I also used furlough time to get out and walk, managed about 400km over 2 months, mostly around the reservoirs and hills on woodhead pass. If you park up near the tunnels at the end of the woodhead reservoir, you can walk up to the top of the moors, and make it over to Bleaklow (easier route if you park up on Snakes Pass) to see the wreckage of the B-29 Superfortress, and the views from Higher Shelf Stones are pretty good! Also near the tunnels at Woodhead, there are a few cloughs that take some scrambling over rocks, but some hidden waterfalls can be found, and its a lot of fun. Similar can be found a few km's from the car park at Crowden, I did almost break my leg though, but fortunately had enough mobility to make my way out, otherwise a helicopter rescue would have been the only way out!
