Ada to Starlings Gap via New Ada Mill is a 16.1km, grade 3 One Way hike located in Yarra State Forest Victoria. The hike should take approximately 5hrs to complete.


This is a very beautiful Ada to Starlings Gap via New Ada Mill hike that passes the Ada Tree. One of the largest trees in Australia, at 76 metres high. It passes through some very beautiful and lush rain forest. It has well deserved reputation as a very scenic walk.

Starting at the Ada Tree Picnic area, after approx 1.6km you will come to the Ada Tree. Then follow the marked trail to Federal Mill and on to the Crossroads. Where you can take the diversion to the New Ada Mill (or Ada Mill if you wish). After returning to the crossroads continue to Starlings Gap.

The trails are mostly over old tram tracks and therefore of gentle incline. The Ada to Federal Mill is over gently undulating ground, plus from Crossroads to New Ada Mill is a mild incline.

Overall one of the most beautiful hikes in the Melbourne Area for sure.

Getting there

There are various routes to do, but perhaps the simplest is to find your way to Powelltown (assuming you come from the West), then look for the turn off to Big Creek Road on your left (roughly 6km after Powelltown). Follow the signs to Ada Tree.


  • This area can have a lot of leeches so bring your favourite leech remedy or repellant.
  • This can be started from either end, just make sure you have transport arranged at the end.

    1. Might have to bring the swag or find a 5 star hotel ladies ?1hr 37 mins from Merricks North, so 2 hrs from you, plus 5 hrs walk…maybe…and 2 hrs home. Doable✅ but more funable with a sleepover in between ?

  1. Question: As the end point of this walk ends at about 16000m Altitude, would that be a good practivce walk to prevent altitude sickness which many people suffer when trekking in South America
