The geology around Yampi Sound is spectacular: the rocks were spectacularly folded and buckled by pressure during the collision between two landmasses approximately 550 million years ago. During your call at the Yampi Peninsula, you will have the opportunity to undertake a zodiac expedition to view the amazing geological features. The horizontal sandstone strata have been bent 45-90 degrees in some areas, and erosion created incredible sculptures and fantastic shapes. At the right time of the year it is possible to see Australian humpbacked dolphins and the elusive snubfin dolphin in the Bay.
