Nusa Dua is an area in the southern part of Bali, Indonesia, known as an enclave of large 5-star resorts. The place name 'Nusa Dua' can be used in two ways: either it can refer to the entire eastern side of the Bukit Peninsula at the southern tip of Bali, or it can refer to the purpose-built, safe and rather sterile tourist enclave (Kawasan Pariwisata, quite literally Tourism District) at the southeast side of this peninsula.

As well as a host of luxury hotels, Nusa Dua is home to the most popular golf course in Bali and the main convention centre on the island. The beaches here are glorious - white sand, deep, long and safe for swimming. The public beach at Geger is the best to head to if you are not staying at Nusa Dua. This is also home to one of the best museums in Bali.
