We took a group tour of the northern, central, and southern parts of Okinawa, and also went snorkeling. I found this sunset kayaking tour to be the most worthwhile. Watching the sunset over the sea was truly beautiful, an unforgettable experience. It's the most recommended activity of our 6-day trip. The staff can speak some simple English, and the kayaking instruction is quite straightforward; you can understand it with just gestures. It's simple and fun. The coach also helps take many photos and is very kind and enthusiastic. The coach provides waterproof phone cases, but your pants will get wet, so remember to bring a change of pants.
