You don't need tickets to enter, so I'm not sure why that option is available. However, if you're driving around Rainbow Beach, you should definitely check out all the viewpoints. When we visited, it was just us and another family there. It's very easy to access, but since we wanted to spend more time on Rainbow Beach, we didn't stay long. The views are stunning, and if you're looking for a quiet spot to enjoy the sand and sea, I highly recommend it!
We visited this location for a camping trip, and it turned out to be one of the best we've ever experienced. We're so glad we chose this spot, with camping at just $7 a night and a beach vehicle permit for $35 for the week. It's an unbeatable deal. Rainbow Beach is about a 45-minute to 1-hour drive away, depending on traffic. This is a fantastic destination for families looking for a long weekend getaway or a school holiday trip. A 4WD vehicle is necessary to access the camping sites. Highly recommended.
