You could start at Glenmore, ride and hike onto Mealle a Buchaille, tech descent to Ryvoan, out past Forest Lodge to Loch Garten, ride the trails there, back over An Slugan and pop into the trails of Badaguish to finish. Nice loop for 5 – 6 hours.
Or if the weather is glorious, ride up the main track onto Cairngorm, head along above the northern corries and return via the waterbar descent to the main ski car park or keep heading down to Glenmore if you start from there. The off road descent is ace. Not technical but great fun. If the weather is gash, I wouldn’t recommend the Cairngorm option but on a good day, it’s ace!
Or play round Rothiemurchus then do an out and back on the Lairig Ghru.
All good!
Or up the Burma road then at the top return via the singletrack descent through Alvie Estate. You could then do a ride and push up onto Craigellachie – which is lovely!
Cheers
