Krabi Island Tours
Compared

The 4 Islands tour is Krabi's most classic sea trip, and it's the first pick people recommend if you're short on time or traveling with kids, since every island sits close to Ao Nang with short boat rides that don't slam through waves the way longer tours do. Boats leave in the morning and loop through 4 famous islands in one day. It starts at Chicken Island, where a rock formation shaped like a chicken's head juts out for photos, plus snorkeling over coral and schools of fish. Next comes Koh Tub and Koh Mor, where — if you time it right at low tide — a white sandbar appears connecting the two islands so you can walk across. It wraps up at Koh Poda, with fine white sand and clear water, and a limestone peak standing tall offshore that's become one of the iconic images of Krabi.

From real reviews across several platforms, travelers consistently mention that the guides and boat crew are friendly, happy to help out and take photos, the water is clearer and has more fish than expected, and walking across the mid-sea sandbar is often the highlight of the day. Price-wise, it's the lightest of the four tours, especially the longtail boat option, which is cheaper than the speedboat. Compared with Phi Phi, the 4 Islands tour has a much shorter boat ride and a lower price, but the views aren't as dramatic as Maya Bay.

A few things worth knowing before booking: Koh Poda and its sandbar get very crowded around midday — some days dozens of boats arrive at once, making it hard to find an empty spot for photos — and the sandbar connecting the islands only appears at low tide, so picking the wrong time slot could mean missing the walk. Ask the operator about the tide schedule beforehand. Also, the ฿400 national park fee usually has to be paid in cash at the pier.

If you're staying on the Krabi side, you don't need to cross over to Phuket to catch a boat — speedboat tours to Phi Phi Islands depart directly from piers around Ao Nang, saving a lot of travel time. The standard full-day itinerary crosses over to Phi Phi Leh to see Maya Bay, the white sand beach made famous by the film The Beach, stops at Pileh Lagoon where the water turns emerald green surrounded by limestone cliffs, passes by Viking Cave, stops at Monkey Beach, and on many trips continues to Bamboo Island, where the clear water is great for snorkeling — all with lunch and drinking water included on board. This tour's standout feature is the most dramatic scenery of the four routes, making it ideal for anyone who wants to see the legendary beach at least once.

Based on real reviews on Tripadvisor, this group of tours scores around 4.7 out of 5. What reviewers consistently praise is that the operators manage boat queues well without long waits, guides and crew are friendly and attentive, and the views exceed expectations, especially the snorkeling spots where schools of fish are clearly visible. On the downside, Maya Bay gets extremely crowded, with dozens of boats sometimes arriving at once, making it hard to walk around for photos and limiting time on the beach. Another point is that the Andaman Sea can get choppy some days, and the speedboat pounding through waves can cause seasickness.

Typical prices run around ฿1,200–1,800 per person, not including the ฿400 national park fee for adults, which needs cash ready at the island landing point. Check before booking whether the price already includes this fee. Importantly, swimming is not allowed at Maya Bay — you can only walk along and photograph the beach — and it closes for ecological restoration every year from 1 August–30 September. During that period, tours adjust the route to focus on Pileh Lagoon, Viking Cave, and Bamboo Island instead.

The Hong Island tour is the second most talked-about Krabi sea trip after the 4 Islands tour, and most departures leave Ao Nang in the morning. You can choose either a fast speedboat or a traditional longtail boat, which is cheaper and gives a slower, more relaxed feel. The main highlight is Hong Island itself, with fine white sand and clear blue-green water, followed by the Emerald Lagoon (Hong Lagoon), an enclosed inner sea surrounded by tall limestone cliffs, with still water perfect for kayaking or just floating around. Many itineraries also stop at snorkeling spots to see coral and fish, with lunch and drinking water provided during the day. What sets Hong Island apart from other tours is getting both a calm, enclosed lagoon and a high viewpoint in a single trip.

Another feature that sets this tour apart from other island trips is the 360° viewpoint on Hong Island, which requires climbing a fairly steep staircase and trail to reach a high vantage point over the lagoon and surrounding islands. Those who make it up often say it's worth the sweat, though some reviews warn the path can be slippery and tiring, so wear shoes with good grip. Tripadvisor scores sit around 3.7 out of 5, reflecting that the experience depends quite a bit on the operator and timing — some trips get crowded with limited time at each stop.

Standard prices run around ฿900–1,600 per person depending on boat type and itinerary, not including the roughly ฿300 national park fee for adults, usually paid in cash at the pier or on the island. Ask clearly before booking whether the price already includes this fee, and check whether it's a joined group tour or a private charter, since the number of people per boat affects comfort and time at each stop quite a bit.

If your goal is the clearest water possible and worthwhile coral snorkeling, Koh Rok (Koh Rok Nok-Koh Rok Nai) and Koh Ha are the answer that clear-water lovers rank as Krabi's number one. Both sit within Mu Ko Lanta National Park. Most tours depart Koh Lanta in the morning, riding a speedboat for around an hour or more, stopping at several snorkeling spots where the coral is still in good condition and fish are clearly visible, before landing on Koh Rok for lunch on white sand beaches with water so vividly blue that many say it exceeds expectations. Some itineraries also stop at Koh Ha, which has caves and limestone cliffs worth seeing. What puts Koh Rok ahead of other Krabi tours is the noticeably clearer water and healthier coral reefs.

One important thing to know honestly: the national park closes the islands during monsoon season, roughly mid-May to mid-October each year, to let the ecosystem recover. So if you're visiting in the rainy season, this trip simply isn't available — you can only plan for mid-October through mid-May. That's the biggest limitation compared with the other three tours, which run nearly year-round. Another factor is the long distance — boat rides run around an hour or more each way, so those prone to seasickness should bring medication, and if you're staying on the Ao Nang side you may need to connect by boat/car to Lanta first, so plan travel time accordingly.

Real reviews from those who've been tend to praise the clear water and still-beautiful coral, with guides and crews mostly rated as attentive, and many tours include lunch that gets good feedback. Points of criticism include some trips overbooking guests so people end up sitting exposed to the sun at the bow, some snorkeling gear being old or leaky, and because this is a seasonal tour with fewer visitors than the more popular routes, there aren't enough reviews per operator to draw a reliable average score. It's worth choosing an operator with clear, detailed reviews and asking about equipment condition and passengers per boat before booking.
