If you feel like you're already suffering from the effects of the post-summer blues, why not take a jaunt to Sydney? There's nothing like a long weekend away to refresh your spirits, and Sydney is the perfect balm for any troubled soul.

Here are some adventures to keep your mind off the weather.

Sydney Harbour 

One of the keystones to any trip to Sydney is a visit to the beautiful harbour. Drive along in your Sydney rental car and experience the bays in all their glory.

Going during the weekend means you're in the perfect position to peruse the famous weekend markets, located around the Rocks. Coincidentally, this is also the site where Sydney began so you will be able to take in a spot of history – as well as all that shopping!

You could make a day of it on the Harbour, as there are plenty of activities to keep young and old occupied. Make the most of that lingering sun by driving along to Rose Bay. In this beautiful location you could hire a kayak. Lap up those rays and see how far along the inner harbour you can paddle.

Alternatively, you could wander along the cobblestone cul-de-sacs to see what treasures you can lay your eyes on. Your peepers will be in for a treat at the Museum of Contemporary Art or the Art Gallery of New South Wales. And, don't forget the outdoor sculptures at the Botanic Gardens.

To finish off the perfect day along the waterfront, take your car hire in Sydney along to Watsons Bay where you can watch a glorious sunset over the bay, or enjoy a delicious dinner at one of the many beach front pubs or restaurants along Cockle Bay Wharf.

If you're still hot to trot after all that action, why not head along to partake in the local nightlife scene, at local clubs and pubs in Surry Hills or Kings Cross – make sure you've packed your dancing shoes!

Or, you could see what's playing at the iconic Opera House – this is a must-see location when you're in the Harbour City.

Hunter Valley

If the change of season is hitting you hard, you might deserve some R and R – rest and relaxation. The beautiful Hunter Valley could be just what the doctor ordered.

It is only around a three hour drive away from the heart of Sydney, so you can easily reach this destination without rushing.

You could put your feet up at one of the many day spas on offer for a bit of pampering or try your hand at golfing. This sport is said to aid stress relief and there are three championship golf courses to try out!

For the foodies out there, gourmet attractions pave the paths of the Hunter Valley. Try some of the locally-grown olive oils or take a gourmet cooking class – or wine and food matching – course to see what kind of treats you can learn to whip up in the kitchen.

Plus, there are plenty of award-winning wineries worth sampling in the area as well as delicious cheese makers in Pokolbin. Match a delicious full bodied shiraz with a white mould cheese for a taste sensation.

You could even parcel up some of this cheese to form part of a picnic lunch. There are plenty of spots you could enjoy an al fresco meal while the sun remains to shine.

Horse trekking in the rolling countryside or bushwalking in the Yengo National Park are some great outdoor activities that will help you build up an appetite.

The Hunter Valley is also known as a great spot in which to enjoy a balloon-ride. You will be able to spot those famous wineries from the skies as you look over the beautiful countryside the region has to offer.
