Mt Trefle is a 1.7km, grade 2 Circuit hike located in Sydney Harbour National Park New South Wales. The hike should take approximately 40 mins to complete.
This walk explores the bushy interior section of Nielsen Park. On this walk you will visit historic Greycliffe House and the Steele Point Gun Emplacement. The walk climbs over the Mount Trefle summit. At just over 40m above sea level I suspect most walkers will not consider it much of a mountain but an enjoyable walk all the same. Most of this walk follows concrete and sealed paths and there are some great harbour views on the second half of this walk.
