If you're looking for the perfect picnic spot close to the Sydney city then I'd highly recommend Observatory Hill. Featuring a million dollar view of the harbour, the Sydney Bridge and North Sydney this is a popular spot for locals, and visitors.
You can use the park for free, and it's very well maintained.
The closest public toilets are located on Watson Road, at the foot of the Lower Fort Street park entrance.
Featuring exercise stations, public artworks, a rotunda available for hire and a tennis court - you won't get bored here.
How to get there? Take the Agar Steps from Kent Street or from Cumberland Street get there through a cutting in the Harbour Bridge and a pedestrian bridge from the city centre via the Bradfield Highway.
If your using public transport the 431 and 432 to Millers Point are the most frequent. The red Sydney Explorer bus routes 300 to 500 also travel nearby.
If you don't mind the walk you can catch the ferry to Circular Quay or train to Wynyard station and walk to the park.
The Sydney Observatory is location on the the hill, it was built in 1858 and it's definitely worth taking a peak - lucky for us it's open throughout the year.
If you have plans to take the dog with you on your picnic, Observatory Hill Park is an off-leash area at all times.
What better way to spend some quality time with your partner then overlooking the Sydney Harbour?!
Not only is this a very affordable date, it is super romantic and allows you and your partner to talk and create memories!
