Rat-a-tat is a bush campsite in the Green Mountains (O`Reilly`s) section of Lamington NP. There is water at the campsite and an earth bank which hosts a wonderful display of glow-worm lights. We start walking on the Border Track before joining the Albert River Circuit at the second junction.This is an easier and quicker way to get to the campsite. We pass Echo Point on the way with great views to Mt Warning and NSW. On our return we will take the left arm of the river with it`s wonderful falls, Lightening, Echo and Mirror to name a few to complete the Albert River Circuit.
