. But the islands are spread out, the beach on Ko Hong is a little calmer, and stops like Pak Bia feel much quieter. On the longtail version, Daeng Island is small and undeveloped, which is exactly its appeal.
A few ways to cut the crowd feeling on either trip:
Both trips offer easy, beginner friendly snorkelling rather than serious reef diving. Chicken Island and Poda on the 4 Islands route are known for coral and fish, while the beach on Ko Hong has fish right in the shallows, so you barely need to swim out.

On 4 Islands, the snorkel stop near Chicken Island is the best of the day for most guests. The water is clear in the dry season, and the reef has colourful fish and coral. Poda adds more reef and a long sandy beach for a rest afterwards.
On Hong, the beach is a natural bowl with a narrow opening to the sea. Put your face in the water and schools of striped fish surround you. Pak Bia offers more coral and shells, and the smaller islands on the route have quieter water with fewer swimmers.
My honest view: if snorkelling is your top priority, neither of these is the best trip in the region. They are good for first timers and kids. Serious snorkellers should look at a longer day trip further out. For a casual swim with fish, both work, and the 4 Islands reef stop slightly edges it.
Weak swimmers should keep the life jacket on the whole time. It makes floating effortless, and you will see just as many fish from the surface. Do not stand on coral or touch anything, both for the reef and for your feet.
One tip for both: visibility drops after heavy rain or rough seas. In the wetter months, treat the snorkelling as a bonus and focus on the scenery.
Here is how the four tours line up, using only what the tour pages list.
| Tour | From (adult) | Key stops | Best for |
|---|---|---|---|
| 4 Islands by longtail | ฿1290 | Phra Nang Cave Beach, Tub sandbar, Chicken Island, Poda | Budget travellers, first boat trip, families |
| 4 Islands by speedboat | ฿1490 | Same four stops, faster and drier | Families with small kids, people who dislike engine noise |
| Hong Islands by longtail | ฿1490 | Hong lagoon, Ko Hong beach, Pak Bia, Daeng Island | Couples, slow travellers, scenery lovers |
| Hong Islands by speedboat | ฿1690 | Hong lagoon, Pelay Beach, 360 degree viewpoint, Pak Bia, Lao Lading | Active travellers, photographers, short stays |
The 4 Islands tours list child prices of ฿990 by longtail and ฿1190 by speedboat for ages 3 to 11, with under-threes free. For the Hong tours, check the child prices on each tour page. Remember that the national park fee is paid on top on all of these trips.
If the boat type is your main question, the comparison of the 4 Islands longtail and speedboat options goes into spray, noise and comfort in detail.
4 Islands is the better family trip, mainly because of the Tub sandbar and the short hops between stops. Children love walking across the sea between two islands at low tide, and nothing on the Hong trip matches that moment for kids.

The sandbar between Tub and Chicken Island appears only at low tide. The crew plans the stop around the tide, but on some days it is narrow or under water. Tell kids it is a maybe, not a promise, and nobody is disappointed.
The 4 Islands route is also compact. Less time on the boat means less noise, less boredom and fewer cases of seasickness. Phra Nang Beach has shade under the cliffs, which helps by late morning.
Hong can still work for families with older children. Teenagers often prefer it, and the viewpoint on the speedboat version is a good challenge for active kids. But for under-tens, I would start with 4 Islands.
One rule applies to every boat trip here: the tour pages say people with heart or other serious medical conditions, and pregnant women, are not allowed to join. If someone in your family is unsure, check before booking.
Yes, do both if you have four or more full days in Krabi. Book 4 Islands first as an easy warm-up, then Hong a few days later, picking the calmest morning in the forecast. This order works for three reasons.

First, 4 Islands tells you how your group handles a day at sea. If someone gets seasick or burnt, you can adjust before the Hong trip, for example by switching to a speedboat or a longtail.
Second, Hong is the bigger visual payoff, so it is worth saving for the best weather. Keeping it for later in your stay gives you room to move the date if the sea turns rough.
Third, doing 4 Islands first gives you context. Once you have seen Phra Nang and Chicken Island, the lagoon at Hong feels like a real step up, not a repeat.
Before the Hong day, read the Hong Islands tour guide with lagoon and beach details, so you know what each stop offers and can plan your swim and photo time.
Leave at least one rest day between them. Back to back boat days in tropical sun wear people out, and you will enjoy the second trip more after a lazy day by the pool.
If you only have time for one, choose like this: families and first timers take 4 Islands, couples and scenery lovers take Hong. The 4 Islands longtail suits tight budgets and first boat trips, and the Hong speedboat suits short stays and anyone who wants the viewpoint.
Booking takes a few minutes. Both trips include hotel pickup, and the exact pickup time is sent after booking. Choose a tour page, send the booking request or a WhatsApp message, and the team confirms the details.
Here are the four tour pages: the 4 Islands tour by longtail, the 4 Islands tour by speedboat, the Hong Islands tour by longtail and the Hong Islands tour by speedboat.
What to pack for either day:
Plans can change on the day. The operators may adjust the route because of weather, and that is for your safety. Book early in your stay, keep a spare day, and you will most likely get both trips in good conditions.
No. The Hong lagoon is in a different group of islands north of Ao Nang and is only on the Hong Islands tours. The 4 Islands tour stays south, around Railay and Poda.
Only at low tide. The tour times try to match the tide, but on some days the sandbar is narrow or covered by water. You can still swim and relax at Tub Island when it is under water.
Hong Islands usually means more time on the water, because the islands are further from Ao Nang and spread out. The 4 Islands stops are close together. The speedboat option shortens the rides on both trips.
Both trips go to national park areas and the fee is paid separately. The 4 Islands tour page lists 400 baht per adult and 200 baht per child. Check the Hong tour page for its fee before you go.
Not on these group tours, as each one is a full day with its own route. The better plan is two separate days with a rest day in between.
Both can be affected by wind and waves from about May to October. The 4 Islands route is shorter, so it is often the easier choice in unsettled weeks. Keep your dates flexible either way.
No, masks and life jackets are included on all four tours. Bring your own mask only if you have a favourite one that fits well.
