The beach is crystal clear, and it's less crowded in winter, making it perfect for relaxing by the sea alone. Staying overnight on the island would also be wonderful.
The itinerary is comprehensive, including a whale watching trip with no extra explanations or disturbances, and the safety measures are excellent. It is highly recommended for anyone wanting to experience a boat trip in Okinawa, and even in winter, the waves are not too strong.
