    The sunset we saw after landing on the “Phantom Island” was absolutely stunning, and we had a truly fulfilling time. There are no age restrictions, and you can participate without bringing anything, so it’s very convenient. If I had to mention one thing, the footing was a bit unstable when boarding and disembarking the boat, so I felt it would have been helpful if there had been a bit more advance warning about that.

    They said it was okay even for beginners, but there were some waves, so it was hard to keep my balance. I managed to stay standing, but I didn’t really have the chance to enjoy the view. The sunset itself was beautiful, so I wish I could have gone on a day when the waves were a little calmer.

    It was nice that they took us to the best spots for seeing mangroves, but there were so many people that it felt a bit rushed. The complimentary photos were a nice touch, but the image quality was just average. Overall, it felt like a casual experience that was worth the price—neither great nor bad.

    The guide's explanation of the constellations was very easy to understand, and I was completely drawn into the world of the night sky. The included transportation made me feel safe traveling at night. However, the sky was a bit cloudy at times, so it was a shame we couldn't see all the stars. Still, it was a very fulfilling experience.

    I took part in a stargazing tour. We were blessed with good weather that day, and I was able to capture a sky full of stars—including the Southern Cross—with my camera. It was a magnificent night sky where every shot turned out beautifully. However, the space to set up a tripod was a bit limited, so it would have been perfect if there had been a little more room.

    The guide took us to the best spots, and we were able to enjoy stand-up paddleboarding amidst the stunning scenery. The guide was very courteous, and the photos we received made for a great keepsake. The shuttle service was also a big help.
