Wedding Cake Rock, located within the Royal National Park near Bundeena, is a popular but potentially dangerous coastal rock formation known for its distinctive white color and shape. The hike to Wedding Cake Rock is moderately challenging, taking approximately 1.5-2 hours round trip from the nearest parking area at the end of Bundeena Drive. The clifftop trail offers stunning coastal views, but visitors should exercise extreme caution near the edges, as the rock is unstable and fenced off in some areas. Solo visits are feasible, but guided tours offer enhanced safety information and insights into the park's ecology and history. There are no significant seasonal restrictions, but the trail may be closed temporarily due to extreme weather conditions. The cost is primarily for park entry fees, around $12 AUD per vehicle per day, and transportation to Bundeena. Plan for a half-day visit to allow ample time for the hike and enjoying the scenery. Accessibility is limited due to the nature of the trail; it's not suitable for wheelchairs or those with mobility issues.
