City-states are rare in the present day—and none are quite like Singapore. In the 20th century, the Southeast Asian nation hurtled itself into the modern world, and it continues to expand its state-of-the-art transportation system and build its edgy skyline. Yet Singapore’s urban plan wisely maintained its intimate neighborhoods, many with streets lined with colorful shophouses (a type of building unique to parts of Asia, with businesses located on their ground floors and residences above). Add the city’s mix of ethnic groups—mainly Malays, Chinese and Indians—and you get a vibrant cultural scene that attracts a cosmopolitan, international community. Singapore’s food scene—which is arguably the world’s most dynamic and runs the gamut from beloved street hawkers to Michelin-starred venues—would merit a trip alone, as would its never-ending shopping options. But the city is also packed with world-class museums, many designed by celebrated architects, and it hosts many major international events, such as the Formula One Grand Prix. Yet only about half of the 720-square-kilometer (278-square-mile) island is developed, which leaves plenty of room for parks and open spaces such as the Bukit Timah Nature Reserve, where an old-growth forest still thrives.

Indonesia’s second-largest city and Java’s capital, Surabaya is known as the City of Heroes thanks to the important role it played in capturing international attention during the country’s revolution in the 1940s. And that independent spirit is still palpable among the metropolis’s internationally diverse population of nearly three million people. Surabaya is home to Indonesia’s only synagogue as well as the largest mosque in East Java. And colonial-era buildings sit just a short stroll from glitzy new shopping centers. Visitors have much to experience, whether taking in the extensive artifacts in the Museum Mpu Tantular, seeing where Indonesia’s clove cigarettes got their beginnings at the House of Sampoerna or venturing into the city’s green lung with a boat ride through the mangrove forests of Wonorejo. You’ll feel transported to a Middle Eastern bazaar at the Pasar Ampel, where the vendors hawk spices, sticky sweet dates and imported carpets. And a visit to Kenjeran Beach, right in the city, offers the chance to spot fishermen showcasing their fresh catch or take in views of one of Indonesia’s longest bridges. Obviously, deciding where to spend your time will be your main conundrum in Surabaya.

Probolinggo is a pretty port town on the north coast of East Java that’s home to the ethnic minority Tengger people. The city garners mainly tourist attention as a jumping-off point for visiting Mount Bromo. One of Indonesia’s most spectacular volcanoes, Bromo is best viewed at sunrise but makes a strong impression any time of the day. While the top has blown off, the 2,329-meter-high (7,641-foot) peak contains a cone that’s still active. And views of the surrounding volcanoes from here are just as thrilling. If you opt to stick around Probolinggo, a town of roughly 217,000 people, you’ll be pleasantly surprised. There are none of the stifling crowds and pollution of Jakarta here. A pedicab tour is a fun way to get around to see the city’s Chinese temple, pleasant city square, churches and museum. But the main sites are just as easily visited on foot. There are beautiful beaches, temples, waterfalls and bamboo forests to see in and around Probolinggo. And just seven kilometers (four miles) from town at Bentar Indah Beach, you can go for a swim or stroll along the white sand. Before leaving, shop for a typical batik from the region to take home as a souvenir.

Located on Bali’s north shore, Celukan Bawang is gateway to beautiful white- and black-sand beaches, coral reefs ideal for snorkeling and the Pura Ulun Danu Bratan Hindu-Buddhist temple complex.

Indonesia is made up of more than 13,000 islands, but even with all that competition, Bali manages to stand out. Beautiful temples and shrines of all sizes are spread across the island, tucked down narrow alleyways, hidden within the jungle or serenely presiding over scenic locations, like the dramatic Pura Tanah Lot atop a rock formation just off Bali’s western coast. Bali is well known for its arts—traditional music and dance, painting, wood and stone carvings, silver jewelry and ikat and batik textiles. The island’s artistic center is the village of Ubud, and its art markets and boutiques carry beautiful Balinese pieces to take home. When it comes to dining, whether you’re craving a burrito or satay, you can find a restaurant that serves it. Don’t leave the island, however, without sampling Balinese cuisine. Local cooking, which reflects Chinese and Indian influences, uses blends of aromatic spices to season grilled meats (though not beef—Bali is an island of Hindu culture in mostly Muslim Indonesia), fresh seafood, rice and vegetables with delicious results.

One of more than 17,000 islands that make up the Republic of Indonesia, Komodo Island is most famous for its resident Komodo Dragons. The remnant of a once widespread ancient order of monitor lizards, this giant reptile often measures up to 11 feet in length and can weigh more than 300 pounds. Komodo Island is volcanic in origin, with dramatic landscapes of craggy mountains, deep canyons, savannahs and rain forests. Sample shore excursions: Komodo Island Trek.

Tanjung Priok is your gateway to Jakarta, Indonesia’s largest city and exotic capital. Visit The National Museum of Indonesia chronicling sixteen centuries of history; explore Indonesian culture at Taman Mini Indonesia Indah; wander the streets of Old Town and learn about Dutch colonial architecture; tour Masjid Istiqlal (Independence Mosque), the largest mosque in Southeast Asia; and shop for treasures in one of the city’s excellent shopping malls.
