Giant's Castle
深度范围指从潜点顶部到通常最大深度；"建议认证等级"是运营商通常要求的主流机构等级，并非法律规定。水流和能见度每天都会变化，请将这里的所有信息视为规划参考范围。
Giant's Castle is Tofo's deep den: a long ridge in the 21-to-33-meter band where the coast's heavyweight animals are most reliably met. Smalleye stingrays, among the largest whiptail rays in the ocean and seen here more often than nearly anywhere, cruise the sand line; mantas track the ridge on passage between stations; loggerhead turtles and big morays hold the ledges. Winter dives run to a soundtrack of humpback song. Bottom time is short, the water is often green with the plankton that feeds the megafauna, and encounters obey no schedule: the standard Tofo bargain, at its deepest.
您此行的高光时刻: Smalleye stingray territory; deep-passage mantas; humpback song in winter
地形地貌: Deep reef ridge with ledges and drop-offs over sand at 30-plus meters
水流: Deep and exposed; drift-style diving when the along-shore current runs.
入水前须知
危险因素: Depth is the defining hazard; watch no-deco time and gas from the first minute.
保育: Ray and manta identification shots (ventral patterns) are welcomed by local researchers, taken from distance, without flash barrages.
高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
