Circular Quay is Sydney's main ferry and cruise terminal, wedged between the Opera House and Harbour Bridge, so most harbour views and boat trips start here. Street performers, harbourside restaurants and small shops keep the promenade busy through the day and into the evening. Because it connects directly to The Rocks, the Botanic Garden and both harbour icons on foot, it works well as a base for exploring rather than a single stop in itself.
Circular Quay serves as the city's main ferry terminal and, due to that, is where all the harbour cruises embark. Since harbour cruises are very popular among locals and tourists, Circular Quay is always crowded, and the atmosphere is electric. Some touristy things to do here are whale watching, taking a boat ride (options include jet boat rides, cruise and aboriginal-led tribal warrior harbour cruises) to explore the beauty of the harbour and its gushing water, exploring the culture of the place, dining and drinking in one of the many restaurants there or simply enjoy the splendour of the city the place has to offer.
