Hi Gooner, High Lodge offers 4 cycle trails of varying difficulty, from the green route (family) through to blue (moderate) (they managed to find a few hills on this one but it's VERY easy riding). Then to the non-walkers ones, the red ((11 miles) this is more like it – man made low berms in fast flowing singletrack plus short bits of North Shore and jumps (all avoidable if you prefer) then finally the black route (10 miles) which has bomb holes, loads of singletrack and is really good fun.
The parking seems dear (£9.60 a day) but at the end of the day you'll think it was worth it. If you intend going back in your week you can get a cheaper ticket anyway. Good cafe and lots of other activities to do.
If you don't fancy that just play in Thetford forest and find the singletrack ! HAVE FUN ! HIGH LODGE PHONE 01842815434. And no – I don't work for them I was just there a couple of weeks back – in the summer week !!
