    La verdad no esperábamos gran cosa y lo pasamos muy bien, todo un acierto! Tengo que destacar que íbamos en el barco unas 20 personas eso se agradece porque si no estamos masificados,como nos ha pasado con otros tours. En el barco no había ningún español, eran todos de etnia India, la tripulación, y quizás de alguna etnia diferente. la ruta por las islas está muy bien está cerca de Railey me pareció muy completa nuestro guía que no recuerdo el nombre fue súper amable y nos explicó todo súper bien Las zonas donde hicimos Snorkel nos encantaron había muchos peces y disfrutamos mucho del día por la noche a última hora hicimos lo de la bioluminiscencia que también nos encantó. Fuimos solo cuatro personas las que nos tiramos al mar y genial todo repetiríamos sin ningún tipo de duda

    Wonderful tour overall. The guides were friendly, but the lunch portions could’ve been larger. The plankton was magical!

This afternoon sunset tour to the 7 Islands is the best way to see the islands in the national park, go swimming with bioluminescent plankton and enjoy a tasty BBQ. This trip has it all: snorkeling, swimming, relaxing and sightseeing. Watch the sun set on the beach and when it's getting dark you will be able to swim with plankton that magically turns bright blue. It doesn't hurt but can be a tingling sensation as you swim in it. It's a great photo opportunity so be sure to bring a camera! Dinner is served with a BBQ. If you wish to have vegetarian food, please let us know during checkout, so we can prepare accordingly.

FAQs

For dinner you can expect a delicious Thai-style BBQ buffet. You’ll have several (halal) choices like a curry, Pad Thai, stir fried, rice, fish and meat. The food is halal. If you have any specific food allergies, please let us know prior to booking this tour.

Visitors from Railay can join the tour by taking a longtail ferry service (100 THB per shared boat) from Railay East Pier to Ao Nam Mao Pier. You will need to self-arrive to Ao Nam Mao before 13:30. We will drop you off there as well as it is the last stop. If you are staying at Centara Grand Resort, you can take the hotel shuttle boat to Ao Nam Mao Pier, from where we can pick you up. A reservation might be necessary.

The best time to visit the 7 Islands is after the rainy season when the waters are calm. This is usually the case between November - March, but weather conditions may vary. You’ll find clear waters during the hot season in April and May, but make sure to bring sunscreen as it can be very hot!

Yes, it is totally safe. They are minuscule animals and swimming with them feels a bit weird at the start. It can give you a bit of a rash sensation on your skin, but that will be gone the moment you get out of the water. The stunning views of the bright blue colors is absolutely worth it.

Yes, young children (2-3 years) are welcome to join this tour. Please note that it may be difficult for very small children to get in and out of the longtail boat, as well as for elderly persons. Unfortunately, we do not recommend nor accept very young children (0-1 years) to join.

The 7 Islands sunset tour will run during rainy days if the water is calm enough. If that is not the case, we will reschedule the trip for a calmer day or refund you the deposit (if any).

Yes. Cancelling or moving your booking to another date is free up to 24 hours before the tour starts, and anything you have paid is refunded in full. Cancellations made less than 24 hours before the start time are non-refundable, and no-shows are not refunded. If we have to cancel, for example for weather or safety, you can move to another date or take a full refund.

To keep the ride safe, this tour is not suitable for pregnant women. If that could apply to anyone in your group, contact us before booking and we will help you find a better fit.

    Fantastic Hong Islands trip on the speedboat—fast, smooth, and well-organized Rating: 5 / 5 Stars (or your preferred rating) Pros: Speedboat Advantage: Taking the speedboat got us out to the Hong Islands quickly and comfortably, leaving plenty of time on the beach and in the water instead of wasting time in transit. Incredible Scenery: Hong Island, the emerald lagoon, and the surrounding limestone karst islands are stunning. The 360° viewpoint climb is a workout, but the panoramic views at the top are worth every step. Great Tour Crew: The Krabi Sunset Tours team was well-organized, friendly, and kept everything moving smoothly from hotel pickup to drop-off. Beating the Morning Crowds: The schedule worked out great for enjoying the beaches without the heavy peak-morning crowds. Cons: Steep Steps to Viewpoint: The climb to the 360° viewpoint is hot and steep, so proper shoes/sandals (not flimsy flip-flops) are recommended. Summary: A top-notch island tour in Krabi. The speedboat makes the journey effortless, the sights are world-class, and Krabi Sunset Tours delivered a seamless, memorable day. Highly recommended!

  • Henri Baumgärtner

    Outstanding experience. Went on a traditional boat tour to hong island and we ended up with a fantastic guide and only 2 others on our boat. Only thing you could „complain“ about is that there will be other boats from other company’s too and it might get crowded.

  • Jimmy De groof

    We hadden een fantastische 4 eilanden tour gehad. Met een goede gids. Onze kinderen hebben van de speedboat genoten en het eiland hoppen. Alles liep zeer vlot en was prachtig verlopen

  • Wilfred Bouw

    Het was een zeer goed verzorgde excursie, vanaf het oppikken bij het hotel, tot aan de boot tot aan het eten, alles was netjes geregeld.. Absolute topdag gehad en een echte aanrader!

  • Gérard Michaud

    Très bonne organisation, guide efficace. Découverte des îles mais tour limité qui laisse de la place pour le snorkeling. Bon repas.
