Second all the above – a really great route just as it is. A little bit of everything in it.
Did it on Sunday though, and have to mention that the path is partially blocked just before you get to Ossian's Folly by fallen trees. FC have officially shut the path around that area, but you don't know until it's too far to turn back. You can clamber over the fallen trees (as I did), but might not be brilliant with little ones or less adventurous partners!
Glen Garr singletrack is as clear of overhanging bracken as it ever has been – a great run, and fairly dry as of Sunday.
