The 22 m falls are on the Tautuku River in Catlins Conservation Park and are often described as the most spectacular in the region. The walk to the falls, though uphill, is not too steep and very pleasant.
It passes through a variety of forest and shrub types: huge tree fuchsia, stands of olearia and podocarp forest.
The McLean Falls are well signposted off SH92. Heading south, beyond the Cathedral Caves turnoff, turn right onto Rewcastle Road. The McLean Falls carpark and toilets are 10 minutes from SH92.
