Backed by towering dunes and coastal vegetation, the beach opens onto the wild Southern Ocean. Protected by the bay's gentle curve, the water beyond the shorebreak offers clear conditions for snorkelers to explore. The area is also home to Remarkable Cave, a dramatic sea-carved tunnel visible from the lookout above. A walk through coastal heath and dunes leads to the sand, making this a full nature experience.","intermediate",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],0.012940738751134752,0.009541531908443358,0.19588587403883617,0.010573168339781142,0.24539837846067597,0.0022869433303118534,0.008404922647629409,0.0031333381059631678,0.06925820705176734,0.1309879439916352,0.05916056424546011,0.031427717130937546,0.009391895909757962,0.012519903496987493,0.004385518887220747,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],267.81392790654536,317.5087761008241,296.8470543188495,259.35390504842866,310.61381430129336,241.01129763205756,155.03355716343447,185.8776550375906,296.9444291327982,271.2754059878172,291.6107474100536,252.81540123885577,30.30116006109463,284.1336495862413,200.88410645610975,"EOT20","1992-01-01T00:00:00Z",[71,77,80,86,89,92,96,99],{"name":72,"description":73,"severity":74,"season_start":75,"season_end":76,"category":17},"Strong shore break and swell","Crescent Bay faces the Southern Ocean and can experience powerful waves and a strong shore break, particularly during southerly swells.","warning",6,8,{"name":78,"description":79,"severity":74,"season_start":17,"season_end":17,"category":17},"Rip currents","As with many exposed Tasmanian beaches, rip currents can develop, especially when swell is running.",{"name":81,"description":82,"severity":83,"season_start":84,"season_end":85,"category":17},"Cold water temperature","Southern Ocean waters are cold year-round, rarely exceeding 16°C even in summer, posing a cold shock\u002F Hypothermia risk without appropriate wetsuit.","caution",5,12,{"name":87,"description":88,"severity":83,"season_start":17,"season_end":17,"category":17},"Remote location with limited facilities","Limited phone reception and no lifeguard patrol; emergency services access can be delayed.",{"name":90,"description":91,"severity":74,"season_start":17,"season_end":17,"category":17},"Steep cliff edges","Unfenced steep cliffs along the Mount Brown coastline and summit track present fall risks.",{"name":93,"description":94,"severity":95,"season_start":17,"season_end":17,"category":17},"Maingon Blowhole","Unstable, fragile edges surround the Maingon Blowhole cavity near the start of the walk.","danger",{"name":97,"description":98,"severity":83,"season_start":17,"season_end":17,"category":17},"Loose scree on ascent","The Mount Brown summit trail passes over sections of small, loose shards of rock that can be slippery.",{"name":100,"description":101,"severity":83,"season_start":17,"season_end":17,"category":17},"Remote beach access","Crescent Bay is only reachable by foot or boat with no lifeguard patrol or immediate emergency services.",{"directions":103,"parking":104,"facilities":105,"fees":107,"access_method":108},"From Hobart, take the Arthur Highway (A9) south to Port Arthur.
