Koh Samui Named World’s Best Island 2026 — Government Pushes Safety and Sustainability

Koh Samui in Surat Thani province has been ranked first on a leading international travel magazine’s list of the world’s best islands for 2026, drawing attention from both foreign and domestic travelers. The island’s international recognition has shone a spotlight on many aspects of tourism development, including infrastructure, resource management, and protection of the local environment.

The award comes as local and national authorities announce policies to accelerate safety measures and sustainable tourism. Provincial and central agencies say it is necessary to control the impacts of rising visitor numbers, such as waste management, drainage systems, freshwater and energy use, and maritime accident prevention. They plan to coordinate agencies from the Tourism Authority of Thailand to municipal and district offices to create integrated plans.

For local businesses, being named the world’s best island opens economic opportunities. Hoteliers, resorts, restaurants, and service providers expect increased revenues during the upcoming high season but must also cope with higher costs related to improving service standards and investing to meet environmental measures. Many see collaboration with communities and funding from both public and private sectors as key to rapid and sustainable adaptation.

Impacts on local communities include both benefits and risks. Positives include income from selling local products, increased service jobs, and higher employment. On the other hand, communities may face higher housing prices and living costs, more crowded public spaces, and social changes that accompany mass tourism. Local authorities therefore stress the importance of citizen participation in shaping development plans and encourage responsible tourist behavior, such as reducing single-use plastics and respecting local traditions.

On transport and infrastructure, agencies have prepared plans to handle increased passenger volumes, including raising ferry frequency, adjusting flight schedules, and upgrading piers, as well as improving the island’s main roads to support internal travel. Discussions are also underway about expanding health services and emergency communications coverage, especially in beach areas that attract many visitors.

While the award is a major marketing opportunity, many stakeholders warn it should not be treated as mere commercial promotion. They urge using this moment as a turning point to establish tourism foundations that prioritize sustainability and the quality of life for residents. Effective management that integrates environmental, economic, and social measures will be crucial to keeping Koh Samui an attractive and sustainable destination long term.
