This magical underwater world sits within the Adelaide International Bird Sanctuary National Park and Adelaide Dolphin Sanctuary, offering a uniquely serene drift-snorkelling experience. The calm, shallow waters reveal a bustling nursery ecosystem—crabs scuttling among the roots, prawns darting through the shallows, and rays gliding over the silty bottom. It's less about colourful coral and more about immersing yourself in a living, breathing tidal forest.","beginner",null,"published",{"name":20,"amplitude":36,"phase":52,"latitude":13,"model":68,"epoch":69},[21,22,23,24,25,26,27,28,29,30,31,32,33,34,35],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[37,38,39,40,41,42,43,44,45,46,47,48,49,50,51],0.030682803813481423,0.014387730773339236,0.25165829451915434,0.12220418281100098,0.5462653192741428,0.02444364073058643,0.0018899044912530103,0.015349604263511838,0.03453659098047733,0.1672362028968482,0.07414412036302388,0.03854755292807723,0.01043715664672968,0.4960895421002746,0.03846877241342577,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],243.34925911587328,280.1041335582407,269.6953686698196,258.8548830439594,192.91736953285897,334.11033741378253,291.155837726445,269.0209216875405,287.35411488186554,249.4741426468819,262.84330603927583,238.69455917698326,238.61074166694937,243.89159889156707,217.25174817884346,"EOT20","1992-01-01T00:00:00Z",[71,77,80,83],{"name":72,"description":73,"severity":74,"season_start":75,"season_end":76},"Tidal Currents","The mangroves are tidal; snorkelling should be planned around slack tide.
