Amanwana
Amanwana occupies an enviable location off the coast of Sumbawa, east of Bali, and is known for its premier diving opportunities. Here, avid divers and snorkelers have access to the Sea Wall and Turtle Street, home to hawksbill and green turtles, moray eels, lobsters and black-tip and white-tip reef sharks. (If you prefer to view your marine life from above, cruising and fishing excursions are readily available.) Luxurious tents await, each with a coral-stone deck, air conditioning, a sitting area, a king-size bed and hardwood floors. Choose an ocean-view tent or one closer to the lush jungle.
Take the river excursion that includes swimming in emerald waters under gentle waterfalls. If you're really adventurous (and physically fit), hike to the bat cave.
