Thailand is full of wedding settings that go beyond the familiar resort beach, and two places stand out for couples who want something more memorable than a standard island ceremony. Trang, in the south-west, offers one of the most unusual wedding experiences in the country, while Koh Chang delivers a greener, more laid-back island backdrop for couples who want sea views without the better-known crowds.

Trang is best known for its annual underwater wedding ceremony, a spectacle that has drawn international attention since the mid-1990s and is linked to Guinness World Records as the world’s largest underwater wedding. Couples can register their marriage beneath the Andaman Sea, around eight metres down near islands such as Ko Mook or Ko Kradan, usually in February around Valentine’s Day. For travellers, the appeal is not just the ceremony itself but the setting: clear water, coral reefs, limestone cliffs and a coastline that still feels much quieter than nearby Phuket and Krabi. The Trang Love Festival 2026 took place from 13 to 15 February, but the exact dates can change from year to year, so anyone planning a trip around it should check closer to departure.

Beyond the headline event, Trang has practical advantages for visitors who want a more relaxed Thai beach holiday. The province’s 46 islands provide options for secluded stays, and the mainland is known for lively local food and fishing communities rather than polished resort strip. That makes it a strong choice for couples who want a wedding trip with a sense of place, not just a photo opportunity. According to Tourism Authority of Thailand material, the event also carries a conservation message, with coral reef protection part of its wider identity.

Koh Chang, by contrast, suits couples who want a tropical island wedding with a wilder edge. Thailand’s second-largest island is wrapped in rainforest-covered hills and ringed by beaches, giving it a more untamed feel than the country’s busier wedding hotspots. It is a good fit for travellers who want a ceremony that feels private and natural, with options ranging from barefoot beach vows to yacht weddings, garden settings or traditional Thai blessings.

For visitors, Koh Chang’s appeal lies in the combination of scenery and ease. Resort planners can arrange the essentials, including flowers, photography, food and accommodation, which is useful for destination weddings where guests may be travelling from abroad. The island is also part of a marine national park, so there is plenty to do before and after the ceremony, from waterfall walks to quiet beach time. In a country famous for destination weddings, Trang and Koh Chang offer two very different answers to the same question: do you want romance with a crowd, or romance with a sense of discovery?
