Blue Mountains National Park does not have a fee for entry, but there are some costs to take into consideration. If you are bringing a car, some areas, such as the area near Echo Point, may have parking fees. The Glenbrook area does charge by the carload for access. Scenic World charges for admission to its activities. The Jenolan Caves area itself is free to wander around, but you do have to pay for a guided tour to go into the caves. The hop-on-hop-off bus is an extra fee. But most of the area in the Blue Mountains is free of charge to explore.
