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 southernmost track and also the steepest is the Rimu Track, also known as Rimu-Totara Track, which is directly accessible from the road through the park, by the junction with a short road past a substation to Lake Mangapapa. The side road has a closed gate, with public access for walkers only.
The Rimu Track is short, but quite steep in places, and with numerous steps. It climbs from the road junction through a valley to a plateau with an easy loop track, and a side track down past 3 large rimu trees (The 3 Sisters) to the road leading to Lake Mangapapa. The road can then be followed back to the junction, or a side road and track can be taken back up to the Rimu Track.
