El Bajon

El Bajon is the Canaries' most famous single dive: a saddle-backed volcanic pinnacle off La Restinga whose twin peaks climb from deep blue to near-snorkel depth. The rock is ringed by life that reserve protection has let grow old — dusky groupers of real size, island groupers, thick schools of amberjack and barracuda wheeling off the towers, morays in every crack. In the warm months something bigger often passes: mobulas, tuna, occasionally a whale shark. Water clarity in the Mar de las Calmas routinely embarrasses the rest of Europe.

その瞬間のために: Twin towers in blue water, large groupers, summer pelagic fly-bys

地形: Twin volcanic towers rising from deep water to within about 8 m of the surface

流れ（カレント）: An open-water pinnacle — current can pick up mid-dive and dives are planned around it.

エントリー: Short boat ride from La Restinga, El Hierro, inside the Mar de las Calmas marine reserve; dived when current allows.

危険生物・リスク: Current and open-water exposure; the summit tempts divers upward while the walls tempt them past plan depth.

許可証＆ルール: Daily boat and diver management applies within the reserve — book through local operators.

保全: Inside the Mar de las Calmas reserve; diving runs through authorized La Restinga centers under reserve rules.
