Geological origins
The Gili Islands sit just off the northwest coast of Lombok in the Indonesian archipelago. Geologically, they are very young. The three small islands (Trawangan, Meno, and Air) formed within the past few thousand years from coral reef growth and volcanic sediment in the shallow waters off Lombok's shore. Unlike the dramatic volcanic landscapes of nearby Lombok or Bali, the Gilis are flat and sandy, with their highest point on Trawangan reaching only about 30 metres above sea level.
The waters surrounding the islands are part of the Coral Triangle, the global epicentre of marine biodiversity. The reefs here host hundreds of species of fish and coral, and the warm, clear water creates ideal conditions for the marine ecosystem that draws visitors today.
Early human history
Before tourism arrived, the Gili Islands were home to small Sasak communities who migrated from Lombok. The Sasak are the indigenous people of Lombok and make up the vast majority of the island's population. They are predominantly Muslim, and their culture blends Islamic traditions with older animist beliefs and Balinese Hindu influences from centuries of regional trade.
The original settlers on the Gilis were mostly fishermen and coconut farmers. Life was simple: small wooden houses, subsistence fishing, coconut harvesting, and occasional trade with Lombok. There were no motor vehicles, no electricity, and no regular contact with the outside world beyond the fishing boats crossing to and from the mainland.
The name "Gili"
The word "Gili" is often assumed by visitors to be a specific name, but it simply means "small island" in Sasak. So "Gili Trawangan" literally means "Trawangan Island." This is why you will find many other "Gilis" scattered around Lombok and West Nusa Tenggara, though the three Gilis off the northwest coast are by far the most famous. Gili Trawangan gets its name from the Sasak word "terowongan" meaning "tunnel," referring to a Japanese-built tunnel on the island dating from World War II.
World War II
During the Japanese occupation of Indonesia in the early 1940s, Japanese forces built a small military installation on Gili Trawangan, including a tunnel that still exists today. The tunnel is located on the south side of the island and is a reminder of the wartime period. The islands were otherwise largely unaffected by the war, with the local communities continuing their traditional way of life.
Rise of tourism in the 1980s
Tourism on the Gili Islands began in earnest in the 1980s. A few adventurous backpackers discovered the islands while travelling through Lombok and word started to spread. The first basic bungalow operations appeared, usually run by local families who would host travellers in simple wooden huts for a few dollars a night. There was no running water, limited electricity, and no real infrastructure, but that was part of the appeal.
Through the 1990s, more travellers came. Bali was becoming increasingly developed and commercial, and the Gilis offered an alternative that felt authentically quiet and unspoiled. The islands started to develop a reputation in the backpacker community as a place to escape to, and small dive shops began opening to cater to travellers interested in the coral reefs.
The diving boom
In the late 1990s and early 2000s, the Gili Islands became known as one of the best places in Southeast Asia to learn to dive. The warm, calm, clear waters with abundant marine life and affordable prices attracted travellers from all over the world. Dive shops proliferated on Trawangan first, then Meno and Air. Blue Marlin Dive, one of the first operations on the island, set standards that others followed, and the quality of PADI training became genuinely world-class.
The diving boom brought more infrastructure: restaurants, bars, guesthouses, and shops all sprung up to serve the growing visitor numbers. By the mid-2000s, Gili Trawangan had developed a reputation as a party island, with beachfront bars hosting live music and backpackers filling the dance floors into the early hours.
The no-motor-vehicles rule
One of the defining characteristics of the Gili Islands is the ban on motor vehicles. This rule is not a recent tourist gimmick. It reflects the original way of life on the islands, where the only transport was walking, horse-drawn cidomo carts, and small fishing boats. When tourism developed, the local community chose to maintain the ban, recognising that the absence of cars and motorbikes was one of the main reasons visitors loved the islands. Today, the only wheels you will see are bicycles, cidomo carts, and the occasional goods trolley.
The 2018 Lombok earthquakes
In July and August 2018, a series of powerful earthquakes struck Lombok, causing severe damage on the main island and significant impact on the Gilis. The earthquakes killed over 500 people across the region and displaced hundreds of thousands. On the Gilis, buildings collapsed, jetties were damaged, and visitors had to be evacuated. Tourism on the islands came to a complete halt for months as repairs and reconstruction began.
The islands recovered through late 2018 and into 2019, supported by the Indonesian government, international aid, and the tireless work of local people rebuilding their businesses. Many hotels and restaurants reopened within a year, and by the start of 2020 tourism had largely returned to normal. The rebuilding effort also led to improvements in some infrastructure, though the earthquakes remain a painful memory for the Sasak communities who call the islands home.
COVID-19 and beyond
The coronavirus pandemic in 2020 and 2021 brought tourism to another complete halt. The Gilis, which depend almost entirely on visitor income, were hit hard. Many hotels closed, dive shops suspended operations, and restaurants struggled to survive. Local people returned to fishing and farming to get by. The community showed remarkable resilience, and as Indonesia gradually reopened to international travel in 2022, visitors began to return.
Today, the Gili Islands are once again thriving as a travel destination, with visitors coming from Europe, Australia, Asia, and beyond. Each island has developed its own distinct character: Trawangan remains the liveliest with nightlife and diving, Meno focuses on romance and tranquility, and Air sits comfortably in the middle with its yoga scene, food culture, and strong local community.
Looking forward
The Gili Islands face ongoing challenges: climate change and rising sea levels, coral reef degradation, plastic waste, over-tourism in peak season, and balancing development with preservation. Local organisations like Gili Eco Trust work on reef restoration, waste management, and cidomo welfare. The community and visitors alike share a responsibility to protect these fragile islands for future generations.
The Gilis are proof that a small place can welcome the world while keeping its character intact. The no-cars rule, the Sasak culture, the reefs, and the simple pace of life are all still here, waiting for anyone willing to slow down and appreciate them.
