Indonesia's 17,000 islands span a distance wider than the continental United States, from Sumatra's orangutan forests in the west to the glaciated peaks of Papua in the east — with Bali's Hindu temples, Java's ancient stupas, Sulawesi's highland ritual culture, and Lombok's volcanic coastline in between. Tracking which islands and regions you've explored reveals just how vast and varied this archipelago truly is. Your progress is saved automatically — no account needed.
Top cities and UNESCO World Heritage Sites in Indonesia.
The most visited island in the Indonesian archipelago draws millions with its Hindu temples, emerald rice terraces, surf beaches, and a spiritual atmosphere unlike anywhere else in Southeast Asia. From the clifftop Tanah Lot sea temple to the cremation ceremonies of Ubud, Bali rewards visitors who venture beyond its famous beach resorts into living village culture.
Bali's cultural and artistic heartland sits among terraced river valleys in the island's cool uplands, its central market and palace flanked by galleries, woodcarving workshops, and dance performance venues. The surrounding countryside — Tegallalang's rice terraces, the Sacred Monkey Forest, and Campuhan Ridge Walk — makes Ubud a destination in its own right, separate from the beach resorts of the south.
Java's royal city remains the epicentre of Javanese art and learning, home to the sultan's kraton palace complex, the ancient shadow-puppet (wayang) tradition, and some of the finest batik workshops in the country. Positioned between the twin UNESCO sites of Borobudur (45 minutes west) and Prambanan (17 kilometres east), it is the natural base for exploring Indonesia's most important ancient monuments.
The sprawling capital of 34 million inhabitants combines Dutch colonial heritage in the old Kota district, world-class museums, and a booming restaurant and nightlife scene built on wealth from one of Southeast Asia's largest economies. The chaotic street-food stalls of Glodok's Chinatown, the hip cafés of Kemang, and the extraordinary collection of the National Museum represent Jakarta's contradictions at their most compelling.
Bali's quieter eastern neighbour offers pristine beaches on its southern Kuta coast, the forested caldera of Mount Rinjani (Indonesia's second-highest active volcano, at 3,726 metres) for serious trekkers, and a Sasak culture distinct from Bali's Hindu traditions. The island has emerged as a standalone destination rather than a Bali overflow, particularly since road infrastructure improvements have opened up the south coast's untouched bays.
This small fishing port on Flores' western tip has transformed into the gateway for Komodo National Park, putting visitors within easy reach of the islands where Komodo dragons roam wild beaches beside pristine coral reefs. Sunset cruises from the harbour, liveaboard diving expeditions, and the pink-sand beach of Komodo Island have elevated Labuan Bajo into one of eastern Indonesia's prime destinations.
Scientists have identified the seas around these four West Papua islands as the most biodiverse marine ecosystem on earth, home to over 1,500 fish species and 700 coral species in waters of extraordinary clarity. Reached by a short flight to Sorong followed by a ferry crossing, Raja Ampat rewards the journey with manta ray cleaning stations, pygmy seahorses, and jungle-cloaked karst islands rising from turquoise shallows.
The three vehicle-free Gili islands off Lombok's northwest coast — Trawangan, Meno, and Air — offer white-sand beaches and turquoise shallows at different price points and social registers. Gili Trawangan draws a lively backpacker crowd; Gili Meno is the honeymoon island; Gili Air splits the difference, with reliable turtle-sighting snorkel spots just metres from shore on all three.
Bali's largest offshore island became an Instagram phenomenon driven by the iconic view of Kelingking Beach — a T-rex-shaped sea cliff plunging to turquoise water — and reliable manta ray encounters at underwater cleaning stations. Reachable in 45 minutes by fast boat from Sanur, the island's rugged roads and dramatic scenery feel worlds apart from mainland Bali.
The legendary home of the world's largest living lizard rewards visitors with surreal scenes of Komodo dragons draped on dusty hillsides or gathered near water buffalo, all within a savannah-and-mangrove landscape that feels primeval. The surrounding Coral Triangle waters attract manta rays, dugong, and schooling hammerhead sharks, making Komodo as compelling below the waterline as above it.
Rising from the vast Sea of Sand caldera in East Java's Tengger massif, Bromo's smoking crater is one of Asia's most photographed volcanoes, best experienced at dawn from Penanjakan viewpoint as light breaks over the caldera rim. The approach on horseback across the flat volcanic plain, followed by a steep staircase to the crater lip, is one of Indonesia's great sunrise experiences.
Bali's most sophisticated beach strip runs from the boutique hotels and design restaurants of Seminyak through the hip surf cafés of Canggu, where digital nomads and professional surfers share the same beach breaks. The sunset scene at Ku De Ta and the vibrant nightlife of Canggu's Batu Bolong district make this Bali's most stylish — and most expensive — coastal address.
Perched at 768 metres on a volcanic plateau, the so-called 'Paris of Java' built under Dutch colonial rule is now a college city famous for its factory-outlet fashion stores, art deco architecture, and cool-climate café culture. The surrounding volcanoes — Tangkuban Perahu's walk-in crater and the hot springs of Ciater — are easy half-day excursions from the city centre.
The Trans-Flores Highway rewards drivers with a succession of volcanoes, traditional ikat-weaving villages, and the extraordinary tri-coloured crater lakes of Kelimutu, whose waters shift between turquoise, green, and black due to volcanic mineral chemistry. Portuguese missionaries shaped the island's character in the 16th century, leaving a legacy of Catholicism unusual in predominantly Muslim Indonesia.
The Toraja highlands of South Sulawesi host one of the world's most elaborate death-ritual cultures — multi-day funeral ceremonies involve buffalo sacrifices, cliff-face tomb galleries, and tau-tau wooden effigies standing guard over the deceased. The surrounding countryside is spectacularly beautiful, with traditional tongkonan boat-roofed longhouses set among rice paddies beneath limestone karst formations.
Indonesia's second city and East Java's commercial hub retains a rough-edged port-city character, with the Dutch colonial architecture of Kota Lama, the Arab Quarter of Ampel, and Chinese-Indonesian street food in Chinatown sitting alongside one of the country's busiest container ports. Surabaya is the logical base for climbing Mount Bromo and visiting the Ijen volcano's ethereal blue-flame sulfur crater.
The caldera lake of Toba — 100 kilometres long on North Sumatra's highland plateau, formed by the largest volcanic eruption in the past 25 million years — contains Samosir Island, where Batak Toba communities maintain traditional longhouse architecture and intricate woodcarving. The cooler highland air, boat trips between villages, and proximity to Bukit Lawang's orangutan forest make Lake Toba one of Sumatra's most rewarding regions.
The 'forgotten island' has emerged as one of Southeast Asia's most compelling off-beat destinations, combining traditional animist megalithic culture — stone tombs, clan houses, spectacular ikat weaving — with internationally recognised surf breaks and some of the archipelago's most undeveloped beaches. Pasola, a ritual cavalry battle fought in February and March at four traditional sites, is one of Indonesia's most viscerally spectacular festivals.
This string of fishing villages along Bali's northeast coast offers a quieter alternative to the island's busier south, with black-sand beaches, traditional salt-farming operations using ancient methods, and beginner-friendly diving at the Liberty shipwreck at Tulamben — a World War II US Army cargo vessel resting in just 10 metres of water, its hull blanketed in corals and schooling fish.
The thriving capital of South Sulawesi has long been the archipelago's most important eastern trading port, its Makassarese and Bugis seafaring heritage visible in the traditional perahu schooners still moored at Fort Rotterdam's harbour. The city is the gateway for flights to Toraja country and the diving of the Spermonde Archipelago, with its own fish-market restaurants serving sublime grilled seafood along the waterfront.
Most visitors to Indonesia land in Bali — and many never leave. That's not a criticism; the island genuinely rewards extended exploration, from the surf breaks and sunset clubs of Seminyak to the artists' studios and rice terrace walks around Ubud, from the dramatic clifftop temples of Tanah Lot and Uluwatu to the quieter pleasures of Amed's black-sand coast and the offshore drama of Nusa Penida's Kelingking Beach. But Bali is a single island in an archipelago of 17,000, and the traveller who pushes east or west quickly discovers an entirely different country beneath.
Java holds the great monuments: Borobudur, the world's largest Buddhist temple, rising in the mist above the Kedu Plain; Prambanan's soaring Hindu towers just down the road from Yogyakarta's living kraton culture; and the volcanic drama of Mount Bromo, whose smoking caldera at sunrise remains one of Asia's great spectacles. Lombok delivers a Bali of quieter temperament, with its Sasak Muslim traditions, the white-sand bays of the south coast, and Mount Rinjani's full-day crater rim trek for those who want to earn their views. Further east, Flores offers the Trans-Flores Highway road trip through ikat-weaving villages and the tri-coloured crater lakes of Kelimutu, ending at Labuan Bajo as the gateway to Komodo's primeval islands.
Beyond even these well-trodden routes, Sulawesi's Toraja highlands host one of the world's most extraordinary living cultures — multi-day funeral ceremonies with buffalo sacrifices and cliff-face tomb galleries — while Raja Ampat's West Papua waters hold the planet's most biodiverse marine ecosystem, explored by liveaboard divers who describe it as the dive of a lifetime. Sumba's animist megalithic villages, Banda's nutmeg-scented colonial forts, and the orangutan forests of Gunung Leuser in North Sumatra represent the breadth of what this archipelago contains.
