The islands of Siargao, Phu Quoc, Lombok and Koh Rong were once regarded as remote hideaways visited mainly by adventurous travellers. Although each island has a unique geography and culture, their paths from obscurity to fame share common threads. Government involvement, infrastructure investment, sustainable development strategies and international recognition have propelled these former best‑kept secrets into the mainstream. As their profiles have risen, they have contributed to a broader redefinition of regional tourism in Southeast Asia, illustrating how remote sites can be woven into national development agendas and global travel networks.

Siargao – Surfing capital becoming a cornerstone of Philippine tourism

Siargao Island off Mindanao’s northeast coast has long been famous among surfers for its powerful waves. The Philippine Department of Tourism has described the island as the surfing capital of the Philippines and highlighted its islands, lagoons, waterfalls and caves. The same source notes that Siargao has a dedicated airport with direct flights from Manila, Cebu and Davao, making the island readily accessible. A Bureau of Immigration report explained that a new immigration office in General Luna opened in March 2026 to serve growing visitor numbers, reflecting a commitment to provide convenient services for foreign nationals.

Events and recognition have magnified Siargao’s appeal. The island hosts the annual International Surfing Cup during the July–November season, and travel media rankings have cited it among the world’s best islands. Local authorities promote spots such as Cloud 9 and Sugba Lagoon, diversifying offerings beyond surfing into island‑hopping and kayaking. Environmental campaigns encourage responsible practices and, together with the immigration office, help regulate visitor flows. Siargao is now positioned as a model for balancing adventure tourism with environmental care and community participation.

Beyond surfing, Siargao offers pools, mangrove forests and inland waterfalls that support wildlife. Community‑managed tours have been established to guide visitors through these landscapes while educating them on environmental protection. Local eateries showcase organic produce and seafood, ensuring that tourism benefits local fishers and farmers.

Phu Quoc – Vietnam’s emerging eco‑tourism and marine centre

Phu Quoc, Vietnam’s largest island in the Gulf of Thailand, is being transformed from a quiet fishing community into a high‑quality eco‑tourism and marine tourism centre. Provincial reports describe it as a shining spot on the world tourism map and rank it among the world’s most beautiful islands. Between 2020 and 2025 the island’s economy grew by about 19.6 percent per year, with growth driven largely by trade and services. Its 150 km coastline and diverse ecosystems have attracted more than 6.5 million visitors in the first nine months of 2025 and generated revenue exceeding 31,138 billion VND.

Investment and infrastructure have been pivotal. Hundreds of projects have been licensed, creating thousands of hotel rooms and an international airport and port handling dozens of flights daily. Visitors enjoy diving, fishing and island tours as well as new attractions like a coral park, eco‑resorts, theme parks and an eight‑kilometre cable car. Traditional crafts such as fish sauce making are recognised as cultural heritage. The island has been selected to host APEC 2027 and aims to welcome 15 million visitors by 2030 while adopting digital transformation and marine economy priorities. During Lunar New Year 2026, Phu Quoc greeted about 170,000 visitors, and cultural performances and folk games were organised to enrich the experience. Together, these actions illustrate that Phu Quoc is being reinvented as a comprehensive eco‑tourism hub balancing environmental assets, modern infrastructure and cultural heritage.

Lombok – From overlooked sister to “New Bali” within Indonesia’s tourism strategy

Situated east of Bali, Lombok has long been compared to its famous neighbour but possesses its own identity. Research from Indonesia’s science agency has called Lombok “Bali 30 years ago” and emphasised its rich Sasak culture blending Balinese and Arabic influences. Many of the attractions that draw travellers to Bali, such as volcanic foothills and surf beaches, are also found on Lombok. The same research noted that Sasak traditional villages provide employment and preserve culture, and government programmes encourage Cultural Tourism Villages.

Government plans have pivoted Lombok toward tourism‑led development. The West Nusa Tenggara masterplan observed that Lombok has become a popular destination but faces challenges such as increasing solid waste. To boost the economy, authorities have established the Mandalika Special Economic Zone in south Lombok and built the Pertamina Mandalika International Street Circuit, where a world‑class MotoGP event was hosted in 2022. The province targeted two million visitors that year. Policy incentives and infrastructure projects show how Indonesia aims to diversify tourism away from Bali and position Lombok within its “10 New Balis” strategy. Despite challenges, cultural preservation and planning frameworks remain central to ensuring sustainable growth.

Koh Rong – Cambodia’s coastal jewel embracing sustainable tourism

Koh Rong is an island of about 78 square kilometres located roughly 40 kilometres off Cambodia’s Sihanoukville coast. Government reports describe it as offering beautiful beaches, and provincial authorities are promoting ecotourism sites as part of a strategy to protect ecosystems and generate jobs. The Ministry of Information highlighted efforts to make two areas—Or Bei Choan and the Prek Ta Sok mangrove community—plastic‑free destinations, a policy expected to attract visitors and support local economies. Local authorities support tourism communities to oversee eco‑friendly development.

Regional plans situate Koh Rong within a larger coastal tourism vision. The Multi‑Purpose SEZ portal notes that Cambodia’s coastal provinces contain dozens of islands, and selected islands such as Koh Rong and Koh Rong Sanloem are being jointly developed as an island‑hopping tourism and marine biodiversity belt. The plan aims to transform these islands into premier destinations offering world‑class leisure experiences and recognises strengths such as ecological resources and established hotels while highlighting opportunities for eco‑tourism growth. Koh Rong was chosen to host international delegates during the World‑Bays Club’s 2022 congress and was elevated to city status in 2024, demonstrating government commitment to its development. Sustainable infrastructure projects, including a solar e‑toilet initiative funded by India, support tourism and align with Cambodia’s carbon neutrality goals. Collectively, these actions show how Koh Rong is being transformed into a sustainable coastal destination with strong government backing.

Shared themes and regional significance

Although these islands belong to different nations and possess distinct cultures, several shared themes link their transformation. Strategic government involvement is evident: a local immigration office was opened in Siarga; Vietnam’s central and provincial authorities have collaborated with investors to build infrastructure and plan international events for Phu Quoc; Indonesia established the Mandalika SEZ on Lombok and hosted MotoGP; and Cambodia elevated Koh Rong to city status and promoted eco‑tourism.

Infrastructure investment has transformed accessibility. Airports, ports, cable cars and SEZs have been constructed or upgraded, enabling Siargao, Phu Quoc and Lombok to receive increasing numbers of travellers In Koh Rong, facilities such as island‑hopping transport and sanitation projects are being developed.

Sustainability and cultural preservation connect the islands. Siargao promotes community‑managed tours and environmental stewardship. Phu Quoc balances development with eco‑tourism and recognises intangible heritage such as fish sauce crafts. Lombok addresses waste challenges while supporting cultural villages. Koh Rong advances plastic‑free ecotourism and solar sanitation initiatives.

Lastly, international recognition and events have raised profiles. Siargao’s surfing competitions and travel awards, Phu Quoc’s inclusion on global best‑island lists and its APEC 2027 host role, Lombok’s MotoGP event and Koh Rong’s hosting of world congress visitors all demonstrate growing prominence. Collectively, these islands exemplify Southeast Asia’s shift toward diversified destinations that prioritise environment and culture while leveraging events and infrastructure to compete globally.

Redefining regional tourism through sustainable growth

The transformations of Siargao, Phu Quoc, Lombok, and Koh Rong show that Southeast Asia’s future lies in diversified, sustainable destinations. These islands have moved beyond niche status through targeted government action, infrastructure investment, cultural preservation, and strategic marketing. Their success is measured not solely by visitor numbers but by the balance achieved between economic growth and environmental stewardship. By converting pristine environments into well‑managed tourism hubs, these former secrets are reshaping regional tourism. They serve as models for balancing development with sustainability, celebrating local culture and embracing inclusive growth. In doing so, they invite travellers to engage with authentic experiences while supporting communities and protecting ecosystems.
