On the way in, take the obvious climbing landie track on your right after a wee water splash (NH982865). That gives you a bit of height and a great view of Braeriach.
You’ll likely get wet feet crossing the Beanaidh Bheag but you can usually cycle through it.
The Loch is further away than you think when you first see it.
Don’t bother trying to take the path round the West side of the loch unless you like carrying your bike.
Follow the lower track all the way out (avoiding the high landie track)
Watch out for “the corner of certain doom” where a wee landslip washed away the track and there’s now a bit of maneuvering required. There’s been a couple of falls there that have resulted in hospitalisation.
