You can try south of Rippley road from centenary highway (springlfield) and that ends in Beaudesert, then from there you can go to mt barney. I did it last weekend and is an easy but nice and beautiful drive, plenty of small river crossings. DOgs will love it as well. and most important is not national park so you can take them.
Hope this one helps.
