In this guide, we’ll take you through some of Indonesia’s hidden islands, uncovering their history, cultural significance, architectural highlights, and the unique traditions that make them truly special.
1. Kei Islands – The Last Paradise

History & Origins
The Kei Islands, located in the Maluku province, have a rich history dating back to the era of spice trade routes. These islands were once a crucial part of the Portuguese and Dutch trading networks.

Over time, the islands blended indigenous traditions with colonial influences, creating a unique cultural tapestry.

The Kei Islands are home to the indigenous Kei people, who maintain deep spiritual connections to the sea. The ‘Larvul Ngabal’ customary law governs the social structure and way of life, emphasizing respect for nature and communal harmony. Festivals such as ‘Hawan-Wanan’ celebrate fishing traditions and involve vibrant boat parades and folk music.
