A woman hiker has been missing for four days in dense bushland in a far north Queensland national park with a ground search under way after an air search failed to find her.
Juliana Castrillon, 38, was last seen hiking away from Cedar Bay towards Home Rule in the Ngalba Bulal National Park, south of Cooktown, on Saturday morning.
The ground search was launched after a two-day aerial search failed to find any trace of her.
“These efforts were hampered by poor visibility due to the dense terrain,” police said in a statement on Wednesday.
“A ground search and rescue will recommence this morning utilising police on foot, along with SES volunteers.”
Ms Castrillon is 169cm tall with black hair and brown eyes. Police have urged anyone with information about her whereabouts to contact them.
