McLaren Falls Park is accessible from McLaren Falls Road, which branches off State Highway 29 about 19 km south-west of Tauranga. There are numerous walking tracks within the boundaries of the park, with most of them providing easy walks on well-formed and wide tracks. The Lakeside Walkway runs almost the full length of the eastern side of Lake McLaren, from the road entry off McLaren Falls Road almost to the access road to the Lower Mangapapa power station. The Waterfall Track branches off the Lakeside Walkway, crosses over the road and then loops alongside a stream on the way to and from the small waterfall.
Ruahihi Canal was constructed in the late 1970s and early 1980s to lead water from Lake McLaren and the Wairoa River to the Ruahihi Power Station adjacent to SH29. The canal is about 2.5 km long, with water then being fed into penstocks for the final part of the journey to the power station. The penstocks are mainly underground, but the single penstock pipe can be followed from the end of the canal as far as Gunga Lane and Ruahihi Road. At some point the single pipe is split into the two which can be seen alongside SH29, across the road from the power station.
On most days the Wairoa River from McLaren Falls to the power station is only a trickle, but on some weekends the control gates are opened and the river returns to a normal level during the day. The river is popular for white water rafting.
