Right.
Campsies. Follow waterboard trail to just outside Killearn then can head up a Land Rover track which takes you all the way up to Earls Seat. You can also cut off it and it will bring you out part way up Dumgoyne.
It’s possible to follow quad bike paths to Fintry with only ten minutes of indistinct trail at the end before a steep but over too quick into Fintry. Alternatively, cut east at the stone cairn above Dumgoyne and you can head across onto Slack Dhu. Mostly quad bike tracks then singletrack. You can descend down to Cantywheerys on a belter of a grass track or follow the cliffs along and drop into Blanefield though I’ve still to get a trail that doesn’t involve a hike at the base the hills to get through the houses in Blanefield.
Mugdock has loads. Just follow your nose or come out with GMBC.
There is also the beast of a climb behind Wheelcraft up then back down the Knockie Buckle. Again, a very fast descent and really stiff but 100% doable climb if you have the legs for it.
Another good wee loop is to follow the Allander and Kelvin into Maryhill and return via the woods parallel with switchback road.
Others include the Whangie, the Kilpatrick Hills and Windy Hill.
