From the Lake Janet carpark, follow the track up beside the toilet. You'll start climbing, and soon come out into the open zig-zagging your way up the hill. After a couple of hard km's, you'll find you've reached the Fire House (look out).

Continue up the steep track from the Fire House and on to the service road for a few metres. If you look up to the right you should be able to see a track on the righthand side of the road - follow this. It'll take you along the front side of Mt Grey and you'll wind up the side towards the Cell Phone tower, slowly! Once at the Cell Phone Tower you can look across to the trig in the distance, go down the hill and then climb back up to the trig of Mt Grey.

From the trig, continue straight down the Red Beech track and follow the markers down to the river. Take your time as it is a technical descent, and it's best to refill with water once you cross the river at the bottom. From the river, follow the track out towards the Grey River Carpark. 1km from the Car Park you'll come to an old hut - follow the track right here and keep on going! Also, you'll come to a junction just before the carpark with a Nature Walk is well. Take the lefthand track rather than the right and continue to the carpark.

At the carpark, turn left onto the road and cross over the ford on the river. You'll see the Grey River to Mt Grey track signposts and head up the track towards the summit of Mt Grey again. It's a hard climb with lots of switchbacks, but super satisfying once you get out of the trees near the summit again! Once at the trig, admire the views.

Lastly, take the track you came on back up to the Cell Phone Tower and down the track you came up from the Fire House. From the Fire House continue down the same track back to Lake Janet where your car is parked (enjoy that very well deserved descent)!

  • Access

    Take the Scenic Highway exit in Amberley and follow the signs up to Mt Grey. Park up at Lake Janet Carpark.

    The road is gravel, and a bit rutty, so take care driving. Parking is fine at Lake Janet.

    17 km

    21 minutes



  • Staying Safe


    Follow the markers, but it should be easy enough to find your way!


    Long-sleeved thermal top, Seam-sealed waterproof jacket, Beanie/thermal headwear, Whistle, First aid kit, Survival blanket, Cellphone.

    You can refill at the river halfway down the Red Beech track and again at the river at the Grey River Carpark (before climbing back up Mt Grey again).

    Also, water can be obtained from some creeks on the way up the Grey River track on the way up Mt Grey.

    The tracks can get muddy and slippery in the winter, so take care! Also, the rivers can get dangerous after a lot of rain, so only cross if it is safe to do so.
    Finally, it can get cold up on the tops, so take a warm top just in case.
