Ohotu Wall

When Garuae's tide is wrong, Rotoava's boats slide along to this outer wall and lose nothing worth mourning. The face drops through healthy plate and boulder corals with the Tuamotu signature clarity — 30-meter visibility is an ordinary day — and traffic from the nearby pass spills constantly along it: gray reef and blacktip sharks on patrol, snapper and unicornfish in loose formations, turtles working the ledges, eagle rays gliding the drop. The wall suits unhurried profiles that the passes never allow, so photographers use it to actually compose rather than react. It fills the valuable role of a world-class consolation prize.

その瞬間のために: Ocean-clear water on an easy wall; steady shark and turtle traffic; breathing room between pass adrenaline.

地形: Outer-reef wall and sloping hard-coral terraces facing open ocean

エントリー: The outer-reef wall near Garuae's eastern shoulder; dived as a gentler alternative when the pass window is closed.

危険生物・リスク: Moderate current along the face; open-ocean swell over the reef crest on big days.

保全: Same biosphere, same rules as the passes — hands off, hooks unnecessary, distance kept.

ナイトロックス: ここでは効果的です——このエリアのプロファイルは、ナイトロックスが無減圧潜水時間を有意に延ばせる水深帯にあります（適切なトレーニングを受けていることが前提です）。
