Martinshaw is under water and will be for some time. They have also decided to manage fell a lot of it, so it’s a proper mess.
Swithland might not be ideal for a beginner but you’ll enjoy it.
Rule of thumb for the Charnwood area is look for green bits on the OS Map to explore but don’t be surprised if you get an earful from one of the people who think they own the Country side. (horse and houndy types) Observe the Cheeky Ethics and you’ll be fine (ish)
Hicks Lodge is by far your best bet for a young un!
My eldest (6 now) took a big tumble there last summer, bit scratched up but nowt that bad, he was fine.
Going to take my youngest (4) there soon.
