These \"bommies\" (local term for isolated reef outcrops) create excellent snorkeling terrain with boulder rubble, shallow gutters, and small overhangs that attract fish seeking shelter. The beach is backed by a low foredune with low sandstone headlands at either end. Located near Mandorah, this spot offers a wild, remote snorkeling experience in Darwin Harbour, though conditions are heavily influenced by extreme tides. Snorkelers must be vigilant about saltwater crocodile presence — the area is known crocodile habitat — and the strong tidal currents that sweep through the harbour. Access is by boat or via the ferry from Darwin to Mandorah, then a short drive. The bommies are best explored on a big high tide close to the neap phase when the water is calmest and clearest.","advanced",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],0.026444211959682978,0.040266228460664646,0.5790623102781534,0.25259798786908577,1.6594250641602313,0.0749506905848954,0.01793954358828584,0.006883752889820902,0.31567500062178594,0.30225705458599295,0.16115847827181792,0.07361176258285632,0.03723585748071161,0.8911810813141829,0.04860370609938519,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],199.06196216668297,239.49138167492276,202.42025783261465,291.6577283172944,246.96997089897354,91.65836836467815,13.246117100060955,331.3315188408707,227.4774360021117,190.99486225304156,206.29895877648647,177.95534041325715,12.458843199954515,294.7665709974228,295.86337760264786,"EOT20","1992-01-01T00:00:00Z",[110,115,119,122],{"name":111,"description":112,"severity":113,"season_start":36,"season_end":114},"Saltwater crocodile presence","Saltwater crocodiles (Crocodylus porosus) are common in Darwin Harbour and the Cox Peninsula.
