What an amazing concept! The Parklands is a continuous ring of green space surrounding central Adelaide and is comprised of several individually numbered parks with different characteristics (some more stylized, some more pastoral, some more for children/entertainment/sports).

We split up our walk through the Parklands over several days, which I’d recommend. There’s a walking trail loop easily identified by the blue circle markers on the ground (though it can disappear at times and then pop up unexpectedly—good to also follow along on a map or on your GPS). It’s a total of a little over 12 miles (19.5 km) to do the entire loop, but it can be split up in three sections which are easily accessible using the free sections of the Adelaide tram (the northern half above the River Torrens, and then the right lower fourth and then the left lower fourth). Also, it can be combined with sightseeing at many of the spots along the way, which is what we opted to do. Overall, def recommend doing if you’re in Adelaide! Never seen anything like it in any other city I’ve visited.
