- Go for a walk over the island. You can see the native cassava gardens, great views of the other islands and the Blue Lagoon, as well as get a sense of the difference between the windward and the leeward sides of the island. Take water with you, it can get hot.- Go snokeling in the Blue Lagoon. It has been declared a fish sanctuary and has great fish and some great coral. If you are lucky you can spot sea-horses in the grass, extremely rare fish, or a sea snake obviously give the snake it's space. - Go scuba diving and/or get certified. The Dive shop on Nanuya serves most of the upper the Yasawa chain. The instructors are both extremely knowledgeable and great people. There is also a vast array of great dives just a short boat ride away. The rental gear is also well-maintained and reasonably priced.
