If you’re in the outer West of Melbourne, these are the few I can recommend which won’t involve crazy drive times to get to…
You Yangs is always good, but if you don’t like snakes, there are certain months you may wish to avoid it.
Some great views.
Werribee Gorge (the main circuit) is a really enjoyable and sometimes challenging (would recommend trekking poles) 2-3hr hike.
Interesting section whereby to traverse you need the aid of the cables attached to the rockface.
As evidenced here by my crapola phone footage…
Brisbane Ranges National Park is one I’ve done also.
The Ted Errey Nature Circuit was a good walk.
A few hours at least.
Once this COVID sh*tshow subsides, I’d like to do some more challenging 5hr+ hikes.
