This deep-water passage between coral gardens channels nutrient-rich currents that attract a dazzling array of marine life, including hawksbill and green turtles, manta rays, reef sharks, and over 500 species of tropical fish. The crystal-clear waters (20–30m visibility) and vibrant soft coral formations make it a standout spot in one of the world's largest marine sanctuaries. Often visited as part of a glass-bottom boat tour alongside Turks Reef, Direction Island, and the Phaeton shipwreck, this is a must-do for adventurers seeking remote, pristine reef snorkeling.","intermediate",null,"published",{"name":53,"amplitude":69,"phase":85,"latitude":22,"model":101,"epoch":102},[54,55,56,57,58,59,60,61,62,63,64,65,66,67,68],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[70,71,72,73,74,75,76,77,78,79,80,81,82,83,84],0.00845687427686626,0.009024203393752109,0.14280301090319447,0.030883703515971046,0.30649136928412474,0.0008092646800712506,0.014165610434165326,0.010865401736037584,0.07197766039821246,0.09177023504067872,0.045252057451652235,0.016896320852346984,0.006316454579131491,0.11451685948947772,0.010827558381880731,[86,87,88,89,90,91,92,93,94,95,96,97,98,99,100],275.58514179034296,189.94798573632283,153.77252944103145,347.363269357206,311.65998348971823,129.08499540697858,0.4798345853343066,349.04039979390944,298.893158757493,145.8943337150268,149.5763817696206,129.52602209060836,312.83299466383625,342.76322764465965,353.7734455215119,"EOT20","1992-01-01T00:00:00Z",[104,108,114],{"name":105,"description":106,"severity":107,"season_start":50,"season_end":50},"Tidal currents in the passage","The passage channels water between the outer reef and lagoon, creating strong tidal currents that can be challenging for inexperienced swimmers.","warning",{"name":109,"description":110,"severity":111,"season_start":112,"season_end":113},"Trade wind chop","Trade winds from May to October can create choppy surface conditions on the outer reef.","caution",5,10,{"name":115,"description":116,"severity":111,"season_start":50,"season_end":50},"Open ocean swell exposure","The site is on the outer reef edge, exposed to open ocean swell conditions.",{"directions":118,"parking":119,"facilities":50,"fees":120,"access_method":121},"Western Boat Passage is a remote snorkel site on the outer reef of the southern atoll of the Cocos (Keeling) Islands.
