What does one do when they visit the beautiful Pacific island of Okinawa? Hitting the beach is probably on the top of most visitors’ lists. For me, this would not be an option as my recent trip to the island was a short one. I love going to the beach but because I only had one day to hit as much as possible, I went snorkeling in one of the jewels of the island: Blue Cave, a sea grotto that promises stunning waters illuminated in bright blue.
