This NOT for the 'faint-hearted', and not recommended on a wet day. Be aware that the geocache at the top: GC1458J - "Big Sister" is rated Terrain 4 - quite realistically. This is an 'Unimproved', but highly recommended Lookout for the experienced hiker.
There is a lookout at the base of Big Nellie, that looks up to the 500+ metre high hill.
"Big Nellie is one of the main attractions of Coorabakh National Park. It’s an imposing rock plug that soars more than 500m above sea level, reminding visitors of an earlier time when the Australian landscape was still being created by volcanoes and earthquakes.
"The best place to see scenic Big Nellie is right near its base, where a handy platform has been built to give clear views over the rocky hump. Take the opportunity of a great backdrop to do some family photography, or if you’re keen on birdwatching, this is a great place to spot some of the local birdlife.
"Right near the lookout are several tables, making this a good choice as a place to picnic as well. Take advantage of the lookout and then settle down to a leisurely lunch, or consider Starrs Creek picnic area for a shadier alternative in the lush rainforest." NSW Tourist website - (

Access: Most 2wd cars would be able to make it to the lookout at the base of Big Nellie, where there is space for four cars. Next the lookout platform is a wooden post, with the 'Hiking' icon, and arrow to point you to the track that leads to the base of Big Nellie. While there are some arrows to direct you, there are gaps, and you may need to backtrack to find the arrows again if you think the terrain is too tough for you.
** There is a sign at the Lookout which reads:
"Big Nellie
"This volcanic peak has an elevation of 542m above sea level.
"Formed access is not provided to the summit and visitors are warned of steep terrain with few foot and hand holds.
