Dive Site: Arche's Plateau

About Arche's Plateau

Arche's Plateau is a renowned dive site located within Madagascar's Radama Archipelago, a region celebrated for its pristine underwater environment and vibrant marine ecosystems. This area, known for its extensive hard coral reefs, remains relatively untouched, offering divers a chance to explore a thriving ecosystem far from more populated dive spots. The topography of the Radama Archipelago, where Arche's Plateau is situated, is diverse, featuring dramatic underwater structures including various drop-offs and colorful coral gardens. The site offers both shallow and deeper dive opportunities, allowing exploration of its intricate features. The waters here are rich with marine life year-round, including massive schools of fusiliers, surgeonfish, batfish, and trevallies, alongside green and hawksbill turtles, wrasse, and humphead parrotfish. Encounters with larger pelagics such as manta rays, mobula, eagle rays, and various shark species like leopard, grey, and whitetip sharks are common. During the season from June to September, humpback whales are present for mating, and from mid-October to mid-December, whale sharks and more manta rays are attracted by plankton blooms. Diving at Arche's Plateau typically involves boat access, and liveaboards often include this site in their itineraries. The currents are generally mild or absent on most sites within the Radama Archipelago, contributing to a relaxed diving experience with good visibility for most of the year. This makes the site accessible for a range of certification levels.
