With city sights, a coast of cliffs, lush forest, waterfalls and wildlife, a tour from Melbourne to Adelaide is must do in Australia. With so much to do and see, it can be difficult to narrow your options, so here are a few suggestions.

Gain perspective on your trip to come by viewing it from above. Spend a leisurely morning floating in a hot air balloon; after enjoying views of Melbourne, Australia's second largest city, from above, indulge in a delicious hot breakfast while sipping champagne.

Next, see the city from its streets. Visit Federation Square, Fitzroy Gardens, Southbank, Docklands, the Royal Botanic Gardens, and the Eureka Skydeck. To ensure you see Melbourne's highlights in an efficient way, trust an informative guide to bring you on a city tour.

You're now ready to take to the roads. The drive to Adelaide is not to be dreaded; it is spectacularly scenic. Self-drive as a flexible and affordable way to see the breathtaking sights of the cliff-hugging Great Ocean Road.

Outside of the city, you will be driving along vineyards, rocky shores, and beaches. Take a break to ride the waves at the iconic surf spots, Jan Juc and Bells Beach. If you prefer, have a game of golf on a scenic course in Anglesea, where grazing kangaroos frequent the fairways.

From here, you may want to spend the evening in resort town Lorne, which combines boutique shopping, restaurants and cafes with natural highlights, such as the Angahook-Lorne State Park.

Otherwise, drive through where the cliffs of the rugged coast meet the lush ancient rainforests and arrive at the fishing and farming village, Apollo Bay. While exploring the Otway National Park, trek through the rainforest to Erskine Falls and marvel at the Otway Ranges.

Drive through thick forest canopies with waterfalls and shorelines by your sides until you see the London Bridge and the Twelve Apostles standing high out of the water. You've arrived at the Shipwreck Coast, home to over 200 wrecks. Enjoy the views of the limestone towers carved by the wild seas over thousands of years from the boardwalk or from Gibson's steps, an area of cliffs leading down to the beach. If you're there between May and September, visit Logans Beach to spot whales.

If it is time for a rest, spend the evening in the quaint and history-filled costal town, Port Fairy, home to many heritage buildings. You may see the nation's largest fur seal colony there.

The next must-see on your trip is Mount Gambier,a maar complex containing several crater lakes such as Blue Lake, named after the brilliant colour it turns between November and February.

You should also try to visit Grampians National Park, which offers spectacular lookouts, inspiring waterfalls such as Mackenzie Falls, and unique wildlife. You may chose to spend the night in the seaside town of Robe, once known as one of South Australia's most important ports.

Next, travel to Naracoorte to see its World Heritage site, an area composed of 26 limestone caves that house giant prehistoric fossils.

Almost to your final destination, make one last stop to enjoy the Fleurieu Peninsula. There, see penguins on Granite Island or do a cliff-top walk to Port Elliot. Now to Adelaide!

If that seems like too long a drive, let someone else do it for you. Take a guided 3 day Melbourne to Adelaide safari, which brings you to many of the highlights and includes two nights' accommodation and meals.

Once in Adelaide, take a guided city tour to visit Victoria Square, the Terraces, and Colonel Light's Lookout on Montefiore Hill, among many other highlights. Finally, top your trip off with a day in pristine wilderness on Kangaroo Island. See sea-lions bask, koalas nap, pelicans soar, penguins waddle, and kangaroos leap on this diverse island. This natural wonderland is truly a grand finale to a great trip!
