Explore the venerated Hunter Valley region during a private guided tour. Soak up the countryside's vivid natural scenery, taste fine wines at a fabled vineyard, and sample outstanding, preservative-free cheeses before returning to Sydney as evening settles on the city.

Get picked up from your Sydney hotel and allow your knowledgeable guide to whisk you north across the Sydney Harbour Bridge. During the picturesque drive, allow your guide to answer your questions about this hilly region fed by the rushing Hunter River. Your first stop lands you at the endlessly fascinating Australian Reptile Park. Inside, see snakes, lizards, and crocodiles, and learn about endemic Australian species like Tasmanian devils and kangaroos.

From the reptile zoo, feast your eyes on a fudge-production facility—the Hunter Valley Chocolate Company. Learn about this flourishing business before quenching your thirst at a 40-year-old wine estate. Marvel at the untouched countryside while sipping award-winning varietals like chardonnay and cabernet sauvignon. Treat yourself to lunch at the vineyard's cafe while saving room for your next stop—a local cheese factory.

At an innovative establishment that produces exceptional preservative-free cheese, sample a savory cheddar made using a traditional recipe. Before returning to Sydney, delight in a bit of exercise. Peruse an international garden with 5 miles (8 km) of pristine walking paths for your enjoyment.
