Thai couples tie the knot in sky-high ceremonies on Valentine's Day

Four thrill-seeking couples took to the skies and climbed the large rock in Prachinburi province in the Thailand's east.

The traditional wedding dress and suit was shunned for casual clothes and a harness as the lovebirds, including Nitiphong Jittahong and new wife Rattanaporn Supha, took in the stunning view as they said "I do" in the annual event.

Another set of Thai couples, meanwhile, took their vows deep below the surface, donning scuba tanks in ceremonies held 10m underwater.

Four pairings, including Parinyatit Kantarak and Piyaratwadee Sawasdee, plunged into the Andaman Sea in Trang, south Thailand, to tie the knot.

Brides wore white headdresses and flowers as the newlyweds temporarily removed regulators from their mouths to seal the deal with an underwater kiss.
