Ideally you want to know where you are going or at least be able to pinpoint your location when you start to feel lost. You can find a map by searching National Park trail maps Australia to get local information on maps for that area, and perhaps even the software to help you keep a digital version of the maps wherever you are. The apps can be loaded directly to your phone and access whenever you need it. If you have a phone with a GPS receiver built in then you can get real time location services to tell you exactly where you are and how you can get to your destination as quickly as possible. If you prefer to be a little more adventurous then you can plot out routes that are a bit steeper or require some climbing. You can put your outdoor skills to the test by camping out on the hillside, setting up tents and starting a campfire to cook food or to keep warm. If you bring your dog along for company then you can find fun things for them to do along the way. They always enjoy being outdoors so if you can take a route where there is plenty of space for them to run then they will enjoy the trip thoroughly. Your children or your partner can help you plot out where you plan to go for the day to ensure that everyone has a great time.
You may want to keep their physical abilities in mind before deciding the route and an app with the latest area information can help you achieve that.
