Orchid Bay, Fraser Island - Located on the northern side of Fraser Island, Orchid Beach is considered the more peaceful alternative to the southern resort settlements with no tour buses, day trippers and minimal beach traffic.
Platja des Coll Baix (Spain). 'Isolated coves remote from roads and resorts are something of a secret Mallorcan speciality, but few can rival the Platja des Coll Baix. Accessible only on foot or by sea, this hidden beach on the uninhabited eastern side of Cap des Pinar is a small slice of paradise.' http://www.lonelyplanet.com/spain/mallorca
