This is the most enjoyable memory of this trip. I was worried that the trekking might be too difficult and hesitated, wondering if I really needed to pay this much for a simple trek. However, the difficulty was just right, and putting all other reasons aside, I came to admit that it was a trek I absolutely had to do. There wasn't a single thing to fault, from the fresh air and clear sky to the lush vegetation, and I had a truly enjoyable time with Miu, who served as our guide. I think it was an even better experience because Iriomote Island remains untouched by human hands. I highly recommend it if you visit Iriomote Island.
