The Cyclops Reef gets its name from the way it looks from above—a lone, circular pillar stands inside the reef’s rocky walls. After you rescue Aryll from the Forsaken Fortress, enemy Warships and wall-mounted cannons appear here.
Sea Platform
Sail up to the single Sea Platform and climb its ladder. Defeat the enemies on top to reveal a chest containing a minor reward.
Treasure Chart #21
Bomb all the Warships and wall-mounted cannons to reveal a chest on the reef’s only “eye.” Go to the narrow opening in the wall and walk up the slope and across the top of wall to its highest point. If needed, play the “Wind’s Requiem” to direct the wind, and then use the Deku Leaf to float to the chest, which contains Treasure Chart #21.
Light Ring Chart (via Treasure Chart #21)
Find and open Treasure Chart #21 (found at this island) to pull a chest from the Great Sea near the Cyclops Reef. The chest contains the Light Ring Chart.
