The site sits adjacent to a boat channel marked by a channel beacon, so snorkelers should stay within the reef zone. Entry is via steep steps from a cliff-top carpark onto the beach, then a short walk across the sand. The reef is home to colourful sponges, unique molluscs such as the ornate Sagaminopteron ornatum, and offers good snorkelling when conditions are calm — wind and swell can stir up sand and reduce visibility quickly.","intermediate",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.004344884681714959,0.009016588356209325,0.1670224017224663,0.015668064517080006,0.05276376721334385,0.004153335096975204,0.0035806646954730467,0.0049324789908584575,0.014494932010060921,0.12104319735054954,0.051483869293471644,0.024595735404365035,0.012354865708086967,0.04239998416343347,0.002435548521707881,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],70.9343022017847,223.60201344708764,180.9320126717471,33.16640944736978,56.40049940384358,153.15948037088856,26.48467480732177,236.80405480762528,110.10658865551687,174.91095702764179,171.92958290674443,171.85514431737317,320.440593208585,58.98118840218396,266.28952383493436,"EOT20","1992-01-01T00:00:00Z",[110,114,118,121,124,127,130,133,136,141],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Boat traffic channel","Boat traffic in the adjacent channel — do not snorkel beyond the channel marker at the end of the reef.","warning",{"name":115,"description":116,"severity":117,"season_start":56,"season_end":56},"Sharp slippery reef","The shallow limestone reef is sharp and slippery.
