It was almost on our list in September, as we had a week at Darley Bridge between lockdowns. Definitely one I'd like to visit before long, I must admit I'm not a fan of trackless heather though!
Certainly takes its toll on boots.. I use heavy duty work boots with steel toecaps when out in it. Plus you have to be mindful of hidden voids in the tall stuff. I put a leg into one when fieldwalking on Burbage last year.. could sooo easily have been a break. I prefer not to do it alone now - a rattling experience.
