Hard track
This enjoyable walk follows an old management trail from Rennix Gap to the panoramic views from a granite outcrop, which is also home to a Snowy Hydro radio repeater. On this walk, you will visit a variety of environments from open grassy plains, wooded forest, exposed granite outcrops and alpine fens. Let us begin by acknowledging the Ngarigo people, Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.

Track Notes
Turn by turn instructions & maps
Getting started
From the car park and picnic table, this walk heads around the timber posts and follows the arrow past the 'Rennix Walk' information sign, downhill along the old management trail. After about 100m, this walk crosses a creek, then a short time later turns right at a 'Y' intersection (following an arrow) up the gentle hill. Here the walk continues along the side of the hill, through a grove of trees then winds up the side of the grassy valley. After a while, the track bends left to cross the grassy flat and leads across a flat timber bridge. The old management trail then leads up the hill and through another grove of snow gums, and about 400m after the timber bridge, this walk comes to a large flat saddle with a small wetland and views towards the main range (on your left).....

Rennix Gap (about 6 m back from the start).
Rennix Gap
Rennix Gap

Rennix Gap is a signposted saddle on the Kosciuszko Road and is home to a car park, picnic table and the Rennix Walk trackhead. The gap is named after W.E. Rennix, who was appointed the Shire Engineer (with a salary of £350 per year) and was the first to survey the road to Kosciuszko. The road was constructed between 1906-09. A sign at the trackhead reports that Rennix died from pneumonia after having been caught in a blizzard at the gap.

After another 115 m cross the ford.
After another 55 m cross the ford.
After another 1.8 km find the "Lakes Creek saddle" (70 m on your left).

Lakes Creek saddle

This saddle (as with a few other saddles on the Rennix Walk) is home to a significant wetland. This 'Alpine fen' is fed mostly by ground water from the surrounding hills and is an important ecosystem. Please admire the wetlands from a distance, and remain on the main track.

Giants Castle

Giants Castle is the informal name for the larger of the granite boulder outcrops and home to a couple of old trig stations. This is a pleasant spot to rest, about 1km south of the radio reflector.

Continue another 870 m to find the end. Then turn around here and retrace the main route for 6.4 km to get back to the start.
About 25 m past the end is "Radio repeater".
Radio repeater
Radio repeater

This high point, topped with a large granite boulder, provides a great view of the surrounding area. The rock is home to a large radio reflector. This passive device acts like a mirror to bounce radio signals between two Snowy Hydro sites. The reflector looks like a billboard advertising green paint, but the simplicity of the design helps increase the reliability and reduce maintenance. There is also a small active, solar-powered repeater on site. The rock behind the repeater slopes down to the ground, providing access to the base of the repeater and the great views. Take care on the rock, as there are no fences but a significant drop.
