Western hippies and sun lovers gave Goa international recognition almost fifty years ago; it's been a tourism destination for Indians for quite a bit longer than that. Goa's numerous beaches are everything that they're professed to be, miles of beautiful sand, and water that stays warm even in winter. There are enough beaches to ensure relative privacy, as well as spectacular beachfront hotels and resorts that can provide any service you may require.
There are lush forests and plantations; vivid "bazaars' and events; as well as unique local handicrafts and souvenirs. From the 3rd century BC onwards, Goa was ruled by various Hindu dynasties. Despite that, Goa and its people seem to have been influenced more by the Portuguese that came afterwards. The Portuguese arrived hear in the early 16th century and were not eased out ( by the Indian government) till 1961.
The architecture, customs, lifestyle, and people are all still primarily influenced by the departed occupants, in stark contrast to the conservative social mores of the rest of India. Obvious examples are the facts that Goa boasts by far the most (per resident) bars in India, and is also home to the oldest nude beaches in India.
Although exploring the beaches and many other attractions can easily keep you busy throughout your visit here, Goa is probably one of the best places in India to catch up on any relaxation you may need.
