The name doesn't necessarily say it all — this beach is far from treacherous, but, it is isolated. Situated near the popular Seal Rocks beach area, about 40 minutes north of Newcastle.The beach is a little "off the beaten track".

A drive through the heavy bushland will get you to the best spot to access the beach, Treachery Camp grounds. 'Free form' camping rules here (that is, no set camp sites), though for those not into "roughing" it too much, there are also basic holiday cabins available. A general store one kilometre away supplies the necessities.

A short walk over a sandy hill at the fringe of the camp area will see you standing above the white sands of Treachery Beach, and from this viewpoint, it feels as though the beach goes on forever, with nothing (nary a beach umbrella to be found) in sight but sand, waves and blue sky.

There is excellent beach and rock fishing, with the months of March, April, May and June being the best. On some days, pods of dolphins can be seen frolicking off the coast. Pitch your tent, hang up the hammock and slap on the sunscreen for some uninterrupted and unspoilt swimming and surfing.
