Cambodia is preparing for a busy December 2026 as two major tourism events bring together international runners, cultural enthusiasts and coastal holidaymakers. The 31st Angkor Wat International Half Marathon and the 12th Annual Sea Festival are expected to strengthen the country’s appeal during the peak year-end travel season. Both events combine tourism promotion with community development, environmental awareness and opportunities for local businesses.

Information available as of 15 October 2026 identifies these two celebrations as important highlights of Cambodia’s December tourism calendar.

Angkor Wat International Half Marathon Returns to Siem Reap on 6 December

The 31st Angkor Wat International Half Marathon is scheduled for Sunday, 6 December 2026, at the Angkor Archaeological Park in Siem Reap.

The internationally recognised sporting event attracts runners who want to combine athletic participation with an opportunity to explore Cambodia’s celebrated cultural heritage.

The race follows a relatively flat route through the historic temple landscape, with participants passing several ancient monuments within the UNESCO World Heritage-listed archaeological park.

The event is recognised by the Association of International Marathons and Distance Races, strengthening its international sporting profile.

Beyond promoting Cambodia as a destination for sports tourism, the marathon supports important humanitarian initiatives.

Its charitable objectives include assisting landmine survivors, raising awareness about anti-personnel mines and supporting children’s healthcare.

The Angkor Hospital for Children is among the organisations associated with the event’s charitable activities.

For Siem Reap, the marathon also creates opportunities for hotels, restaurants, transport providers and local tourism operators as runners and accompanying visitors travel to the destination.

Travellers can find additional information through the Angkor Hospital for Children event page.

Cambodia Sea Festival Returns to Preah Sihanouk Province From 18 to 20 December

Cambodia’s 12th Annual Sea Festival is scheduled to take place from 18 to 20 December 2026 in Preah Sihanouk Province.

The three-day celebration will focus on the country’s coastal tourism potential while highlighting marine conservation and sustainable economic development.

The announced theme, Sea Value: Blue Economy Connects Coastal Biodiversity, reflects Cambodia’s growing emphasis on protecting marine resources while developing tourism opportunities.

Prime Minister Hun Manet is expected to attend the opening ceremony.

The festival programme is set to feature beachside musical performances, sporting competitions, cultural activities and exhibitions showcasing locally produced seafood.

Visitors will have opportunities to experience Cambodia’s coastal traditions, regional cuisine and entertainment offerings.

The event is also expected to benefit accommodation providers, restaurants, local traders and businesses operating within the coastal tourism economy.

For Cambodia’s tourism industry, the Sea Festival provides a platform to promote Preah Sihanouk Province beyond its established beach holiday market.

Its environmental theme also highlights the importance of maintaining coastal biodiversity as tourism infrastructure and visitor activity expand.

The event details have been reported by the Cambodian News Agency.

December 29 Public Holiday Could Influence Travel Arrangements

Cambodia will observe the Day of Peace in Cambodia on Tuesday, 29 December 2026.

The national public holiday commemorates the end of the country’s prolonged civil conflict and represents an important occasion in Cambodia’s modern history.

Government offices and some administrative services may close for the holiday.

However, hotels, restaurants and major tourism businesses are generally expected to continue serving visitors.

International travellers should confirm operating hours for public services and make transport arrangements in advance where necessary.

The holiday also provides an opportunity for visitors to understand an important chapter of Cambodia’s national history.

December Events Strengthen Cambodia’s Sports and Coastal Tourism Appeal

The Angkor Wat International Half Marathon and the Sea Festival highlight two different areas of Cambodia’s tourism development.

Siem Reap continues to attract visitors through its historic temples, cultural experiences and internationally recognised sporting events.

Meanwhile, Preah Sihanouk Province offers opportunities for beach tourism, seafood experiences, marine recreation and coastal festivals.

Together, these events can encourage travellers to explore different parts of the country during a single holiday.

The marathon demonstrates how sporting events can support charitable causes and destination promotion, while the Sea Festival places environmental conservation alongside tourism development.

Both celebrations also create opportunities for regional businesses and local communities to benefit from visitor spending.

Cambodia Looks Towards a Promising Year-End Tourism Season

Cambodia’s December 2026 calendar offers visitors a combination of international sport, coastal entertainment and national heritage.

The Angkor Wat International Half Marathon on 6 December and the Sea Festival from 18 to 20 December are positioned to attract travellers with different interests.

With the Day of Peace public holiday following on 29 December, visitors should plan accommodation, transport and sightseeing arrangements carefully.
