I already transportation figured out to Avebury, which I will be arriving at at around 1pm.
My question is whether or not it's possible to walk from Avebury to West Kennet Barrow and back before it gets dark at around 5pm?
My other question is if it's advisable that I do so, as it's January, muddy, and will probably be raining off and on?
Bear in mind I'm a fast walker/experienced hiker, so that aspect won't be of any concern.
Thanks in advance for any advice!
