Barrenjoey Lighthouse, a iconic landmark at Palm Beach, offers stunning panoramic views of the coast. Access requires a moderate walk of 30-60 minutes up either the steeper Smugglers Track or the gentler Access Road; it is not wheelchair accessible. While the exterior and surrounding views can be enjoyed solo at no cost, guided tours of the lighthouse interior are often available on Sundays and select weekdays for a small fee (e.g., $5-10 AUD), so check the NPWS website for opening times. The area is open year-round for walks, though it can be hot in summer; whale watching season (May-November) is particularly popular. Allow 1.5 to 2.5 hours for the round trip and time at the top. Paid parking is common at the base of the walk, so factor in around $10-15 AUD. Remember to bring water, wear comfortable shoes, and use sun protection for this rewarding experience.
