Giants Castle is Tofo's big manta wall.
Giants Castle is Tofo's big manta wall.
This is a current-sensitive wall dive, so local entry timing and drift guidance matter.
Giants Castle is a classic Tofo wall dive with several manta cleaning stations and a big north-south reef that keeps the route moving. The site rewards a controlled drift along the wall, with room for rays, game fish, and a few macro pauses in the crevices when the team slows down. Plan it as an advanced boat dive with a negative entry and careful gas management, because the site is current-sensitive and the best runs are the ones where everyone stays tidy.
