If you're looking for a short outing in the British countryside then Curbar Edge is the place for you.
Just a brisk 10-minute walk from the designated parking area, Curbar Edge provides spectacular views of interesting rock features scattered along the escarpment and as a result, lots of overhangs to explore. You can also see Chatsworth Park in the south on a clear day. It is also a popular place for rock climbers and dog walkers. I personally would keep my dog on a leash, from fear of falling, but many people let their animals run free, children would also need supervision at all times.
If you struggle with walking or don't find it particularly fun, Curbar Edge gives all the benefits of a long hard hike but without the effort. However, you can make it a 6.5-mile walk by including the Froggatt Edge Walk.
