In the 4 island vs 7 island tour Krabi choice, the difference is mostly the clock. The 4 Island tour is a daytime trip, roughly 09:00–15:00, to Phra Nang Cave Beach and Chicken, Tup and Poda islands. The 7 Island tour does the same core islands plus a few extra snorkel stops, but it runs from around midday into the evening, with sunset on the beach, a BBQ dinner and a swim among glowing plankton. Price is about the same: ฿599–฿1,200 against roughly ฿899–฿1,195 per adult.
Understanding the Tours
Key Differences Between the 4 Island and 7 Island Tours
The 4 islands tour and the 7 islands tour share a route and a national park. Not a mood, though. One's a bright, busy beach day; the other is a slow afternoon that drifts into darkness. And plenty of people are weighing up Phi Phi as well, so here are all three:
| 4 Islands tour | 7 Islands Sunset tour | Phi Phi tour | |
|---|---|---|---|
| Hours | About 09:00–15:00 (7–8 h with transfers) | About 12:00–20:00 (around 8 h) | About 08:00–17:00 (8–10 h) |
| Price (adult) | ฿599–฿1,200 | ฿899–฿1,195 | From ฿1,099 by speedboat |
| Park fee (adult) | Usually ฿200 | Usually ฿200 | ฿400 |
| Signature moment | Walking the Tup sandbar | Plankton swim after sunset | Maya Bay, Pileh Lagoon |
| Meals | Lunch | BBQ dinner (sometimes a snack lunch) | Lunch |
| Boat time | Short hops | Short hops | 45–60 min each way |
What each does best: the 4 Islands tour gets full daylight for snorkeling, plus the midday sandbar. The 7 Islands tour gets golden-hour light, dinner on the sand, bioluminescence. Only doing one? 7 Islands for romance. 4 Islands for kids and snorkeling. Simple as that.
Islands Included in Each Tour
On the 4 islands tour you visit:
- Phra Nang Cave Beach (Railay)
- Chicken Island (Koh Kai)
- Tup Island with Koh Mor
- Poda Island (Koh Poda)
The 7 islands tour does the same core (Chicken, Tup, Mor, Poda) and adds two or three smaller islets or snorkel spots, often with Railay. Which ones exactly depends on the operator, so two “7 Islands” tickets can look totally different. Ask for the itinerary when you book. Annoying, but worth it.
On both tours Poda Island is the special one. Longest beach, the sea stack just offshore, the best sunset spot. No surprise the 7 Islands tour usually ends there for dinner.
Activities and Experiences
Activities Offered on the Tours
Both tours include snorkelling. Conditions are better on the 4 islands tour, though: high sun, clearer water, 30–45 minutes at Chicken Island. The 7 islands tour usually gets in the water in the afternoon, when the light's lower and things can be a bit stirred up.
- Both tours: snorkelling, swimming, the sandbar at low tide, beach time on Poda.
- 4 islands only: more daylight at each stop, and the Princess Cave at Phra Nang is standard.
- 7 islands only: sunset, BBQ dinner, the night plankton swim.
The plankton swim is what people remember. Tiny organisms glow blue-green when you disturb them, so waving your hands underwater leaves trails of light. Moonless nights are best.
Environmental Considerations and Regulations
Both tours run inside Hat Noppharat Thara–Mu Ko Phi Phi National Park and pay into the same fee system. And the damage is real. Anchors, sunscreen and trampling all wreck coral, and in peak season thousands of visitors land on these islands every day.
The rules for tours in national parks:
- Every visitor pays the park fee.
- No standing on, touching or collecting coral and shells.
- No feeding fish or monkeys.
- Boats should use mooring buoys, not anchors, over reefs.
- Sensitive sites can close seasonally; Maya Bay on Phi Phi closes for part of each rainy season to let it recover.
The eco-minded operators brief you on reef etiquette, use buoys, carry rubbish off the islands and hand out reef-safe sunscreen. Ask about that when you book. More on the fee: national park fee.
Logistics and Accessibility
Departure Points for the Tours
Both tours leave from the same spots, Nopparat Thara Pier and Ao Nang Beach, and Railay Beach guests get picked up by boat. From Krabi Town it's about 30 minutes to Ao Nang, and hotel transfers run around ฿100 per person extra. Songthaews and taxis get you to Ao Nang too, and longtails from Ao Nang Beach go to Railay. See the starting point guide.
Private Longtail Boat Options
A private longtail boat works for either. You get your own schedule, no crowd, and the freedom to mash the best of both together, like the 4 Islands in the morning and then a sunset on Poda. Honestly, that's my favourite version. Private longtails start around ฿4,050 per boat for a small group. Outside late December and January they're easy to get; book a day or two ahead or sort one at Ao Nang Beach’s longtail counter. Details on private boat tours.
Cost and Booking
Comparing Tour Prices
| Tour | Price range (adult) | Park fee |
|---|---|---|
| 4 Islands by longtail | ฿599–฿1,000 | Usually ฿200 |
| 4 Islands by speedboat | ฿749–฿1,200 | Usually ฿200 |
| 7 Islands Sunset with BBQ and plankton | ฿899–฿1,195 | Usually ฿200 |
| Phi Phi and 4 Island tour from Krabi (early bird speedboat) | ฿2,299–฿2,395 | ฿400 + ฿200 |
The price factors are the same for both: boat type, where you book, hotel zone, season. Klook is convenient, and refundable too. Booking direct with Ao Nang operators is usually cheaper. The price guide breaks it all down.
Traveler Reviews and Recommendations
Reviews for both are strong. 4 Islands people praise the snorkeling and the sandbar. 7 Islands people rave about the sunset and the plankton, and now and then grumble about long afternoon hours or a sunset that got clouded out. Listings on Klook and Ao Nang agency sites mostly score 4.6–4.9 out of 5.
What we'd do:
- First time in Krabi, with kids, or keen on snorkeling? 4 Islands.
- Couple, love sunsets, want something memorable? 7 Islands.
- Only one day and must see Maya Bay? Phi Phi, or the Phi Phi + 4 Islands combo.
- Four or more people? A private longtail beats all of them.
