thread Tyndrum?
I haven;t done those two. A bit boggy by reputation.
permalink there's a couple of miles of slow bog hopping through the woods
so I wouldn't want to do on a wet day, but it's nothing a stout pair of boots and a depth-gauging-stick can't handle and otherwise a pretty easy duo. You can see pretty much every other top south of the great glen from the summit, would recommend

the trail follows lots of nice pools and waterfalls up the hill, so excellent for a scorcher like yesterday
