Tourism is generally focused on the coastal areas of Goa, with decreased tourist activity inland. In 2004, there were more than two million tourists reported to have visited Goa, 400,000 of whom were from abroad.

Goa has two main tourist seasons that is winter and summer. In the winter time, tourists from abroad (mainly Europe) come to Goa to enjoy the splendid climate. In the summertime (which, in Goa, is the rainy season), tourists from across India come to spend the holidays.

With the rule of the Portuguese for over 450 years and the consequential influence of Portuguese culture, Goa presents a somewhat different picture to the foreign visitor than other parts of the country. The state of Goa is famous for its excellent beaches, churches, and temples. The Bom Jesus Cathedral, Fort Aguada and a new a wax museum on Indian history, culture and heritage in Old Goa are other tourism destinations.

Historic sites and neighbourhoods: Goa has two World Heritage Sites: the Bom Jesus Basilica and a few designated convents. The Basilica holds the mortal remains of St. Francis Xavier, regarded by many Catholics as the patron saint of Goa (the patron of the Archdiocese of Goa is actually the Blessed Joseph Vaz). Once every twelve years, the body is taken down for veneration and for public viewing. The last such event was conducted in 2004. The Velhas Conquistas regions are also known for its Goa-Portuguese style architecture. There are many forts in Goa such as Tiracol, Chapora, Corjuem, Aguada, Gaspar Dias and Cabo de Rama.

In many parts of Goa, mansions constructed in the Indo-Portuguese style architecture still stand, though in some villages, most of them are in a dilapidated condition. Fontainhas in Panaji has been declared a cultural quarter, showcasing the life, architecture and culture of Goa. Some influences from the Portuguese era are visible in some of Goa's temples, notably the Mangueshi Temple and the Mahalasa Temple, although after 1961, many of these were demolished and reconstructed in the indigenous Indian style.

Museums and Science Centre: Goa also has a few museums, the two important ones being Goa State Museum and the Naval Aviation Museum. The Aviation museum is the only one of its kind in the whole of India. Also, a place not well known to tourists is the Goa Science Center, which is located in Panjim. The National Institute of Oceanography (NIO) is also located in Goa at Dona Paula.
