Trang Underwater Wedding is a legally recognized annual event held every Valentine’s Day, inviting 30-40 couples from across the globe to register their marriage 8 meters inside the Andaman Sea. It’s a Guinness World Record-holding event that has evolved into a high-energy, inclusive celebration and welcomes everyone from Gen-Z adventurers to LGBTQ+ couples.
While the underwater signature is the main event, this wedding festival in Thailand packs in everything from vintage parades to beachside galas, making it one of the most unique ways to kick off a life together.
If you’re in for the most unique Thailand event 2026, plan your Thailand trip to take vows under the water while exploring some of the beautiful sights in the world. Now let’s dive into the details.
Trang Underwater Wedding 2026: Major Highlights
If you're wondering what makes the Trang Underwater Wedding Thailand a Guinness World Record holder, it’s these specific moments. Here are the major highlights of the ceremony:
The Tuk-Tuk Parade
Trang vintage Tuk-Tuk frog wedding parade starts in Trang town (near Trang Chamber of Commerce at 188 Kantang Road) one day before the wedding ceremony. You’ll ride in a Tuk-Tuk Frog, Trang’s iconic vintage taxi. Locals cheer from the sidewalks while you along with dozens of other couples head toward the clock tower in traditional Thai wedding costumes.
Marriage Vows Under The Water
You’ll descend 8 meters to a submerged altar for marriage registration at Emerald Cave Thailand where a registrar waits in scuba gear. Instead of a paper book, you sign a waterproof marriage certificate right on the seabed. It’s one of the surreal things to do in Thailand, surrounded by coral and tropical fish.
If you’re an international couple, you require a formal, separate registration at a local district office (Amphur, Thailand) for your marriage to be legally binding worldwide.
Rot Nam Sang Ritual
Since you can’t pour water underwater, you’ll perform the Rot Nam Sang, a Thai ritual requiring you and your partner to pour multicolored sand over each other's hands. The sand symbolizes a bond that is solid and inseparable. It’s a unique, visual twist on the traditional Thai wedding blessing.
The Koh Kradan Beach Party
After registration of your wedding, come back to the surface to celebrate. The party moves to the white sands of Koh Kradan, which was recently named the best beach in the world. This is the official reception and sunset gala for the newlyweds. Hold a drink and celebrate with a massive beach feast together.
Love In The Middle Of Andaman
For couples who do not want to dive, there's "Love in the Middle of Andaman” so you can take vows on the white sands of Koh Pradan. You can still participate in the parade and post-wedding celebrations along with other couples.
A Global Celebration of Equality
In 2026, the vibe is all about marriage equality and inclusivity, so the energy is high and welcoming for everyone. Following Thailand’s new marriage laws, the festival is a massive, high-energy celebration for all couples including LGBTQ+.
The event actively welcomes international couples from across the globe. The organizers provide translators and help with the logistics for foreign visitors, making it a massive multicultural meetup where love is the only language anyone actually needs.

Trang Underwater Wedding Dates For 2026
Mark your calendar for the Trang Underwater Wedding dates from February 13th to 15th, 2026. The main ceremony takes place on Valentine's Day (Feb 14th), but the festivities kick off a day earlier with a grand parade on February 13th, followed by post-wedding celebrations and receptions on February 15th.
This is also the absolute best time to visit Thailand offering clear skies and crystal-clear waters, perfect for diving and exploring the best spots in Southern Thailand.
Trang Underwater Wedding 2026 Venue
The Trang Underwater Wedding 2026 venues are straight out of a postcard. Here’s what each venue is offering:
The Emerald Cave (Tham Morakot)
It’s often called the crown jewel of the Andaman, and one of the best places to visit in Thailand for honeymoon. To get to the main Trang Underwater Wedding 2026 location, you actually have to swim through an 80-meter long dark sea cave tunnel.
It isn’t as intense as it sounds because once you emerge on the other side, you’re standing in a hidden lagoon with emerald-green water, white sand, and limestone cliffs. This gives the ultimate secret hideaway vibe for a wedding ceremony.
Waen Island
Known for its healthy coral reefs, this is the primary Trang Underwater Wedding 2026 location for the underwater registrations because the visibility is usually top-tier in February. It’s located about 10 kilometers off the coast, and has shallow, crystal-clear water with a huge amount of colorful soft corals.
Since it’s only about 8 meters deep, the sunlight hits the reef perfectly, so you don't need a massive professional lighting rig to get a decent photo of your waterproof marriage certificate.
Siwalai Beach
Located on the peninsula of Koh Mook, Siwalai Beach is also called the Underwater Wedding Beach is a sandbar which feels like you’re walking in the water. It’s the official site for all the marriage registrations on land (for non-diver couples), and the staging area where couples gear up before heading to the dive sites. It’s the best spot for 360-degree wedding photos.
Koh Kradan
Koh Kradan is the face of the Trang Underwater Wedding Festival 2026 and among the must-visit islands in Thailand. It has been recently ranked as one of the best beaches in the world. This is where the "Love in the Middle of the Andaman" beach ceremony happens on the powdery white sand. It’s underdeveloped, quiet, and serves as the primary spot for the sunset gala and the official beachfront reception.
Trang Love Festival 2026: Official 3 Days Schedule
Now, let’s have a look at the full Trang Love Festival 3-day schedule:

Day 2: Trang Underwater Wedding Ceremony (Feb 14th)
This is Valentine’s Day and the main event. You’ll take a boat from Pak Meng Pier to Koh Kradan and the Emerald Cave. Couples descend 8 meters, guided by professional instructors to sign waterproof certificates and perform the sand-pouring ritual, while those who don’t want to dive-in, stay topside for the "Love in the Middle of the Andaman" ceremony on the beach. Once everyone is back on sand, the day ends with a sunset gala and a reception on Pak Meng Beach.
Day 3: Merit and Culture (Feb 15th)
The final day is about experiencing the local culture, officially as married couples. You’ll travel to the Kantang District to visit ancient shrines and the historic wooden train station.

Free Participation (for Selected Couples)
If you’re among the 9-14 selected couples for the ceremony, your underwater or beach vows, the Tuk-Tuk parade, the official reception, and the blessing ceremonies are typically covered by the festival organizers. This may also include your transportation to the dive sites and several of the main celebratory meals.
However, you’ll need to budget for the logistics not covered by the organizers. Based on the current model, here is what you should expect to pay for out of pocket:
