Hamsterley is easy to get to and well signposted from the A68 at Witton-Le-Wear
At this time of year we normally ride a mixture of the red and black routes that links up the best bits and avoids the worst of the boggy stuff. There is nothing too gnar on the black.
A leisurely lap of this route will take most people under 2 hours,there are of course sections you can session. Another option is to do 2 laps.
I’m fairly sure that the tearooms at the main car park were closing last time I was there (Nov)- they were neither great or bike friendly. A better option might be to pop in and see Joe at the Descend Hamsterley cabin – he does a cracking cuppa. The Mechanics hut beside the DH track is also much better than the main forest bike shop. handily these are 2/3rds of the way around just after the longest of the climbs
I’m not sure where I’d stay… Durham would be okay if you wanted a night out.
