Darwin, Australia. Most people have barely heard of the city. FYI it is on the coast of one of the most northern parts of Australia. The city is famously named after Charles Darwin, but that's not what makes it worth visiting. It's worth making the trip to this northern city to check out the three major national parks near it. Visiting Kakadu, Litchfield, and Nitmiluk National Parks can be done in a day or can make for a fun-packed camping weekend with friends and family.
The main attractions at these parks are the gorgeous waterfalls that are embedded deep in the rainforests that the parks reside in. For a good workout, be sure to hike up the trails that lead to the rock formations and waterfalls. Expect the temperature to be sweltering hot and humid. If possible, visit Darwin during the dry season, Australian Winter (June-mid August), before the temperatures sky rocket in September.
Go shopping and grab a drink at a pub by the Darwin Convention Center. Restaurants here offer beautiful views of the Darwin Harbour. If you are looking for another activity, take a day cruise from Stokes Hill Wharf to see sea turtles on Bare Sand Island. Or, visit the Charles Point Lighthouse.
If you find yourself in Darwin on Thursday or Sunday, be sure to make your way to the Mindil Beach Sunset Markets at night. To be fair, the souvenirs sold at the markets aren't very high quality, but they are still fun to look at. Go for the street food and entertainment and sit on the beach for sunset.
