I've been to Okinawa several times, and my first island hopping trip started near Naha. Tokashiki Island is definitely worth a visit, and the KKDAY package with boat and shuttle service is very convenient. My son and I didn't snorkel, but just hanging out on the beach was plenty. The nearby guesthouses also rent swimming rings, masks, life jackets, and more—everything you need. Walking down the beach to the large rocky area, I was pleasantly surprised to see hermit crabs.
