We only did the easy part from the park HQ to the Berry Creek waterfall and then we turned back. It took us around 4 hours to get there: we stopped a lot to take pictures, climb rocks on the stream and giant fallen trees on the side of the trail. It only took us ~1 1/2 hours to get back.
There are more (smaller) waterfalls going up. But it was getting dark and we were too tired already. You should might want to try if you have energy ;)
It’s a beautiful hike for sure :)
