Not all areas of the island offer shuttle service. Because we were staying quite far away, outside the designated area, we rode our scooters to the nearest landmark where shuttles were available before boarding the vehicle. It took another 40 minutes to reach our destination. The guides were very professional; two guides took excellent care of our group of five. The ride was thrilling but actually very safe. You can tip the guides to film the trip; the video was excellent and professional – definitely worth trying!
This tour mainly consists of snorkeling, hiking, and kayaking. The hike involves climbing a very steep and rough path, making it quite challenging, but the scenery at the end is truly spectacular. The guide takes photos for you, which makes for a great memento. I recommend bringing sneakers. It's tough, but I highly recommend climbing.
I checked out of the hotel and left my luggage there, wanting to enjoy the limited time before my evening flight. I was able to enjoy myself to the very end without being burdened by my belongings, and the luggage handover process was smooth and reassuring.
Even though the flight was delayed, they still managed to complete the pick-up and drop-off. That's fantastic!
