Iron Glaiden is the treed triangle between the upper pitches of Devil's Club and the first switchbacks of The Last Spike.
These glades are often good fun, particularly during the first half of the season, if you're looking for a good challenge in the trees.
Glading work this past summer (2015) has further enhanced these few steep pitches.
Make sure to exit the glades on the Ninja Traverse to get back to the Stoke Chair, or go left and onto Devil's Club.
The trees below this point are not well spaced and too close to be fun.
