With winter well and truly behind us, it's time to dust off that gym gear and think about getting fit again. While it's nice to hibernate in front of the telly all winter, it helps to be active during the warmer months. Time to swap that Game of Thrones box set for playing outdoors!

If you're heading on holiday soon, never fear, taking a leisure trip is actually an excellent way to tone up and stretch those legs. Let us use sunny Adelaide to illustrate this example. Surrounded by beautiful scenery, this South Australia hub has plenty of natural landscapes for you to explore.

Here are five great outdoor activities to do in this lovely part of the country. Simply pick up your car hire in Adelaide, throw some gear in the back and enjoy a holiday of exploring.

Cycle the River & Coast Ride

One of the best ways to see Adelaide and get a tan at the same time is to hop on a bike and cycle the River & Coast Ride. This 30km loop leaves from the CBD and takes you along a bike path following the River Torrens until you reach West Beach.

Be sure to take a backpack with your swimsuit so you can cool off in the water at the halfway point. It's also a good idea to pack plenty of sunscreen.

Explore the Adelaide Hills

An advantage of having a car rental is you can explore a bit further out from the city. Jump in the car and head to the Adelaide Hills for a day of hiking. No matter what your experience level, there will be a track in the hills to suit your needs. Whether you're keen for a relaxing stroll or you want to climb like you mean it, you'll have your pick of many different tracks.

A particular favourite is the Hills Short Wine and Food Trail. What better way to endure exercise than by tasting wine and nibbles along the way? A brainchild of local food and wine producers, the trail includes several orchards and vineyards.

Make a splash

Summers in Adelaide are not known to be mild. If the last thing you feel like doing in the heat is going for a walk or cycle, cool off in the water instead. There is an abundance of water activities to try in this South Australian city.

Why not rent a kayak and paddle to the port? Or perhaps you could jump on a jet ski and see the city from the sea? Adelaide is also home to some great beaches, including Normanville Beach which is just an hour's drive south of the CBD.

Go camping

Sometimes being outside is enough. Forget the sweating and exercising – if reading a book in a beautiful campsite sounds like your idea of a perfect holiday, we can hardly blame you. There are some wonderful campsites in Adelaide and surrounding areas, so pitch a tent then sit back and relax.

Camping is often the best way to get up close and personal with nature. Go to sleep when its dark and wake at sunrise. Take your pick of beachside camping grounds or those located further back from the coast in the bush. And if the weather turns sour at least you can hop in your car hire and find a drier place to stay in the city. By hiring your car from East Coast Car Rentals, you'll always have the flexibility and freedom to adjust to whatever weather your holiday might throw at you!
