Lake Rotoroa, Nelson Lakes
Rotoroa Nature Walk
Time: 25 min return
This walk starts at the picnic area near the lake. At the picnic area an information panel and a small carved wooden canoe reveal the livelihood of an early resident of the area.
The track proceeds along the Lakeside Track for about 10 minutes before branching off to the left onto the loop section. It returns to the picnic area via the start of the Porika Track.
The gentle nature of this ramble is a botanist’s delight. Of all the short walks in the park, this one contains the greatest variety of tall forest trees, shrubs, climbing vines, mosses and particularly ferns. Here the beech–podocarp forest around the lake is at its most diverse.
Time: 2 hr return
This walk leads along a wide and well graded track through a diverse remnant of beech and tall podocarp forest rich in bird life, then zigzags up to a picturesque mossy waterfall.
The track starts 400 m west along Braeburn Road from the Gowan River Bridge. Initially the track follows the remains of a road constructed in the 1950s during the hydro-electric investigations. Flanking the flat section at the beginning of the walk is a grove of distinctive fuchsia trees forming a natural avenue.
Porika 4WD Track
Time: 3 hr return
The Porika 4WD Track heads up onto the northern end of the Muntz Range, which runs along the eastern side of Lake Rotoroa. From here, a spectacular view can be gained of the lake and the surrounding bush-clad, bare-topped mountain ranges.
The track begins at the parking area and campground on the road that branches left after passing the Rotoroa Lodge.
Alternatively, begin at the picnic area and walk a short way (10 min) along the Rotoroa Route, then take the Rotoroa Nature Walk to meet the Porika 4WD Track. This option passes through a delightful area of mixed beech–podocarp forest with an impressive variety of ferns, mosses, shrubs and tall forest trees.
Soon after leaving the parking area, the track zigzags steeply through the beech forest to the lookout points, following the 4WD track that is used to service the power transmission lines. The lookout points are not signposted.
To reach the lookout points and return to the parking area takes approximately one hour. The track, while on the edge of the National Park, is outside its boundary. Be aware that 4WD vehicles and mountain bikes may also be on this track.
By road, St Arnaud, the main entry point for the national park, is 1 hour 30 minutes from Nelson or Blenheim, 5 hours from Christchurch, and 2 hours from Westport. Lake Rotoroa Village is 40 minutes from St Arnaud off SH6.
Bus services to St Arnaud operate on an irregular basis. Phone the Nelson Lakes Visitor Centre for more information.
