The main island of Singapore is shaped like a flattened diamond, 42 km (26 miles) east to west and 23 km (14 miles) north to south. Near the northern peak is the causeway leading to West Malaysia—Kuala Lumpur is less than four hours away by car. It is at the southern foot where you will find most of the city-state’s action, with its gleaming office towers, working docks, and futuristic "supertrees," which are solar-powered and serve as vertical gardens. Offshore are Sentosa and over 60 smaller islands, most uninhabited, that serve as bases for oil refining or as playgrounds and beach escapes from the city. To the east is Changi International Airport, connected to the city by metro, bus, and a tree-lined parkway. Of the island's total land area, more than half is built up, with the balance made up of parkland, farmland, plantations, swamp areas, and rain forest. Well-paved roads connect all parts of the island, and Singapore city has an excellent, and constantly expanding, public transportation system. The heart of Singapore's history and its modern wealth are in and around the Central Business District. The area includes the skyscrapers in the Central Business District, the 19th-century Raffles Hotel, the convention centers of Marina Square, on up to the top of Ft. Canning. Although most of old Singapore has been knocked down to make way for the modern city, most colonial landmarks have been preserved in the CBD, including early-19th-century buildings designed by the Irish architect George Coleman.

The island of Belitung is large, measuring roughly 4,800 square kilometer (1850 square miles). Along with neighbouring Bangka and the many other surrounding small islands this is not just an archipelago, but a substantial province of Indonesia. Belitung used to have many tin mines, but today the island is better known for its nature. The most distinct features of Belitung’s many beaches are the fascinating granite rock formations along the shallow shores. These rocks can reach the size of houses and lie in bold contrast to the white sand. Swimming and snorkeling in the crystal clear waters reveals healthy corals and hundreds of fish.

Semarang is one of the oldest cities in Indonesia, situated on Java's north coast between the shore of the Java Sea and a small ridge of mountains. Ceded to the Dutch West India Company in 1677 by King Amangkurat I in payment of his debts, it became their headquarters and the seat of the Dutch governor of the northeast provinces. Semarang's usefulness as a port waned due to the gradual silting up of the harbor; by the 19th century, Surabaya had eclipsed Semarang as Java's premier port. With a population of over one million, a third of whom are thought to be of Chinese extraction, Semarang is the largest city in Central Java and its administrative capital. The city consists of two parts: the coastal lowland where most of the commercial activities are found; and the hilly residential area. Although more a business center than a city for tourists, Semarang serves as a popular gateway to the mountainous interior of Central Java and to fabled Borobudur.

Probolinggo is a beautiful and enchanting city on the north coast of East Java, Indonesia. It is located on one of the major highways across Java, has a harbour filled with fishing vessels and is surrounded on the landward side by the Probolinggo Regency, but is not part of the regency. Probolinggo is home to the Javanese, Maduranese, Pendalungan (descents of Java and Maduranese) and Tenggerese, who still practice their centuries-old customs and traditions. Probolinggo is bordered by the imposing Mount Semeru, Bromo and Argopuro mountain group, and lined with lovely beaches to the north. Probolinggo's volcanic, mineral-rich soil is highly fertile. The mountains surrounding Probolinggo City abound with lush, tropical foliage, spectacular panoramic vistas, and points of natural interests, history and culture. The motto of the city is 'Bestari', which is an acronym of bersih (cleanliness), sehat (healthy), tertib (orderly), aman (safe), rapi (neat), and indah (beautiful).
