If your intention is to get there ASAP, then a fuel and coffee stop in Buledelah is best. It's half way (ish) and there's a decent coffee shop/cafe and a good old country town burger joint. It gets busy though.
If it's a slow meander you're after, take the trip through the Myal Lakes. Follow the signs to Foster, but check out Smiths Lake (you can walk across it to the mouth where it joins the sea), Blueys Beach and any number of fishing spots alomg the lakes. Beautiful, too. about 7 years ago
