The tour starts with 15 minutes of paddle practice on a stretch of river the company describes as wide and slow, almost a lake, then spends an hour among the mangrove and the banyan trees. The guides point out the protected land hermit crabs and the fiddler crabs on the banks, and some of the staff are Okinawan and drop a little Uchinaaguchi into the commentary. All the guides hold water-rescue certification.
Everything you need is lent free, down to a hat and a waterproof phone case, so you only bring clothes you do not mind getting wet. The same base runs boat fishing, and a combined SUP and fishing plan suits a family that wants a full morning in Kadena.
