Regions to know
To frame your trip by what you have time for and what you're after.
Bali
Ubud, Uluwatu, Canggu, Sidemen, Lovina, Amed
The tourist heart — Hindu majority in a Muslim country, distinct culture. South (Canggu, Seminyak, Uluwatu) is the developed coast. Center (Ubud, Sidemen) is rice-paddy and culture. North (Lovina, Munduk) is volcanic and untouristed.
Java
Jakarta, Yogyakarta, Borobudur, Mt Bromo, Ijen
The country's main island (60% of the population). Skip Jakarta unless transiting. Yogyakarta as cultural base for the temples; the volcanoes (Bromo, Ijen) on the east. 5–7 days adds the country's depth.
Lombok & Gili
Gili Islands, Senggigi, Mt Rinjani, Kuta Lombok
Bali's quieter neighbor — Muslim majority, less developed, equally beautiful. Mt Rinjani is a 2-day climb (3,726m, second-highest volcano in Indonesia). Kuta Lombok for surf without the crowd.
Flores & Komodo
Labuan Bajo, Komodo NP, Padar, Pink Beach, Wae Rebo
Eastern, drier, more rugged — Komodo dragons, the Pink Beach, the Manggarai villages of the interior. 3–4 days minimum, ideally a multi-day boat trip from Labuan Bajo.
Sumatra
Bukit Lawang (orangutans), Lake Toba, Padang surf
The 6th-largest island — wild jungle, orangutans in Bukit Lawang, the world's largest volcanic crater lake (Lake Toba), and the Mentawai surf islands. Second-trip destination; demands time.
Raja Ampat & Papua
Raja Ampat karst archipelago, Sorong, Wayag
World's most biodiverse marine area — the diving bucket list. €1,500+ per week on a liveaboard or land-based lodge. Hard to get to (multiple flights, then boats); worth the effort for divers.
