O'Reilly's Rainforest Retreat is one of my favourite places in the Scenic Rim and I visit it frequently. The Booyung Boardwalk, featuring excellent interpretive signage, which leads you from O'Reilly's guesthouse to the walkway, which is a series of suspension bridges taking you up 16metres into the rainforest canopy. If you feel adventurous you can also climb ladders to a crow's nest platform 30 metres above the ground and perfect for taking some pics.
The Lower Portals features a beautiful pool along a gorge on Mount Barney Creek. The walk has moderate to steep gradients. If you like, guide from Mt Barney Lodge can add info to your walk, explaining about the environment and habitats that you pass through, and help you to discover the best waterholes.

When the waterfall is flowing after rain, it is best viewed from a lookout platform accessed via a 200m detour from the main circuit.
