The snorkel terrain runs roughly 50m offshore over a sandy, weedy bottom dotted with small coral patches. Sheltered inside King Bay on the Burrup Peninsula, the site offers calm conditions perfect for beginners exploring tropical marine life. Trailer and car parking is available right by the beach, and the boat ramp also provides easy water access. Snorkeling is best at low tide when the coral gardens are just beneath the surface, revealing tropical fish, rays, and occasional turtles in warm Pilbara waters.","beginner","https:\u002F\u002Fhowsthespot.syd1.cdn.digitaloceanspaces.com\u002Fspots\u002Fimport_back-beach-karratha_0_e98f58ba3b55.jpg","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],0.022239772830258436,0.009134948790082188,0.23786874032859096,0.2214919072894389,1.2992423722450201,0.028448668298918497,0.011320842209648947,0.004209635858160399,0.23158984490980278,0.14526296972698038,0.06684174868509768,0.03304176818683429,0.017379717447592914,0.794259818549115,0.03935491147192414,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],20.086543008747526,191.0064713531507,173.23713424138307,133.36009453955813,75.42024052172653,16.507946745957952,358.6160126094584,232.84467989377958,47.21849667246789,162.0560767436151,166.31167641931884,157.50321261868362,3.5377137988863296,136.55512497817875,144.62575774028392,"EOT20","1992-01-01T00:00:00Z",[71,77],{"name":72,"description":73,"severity":74,"season_start":75,"season_end":76},"Boat traffic","The boat ramp and adjacent waters see boating, fishing and swimming activity, especially on weekends.
