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.
