Despite the nay sayers, there is a lot of good stuff up there if you know where to look! 😆
Knockie Buckle – out and back from Wheelcraft or as a circular route that drops down into Lennoxtown. Very steep but multiple line choices for the fast descent back to Wheelcraft. As an out and back, it's terrific. Short and hard but plenty of descent for the return leg.
Dumgoyne – some nice stuff round the base of the hill. Gnadgery narrow singletrack. Dumgoyne itself as a carry up and ride down is pucka. Just don't fall off the cliff edge!
There is also a trail that takes you from just before Killearn all the way up to Earls Seat. It's a climbers dream. 100% rideable if you have the commitment and the legs for it. You can also ride across to Fintry on old quad bike tracks. Fairly easy to follow when there is no cloud cover with some cracking views over the Highlands.
Another favourite is to climb up the trail from Killearn then head across the quad bike tracks / sheep tracks onto Slack Dhu. There is a great descent off Slack Dhu heading towards Dumgoyne that connects up to the Cantywheerys track as Doug mentioned. I basically went up there and followed my nose. There is some nice sheep track that goes along the top of Slack Dhu.
Come along to GMBC in Milngavie (www.gmbc.org.uk) on a Wednesday night with a map and I'll happily mark it up for you. I'll be the loon on the white Turner.
Cheers
