If you’re looking for a moderately long hike with gorgeous views that’s also very dogs-off-lead friendly, give the Pioneer Women’s Trail from Beaumont up to Mt. Osmond a go. It’s a winding 7.2 km out-and-back walk with about 180 metres of elevation change. At a brisk pace it takes about 80 minutes for me, but it’s worth slowing down for the views of the city, suburbs, coast, and airport.
Start at Brock Reserve (///moving.dangerously.deeply, OpenStreetMap) on Dashwood Road, then follow the signs until you get to the top. If you’re walking next to the golf course, you’ve gone too far. There are plenty of shortcuts if you want to go for a steeper, but shorter variant of the walk – you’ll probably see plenty of people coming up Bayview Track, Centre Track, and Travers Track when you’re out there.
