How to get there:
Check if there is an available train nearby your area. We took it from the city: Adelaide Railway Station, Platform 1 to the Hallett Cove stop. From there you can walk to the north entrance of the Conservation Park. You may get off at the next stop too; Hallett Cove Beach stop, but the walking distance from the station would be longer than the first to the south entrance.
From the Hallett Cove stop, cross to the other side and you will see a pharmacist shop facing the station. Walk down the street into the housing area, turn left, first turning on the right and you should see the access way to the trail walk. It’s about 40-50 minutes travelling time (walk included).
There is definitely more to this walk (10km!), but we preferred to walk along the coastal area because it was so sunny and watching the sea somehow cooled and comforted us. Would definitely return to finish the walk!
P.S: If you’re hungry, you could stop to eat at the Boatshed Cafe near the south entrance. The food is pretty good.
