10. The Pinnacles, Australia

The Pinnacles in Australia are splendid limestone formations located in the Nambung National Park in the Western part of the country. The raw material taking part in their formation had been produced from seashells in earlier periods of time affluent in marine life. These shells were transformed with the time into lime rich sand, blown inland and formed very high dunes, whose lower levels have been cemented by the rain into a soft limestone. The area has gained its world fame after it has been added to Nambung National Park. The best months to enjoy the great view of the Pinnacles formations are from August to October and especially in the early morning and late afternoon when the playing sunlight makes their colours contrasting with their shadows in an amazing way.
