A road trip from Sydney to Byron Bay can be a tricky adventure - The Pacific Highway doesn't offer much in the way of amazing scenery. There is, however, an alternative route you can take if you're planning on venturing out on this specific road trip and want to experience as much as you can along the way.
The Blue Mountains in Sydney are the best place to start. Leura, Katoomba, and Blackheath are the main places people visit to explore the Blue Mountains, and are accessible via the Great Western Highway. If you really want to see what the Blue Mountains have to offer, however, it's best to stray away from the main roads. Near Blackheath, you'll find Govett's Leap, which is an often-visited lookout point. Here you'll see amazing views of Bridal Veil Falls and the surrounding green areas.
After the Blue Mountains, drive north to visit the renowned crossing point for the Hawkesbury River, known as Wiseman's Ferry. After the ferry, stop for a rest at Settler's Arms in St. Albans. Continuing on your trip, you'll eventually reach the well-known wine village Hunter Valley. Very close by, there is free camping so you can rest overnight.
The next recommended stop is Tamworth, known as the country music capital of Australia. It's a small town that you can probably explore most of in less than a day, but an interesting stop nonetheless. After Tamworth, you can visit the starting point of the Waterfall Way, known as Armidale. However, it's best not to drive around Armidale really late at night or really early in the morning, as Kangaroos are rampant.
Afterwards, your trip will lead you to Mt. Warning, which will probably be your last attraction stop before reaching Byron Bay. Mt. Warning is Australia's most easterly mountain. The entire climb up the mountain takes about 4 hours, so it's best to start around 2 in the morning if you want to see the spectacular views of the sunrise. After Mt. Warning, you're less than an hour away from Byron Bay.
Along your route, there will be plenty of pubs and restaurants, so make sure you stop for refreshments as often as necessary. Be sure to also keep yourself stocked on petrol, as petrol stations can be pretty scarce on certain parts of this particular trip. It's likely best to plan all of your stops ahead of time. You'll want to make sure you know where all the best rest stops are, and the best camping sites if you plan on stopping for an overnight rest.
As always, the most important part of any road trip is your vehicle. If you're on the hunt for a new car, you can do some comparison shopping at CarSales.com.au and similar sites, just to help you get a feel for what is on the market. If you're a frequent road-tripper, you'll want something spacious and comfortable that doesn't use a lot of fuel. Make sure you check out all the details before purchasing a car. Also, don't forget to bring snacks, water, pillows, blankets, safety equipment, first-aid kits, and anything else you deem necessary for your trips and to cover any emergency scenarios. You can never bring too much stuff if it means your trip will be that much more comfortable!
