Nusa Penida is the largest and most exotic of the 3 Nusa islands, thanks to its collection of unique Hindu temples and picturesque natural features of cliff formations and lagoons. More recently, the island became best known as the new sanctuary of the once-endangered Bali starling (which is originally an endemic species from the forested region of West Bali National Park) following a highly successful captive breeding programme. Nusa Penida measures over 200 sq km – significantly larger than the popular Nusa Lembongan and its easily accessible sister island, Nusa Ceningan. Lesser-travelled by visitors compared to the other 2, Nusa Penida has a very limited number of hotels and tourist features. Nevertheless, what it lacks in infrastructure, it makes up for with its unspoiled natural beauty and rare cultural highlights.
