The original 9 AM meeting time for the four-in-one tour was changed to 10 AM via email, which I acknowledged. However, on the day of the tour, I received a call at 9:35 AM asking why I wasn't at the meeting point, implying I was late. I provided a screenshot of the email as proof. They didn't even acknowledge their mistake regarding the schedule change, simply stating that the times were "about the same." I cannot agree with such a casual approach. Fortunately, I arrived early to have breakfast near the port and made it just in time. The facilities on the boat were very new. After the guided coastal trail walk, climbing to the summit felt very rushed, so half the people on the boat didn't make it to the top. The time allocation was a bit insufficient. The itinerary is excellent and worth visiting Keelung Islet. The weather that day was superb, and the scenery was breathtaking. The guided commentary was also very good, and we clearly saw the spectacular Keelung Sea Trench.
