Not a lot of info on the NSW NP's website...which i find very annoying to navigate.
General safety info...
http://www.nationalparks.nsw.gov.au/safety, click on the 'read more' link, again annoying, just a drop down info button.
There is a info board with all the walks marked on it as you drive into the Bald Rock NP camp area.
Water sources :- Bald Rock creek, Carrolls ck & Bookookoorara ck on the Nsw side.
You can also use Nsw's Bald Rock NP as a gateway to explore Eastern Girraween via it's easy walking firetrails
with scrambly side trips to various bouldery outcrops with great views if you like that sort of thing.
Long & short circuits available + bush camping.
Water sources....Racecourse ck & Paling Yard ck + tributaries on the Qld side.
A few more walks are available at Boonoo Boonoo NP, plus a waterfall & a great view from Timbarra Trig in the Basket Swamp NP,
both just down the road. Again not much info out there on the Basket Swamp NP.
