This dive site, known simply as 'the arch', is a geological marvel located in Myanmar's Mergui Archipelago. Divers navigate through a unique natural rock archway, exploring dramatic granite formations and intricate swim-throughs. While no specific history or story beyond its natural formation is provided, its distinct topography makes it a memorable and challenging adventure for experienced divers.
The Arch boasts a rich marine ecosystem, adorned with vibrant soft corals and elegant gorgonian fans. The site is a magnet for large pelagics, including barracuda, trevally, and various reef sharks. Lucky divers may even encounter occasional whale sharks and manta rays. Beyond the big stuff, the site teems with diverse reef fish and intriguing macro life.
This site is best visited during the dry season (October to May) when conditions are typically more stable, though currents remain variable year-round, offering an exciting challenge. Highlights include navigating the iconic arch, exploring the swim-throughs, and encountering large pelagic species. Due to the unpredictable currents and depths up to 22 meters, it is strictly recommended for experienced scuba divers. Freedivers would find the currents too challenging and unpredictable for safe breath-hold diving.
