This bit of adventure is a must for all visitors to Sydney. The Pylon lookout at the top Sydney Harbour Bridge is a harrowing 200 steps to the top. But those who brave vertigo and the often windy days are treated to the most amazing views of the city, the harbour, and the Sydney Opera House. Plus, you will touch the very monumental structure itself and have a new understanding of roosting pigeons. Inside the pylon, there is also a museum with displays relating to the construction of the bridge, including some great photographs. Admission: Adults AUD8.50; children (8-12) AUD3.
