Buchanan's Wall is a spectacular underwater rock wall on the northern side of South Solitary Island, approximately 30 minutes by boat from Coffs Harbour on the NSW North Coast. This vertical drop-off is encrusted with vibrant coral gardens and sea anemones, dropping into deeper water and attracting abundant marine life including green turtles, wobbegong sharks, lionfish, anemonefish, octopus, and moray eels. The wall's overhangs and crevices create a natural aquarium that dazzles snorkellers and divers alike, with crystal-clear sub-tropical waters offering excellent visibility.
