The iconic Sydney Opera House is a must-visit, offering various experiences. It is largely accessible with ramps, elevators, and accessible seating, though specific performance areas may have limited access, so it's advisable to check in advance. While you can admire its exterior solo for free, guided tours (ranging from 1-hour standard tours to 2.5-hour backstage tours) are highly recommended for in-depth insights, costing approximately AUD$30-AUD$90+. Attending a performance, with tickets varying widely from AUD$50 to hundreds, offers the full cultural experience. There are no seasonal restrictions as it's open year-round, but performance schedules change, and peak tourist seasons (summer, holidays) mean more crowds, so booking tours and tickets in advance is crucial. A typical visit duration can be 30-60 minutes for an exterior walk-around, 1-2.5 hours for a tour, and 2-3 hours for a performance. Photography rules inside venues are strict, and dining options are available on-site.
