Accessibility varies across the region, with some areas offering wheelchair-friendly paths while others are more rugged. Solo exploration is possible, particularly with well-marked trails, but guided tours provide deeper insights into the area's history, flora, and fauna. Seasonal restrictions may apply to certain trails due to weather conditions or bushfire risks, especially during the Australian summer. The cost of a visit can range from free for self-guided hikes to several hundred dollars for organized tours, accommodation, and activities like canyoning or scenic railway rides. A typical visit duration can range from a day trip to several days, depending on the desired level of exploration.
