Stand at the Tower looking at London through the clearing. Go ride the big forest area on your left, between the Tower and Broadmoor/Friday Street.
Dive in to the laurels and forest when you see little ‘deer trails’. Just take pot luck. You can do loops for hours without repeating yourself, the forest is very dense so there is a lot in a small area.
Please remember this is a shared use area and there could be children/dogs/walkers about, it’s not a “trail centre”, I think we’re pretty lucky to have it.
Leith Hill is my favourite actually, because it’s a bit ad hoc and ‘natural’, but Pitch/Winterfold is where to go if you want ‘proper’ trail riding.
