Mount Lyell is a beautiful parkland with a lookout at it's centre overlooking the river on the south and Mosman Park to the north.
The cache is a micro bison tube.
Parking is available close by in a car park off Pethybridge Heights. Its a short but pretty walk to GZ. The view is worth it.
Congratulations to OOH YEH and Redlipsandunicorns on FTF.
