The Magdalen Islands split their underwater offering across two distinct sub-areas: Cap-aux-Meules and Entry Island. Dive sites feature reef and kelp forest environments, best explored from shore by intermediate divers. Snorkelling accounts for the larger share of sites. The marine life leans invertebrate-heavy, with Sea Raven and Feather Star observed consistently across sites, and Sponge common throughout. Water is cold for most of the year, warming noticeably from mid-summer into early autumn.

The dive sites listed for the Magdalen Islands are rated at intermediate skill level, so complete beginners may find them challenging. Cold water temperatures for much of the year add to the demands on divers. Snorkelling sites are more numerous and accessible, making them a better starting point for less experienced visitors.
Cap-aux-Meules holds the larger share of sites, while Entry Island offers a smaller, more concentrated selection. Both sub-areas contribute to the overall mix of reef and kelp forest environments that defines diving in the Magdalen Islands. Shore entry is available, as seen at Neils Harbour, which spans a wide depth range from very shallow to quite deep.
Yes, shore entry is documented at sites in the Magdalen Islands, with Neils Harbour being a named example. This removes the need for a boat for at least some dives, though visitors should check local conditions before entering, as exposed coasts can be affected by swell and current.
