I am going to Okinawa main island and Miyakojima for an adventure of sorts. Looking to go for dives in Blue Cave and Miyakojima, and maybe a trek in Iriomote island. I am also thinking of maybe cycling from Naha to Cape Hedo with checkpoint stays along the way, and castle ruins too. Would love to meet up with like-minded travelers. If you drive we can get a car and share the costs.
