Distance from Sydney: 37km
What list of Sydney’s nearby national parks would be complete without the majestic OG? Less than an hour from the hustle and bustle of Sydney’s CBD, you’ll find a whopping 15,091 hectares of bushland hugging the coast south of the city. Whatever outdoor pursuit you’re in the mood for – swimming, surfing, hiking, biking, bird watching, camping, or just chilling out in nature – you can find your fix here. Serious walkers should set their sights on the 26km coastal trail, which usually takes two days to complete. Plus, there are platypuses there now, so we hear.
