Koh Sdach (King Island) is a small but stunning island located off the coast of Koh Kong Province in southwestern Cambodia. This small island, part of an archipelago of 12 islands, lies just a 10-minute boat ride from the mainland and is roughly midway between the towns of Koh Kong and Sihanoukville.
It sits in the Gulf of Thailand, nestled between the mainland and a chain of untouched islands, making it a peaceful getaway surrounded by clear waters and rich marine life.

About Koh Kong Province
Koh Kong is one of Cambodia’s most naturally diverse provinces, known for its tropical rainforests, mangroves, waterfalls, and beautiful beaches. It borders Thailand and is a gateway to both ecotourism and coastal development. Koh Kong is currently attracting attention for its natural beauty and potential for sustainable tourism and investment.

In recent years, Koh Kong Province has seen significant investment in road infrastructure, transforming it from a remote coastal region into a well-connected, accessible destination. The upgrade of National Road No. 48, which connects Koh Kong to Phnom Penh via National Road No. 4, has dramatically improved travel times and opened the province to both domestic and international visitors. The currently operating Dara Sakor Airport, which was officially opened to domestic charter flights in December 2024, currently serves flights primarily involving company staff and government officials, with plans to expand commercial operations as demand grows as well.
How to Get to Koh Sdach
Getting to Koh Sdach is relatively easy, especially for adventurous travelers:
- From Phnom Penh, take a bus or private car to Kiri Sakor District, the nearest coastal access point. (You can go directly to Koh Kong or go along the Sihanoukville Expressway and continue your journey to Koh Kong via Sre Ambel road)
- When you arrive at the Kiri Sakor port, you can catch a local boat or private ferry to Koh Sdach from there. Depending on conditions, the boat ride takes about 10-15 minutes.
**Please note that some eco-resorts or guesthouses can also arrange transfers directly.
