Carn a Mhaim has to be up there as it is a proper ridge descent.
Whiteless Pike is glorious. Ridden it several times in all seasons. Bloody brilliant and worth doing as a loop to take in Grizedale Pike. With the path being improved a few years ago, it is possible to now ride most of the way up too if you have the legs and low gears.
The ride on the west side of Arran no beer has walked is great on a bike but the hike up is tough. I wrote that one up for the mag.
Ben Avon heading north via the tors is mint. Cracking views too.
Ullock Pike – great but even better adding in Doups.
St Sunday Crag – only ridden it west to east but loved it.
Buchaille Etive Mor – for pure ridge riding, it is a cracker. Feels like skiing heading down into Glen Etive.
Binnean Mor – fantastic trail with everything you could wish for in a descent.
Cat bells ridge line starting at Honister after coming over Rosset on a sunny autumn evening. Just fabulous.
Oh and for sheer loveliness close to home (if you can stand the hike a bike) then the 5 summits in the Pentlands are cracking. Added another 4 summits on yesterday for a brilliant first big ride of the year day out in perfect winter conditions. Finished in the dark as all the best rides should!
Cheers
