Tour was ok. The...

Doa_F, Apr 2026

Tour was ok. The advertising on planktons are wrong, so if you are booking a tour to see planktons glow at night, you will be very disappointed. They are so tiny and so little in quantity that you wonder if the tiny glitter is a hallucination. The part that really annoyed us though was the pick up and drop off experience. The person who picked us up drove like he was racing with the traffic. So fast and it was very dangerous because we were seated on the back of a van with no seatbelts and an open back. So, in any case of a traffic accident, we'd be flying out of the back of the vehicle, no door to stop us. We told him to slow down, then explained to the tour organiser that this was not ok (dangerous). He dismissed it and said, it's fine. After the tour, we had to wait for 40 minutes to get dropped back off at our accomodation. Then, the driver drove past our accomodation, so we did a 25 minute tour until he found our accomodation. It was apparently because we didn't stay in a big hotel.

Beautiful experience on our honeymoon

Caitlin_K, Apr 2026

Beautiful tour to amazing scenic locations, the tour guides went above and beyond to make our honeymoon special and even gave us a little chocolate cake to celebrate after our dinner on the beach 🩷 thank you so much! Would recommend to others.

Must do tour

Jessica_A, Oct 2025

Great afternoon! Highly recommend this bc after about an hour at Hong Island, the early tours left abs we had all the places to ourselves. Sunset was rained out but otherwise a perfect afternoon and evening. Crew was great.

False advertising at its best! No glow in the dark planktons

Salman_M, Aug 2025

We originally booked a long boat, for a smaller group setting. Ended up on a speedboat with 25+ other people as they had nothing else available. Dinner was a precooked meal that was set up by the crew on a smaller island.. underwhelming, not very hygienic I felt since we had left on the boat at 12 and were served food at 5pm. For the Planktons we were taken near the area, stayed on the boat while the crew threw buckets of water on the boat floor to show us the planktons which were about 0.5 seconds of small light and then faded. For the sunset they took us to an island where we had to wade through hard rocky water, then walk on the extremely rocky, dangerous path to get to the actual beach. This was unsafe many people tripped. On the return, boat stopped at the edge of the beach. Which had ditches and since it was 8pm it was dark, not able to see where you’re going in the water and people fell. Overall very disappointing experience. Do not recommend to anyone I’m sure there are better ones out there.

Response from Host, Sep 2025

Thank you for sharing your experience. We’re genuinely sorry to hear that the tour did not meet your expectations, and we appreciate the opportunity to respond. While we regret the change from longtail to speedboat, this was a necessary adjustment due to operational constraints on the day. We understand this impacted your sense of intimacy, and we’re working to improve how such changes are communicated and managed. Regarding the dinner setup, our crew prepares meals with care and follows food safety protocols, though we acknowledge that the timing and presentation may not have felt ideal. We’re reviewing this aspect to ensure it better reflects the quality we strive for. The plankton experience is one of nature’s more subtle wonders, and visibility can vary depending on moonlight, tide, and weather. While we aim to offer immersive viewing, safety regulations sometimes require guests to remain on board. We’re exploring alternative ways to enhance this part of the tour. As for the sunset stop, we chose that location for its panoramic views, but we take your safety concerns seriously. We’re now reassessing the terrain and lighting conditions to ensure safer access and clearer guidance for all guests. We’re truly sorry that the experience didn’t resonate with you. Our team is passionate about creating memorable journeys, and while this one fell short for you, we hope you’ll find future adventures that better suit your expectations. Warm regards,

Incredible!

MARINA_W, Nov 2024

I am very very pleased and happy with this whole experience. We had multiple options of activities we could choose from when we stopped for a few hours at each island. The staff were very friendly :) The only thing I would let the travel company know and the individual booking is to make sure there are not any additional fees included. (Please make park fee clear to the customer before the event) I was not made aware about the national park fee which made the begging a little more complicated. However, I managed to grab the cash quickly from my hotel but note: (double check all fees are included in price and if not reach out to agency to double check any additional fees not clearly stated on main page) Otherwise, I would HIGHLY recommend.

Good for the price

Helio_S, Dec 2025

Good tour in general with good quality-price ratio. Very friendly guide and places visited with time to appreciate. Dinner is reasonable.

The trip has us well...

Isabell_S, Nov 2025

We really enjoyed the trip. Pickup as well as transfers and boat trip went smoothly. The crew was very friendly. On Hong Island we had almost 2h stay, at the other stops it was a little less. Here we would recommend, if necessary, to make the stays a little more even. The glowing plankton we saw, looked beautiful.

Tour okay, transportation disastrous

Christian_S, Sep 2025

The tour was very nice and fun therefore 3 stars but the transport was a disaster Already at noon we had to get into vehicles back and forth and everyone was pushed in.. In the evening we were simply left in darkness with the reason it does not drive a car into the hotel... after several complaints we had to huddle back into a vehicle and the driver dropped us off on the road and not in front of the hotel... Such a thing for the price is unacceptable and we would book another tour next time
