Paluma Dam, Big Crystal Creek (Paradise waterhole)
Closer to Ingham - Wallaman Falls, Broadwater State forest, Jourama Falls, also Lucinda caravan park
Rollingstone Caravan Resort is nice - a Big 4 so not cheap. For more space, you can camp up past the pool and be almost right on the beach, (avoids the 'glampers' with their flatscreens, evening karaoke, air conditioners running half the day)
