Palm beach is bounded by Broken Bay to the north the Tasman Sea (within the South Pacific Ocean) to the east Whale Beach Avalon and Clareville to the south and Pittwater to the west. Barrenjoey Headland which is in the north of the suburb is part of Kuring gai Chase NationalPark. The headland at the northernmost point rises quite sharply from the beach to over 100 metres (330 ft) above sea level and features an operational lighthouse. The narrow sandy isthmus or tombolo linking the south side of the headland to the rest of Palm Beach had extensive fencing and shrub planting undertaken during the 1980s to combat sand erosion.
