Turros Heads NSW (near Batemans Bay)

state forest is 20min south.loads of good riding there

Theres nothing at TH (my folks live there, I've looked....hard). But look into Mt Dromedary at Tilba. Solid ride up, then a fun ride down (assuming that you enjoy gravity).

Contact Moruya Cycles. They might be able to help (but they may not be willing to talk over the phone. Moruya is only 20 mins north of TH).

Bermagui Dirt Surfers might be open and there is Mogo as mentioned.

Plenty of fire trails in Deua NP and some ST if you look but just make sure you have a GPS or map (ask me how I know).

I can recommend the Tern Inn for food in TH (the rest of TH is pretty limited for decent food). Or the Pickled Octopus down near the Boatshed (Tuross Lake) is quite nice (haven't been for a few years mind you).

Other top tip, don't swim in the ocean!!

I was near there a couple of weeks ago. You are basically 30-40 minutes drive from either:

Both tracks are in great condition, Mogo is a longer loop and probably has the edge for fun-factor.
