My brother and I manage the lettings and maintenance for a charity owned bunkhouse out in the wilds of Exmoor. Have a look at the blog here: http://exmoorcentre.blogspot.co.uk/ or follow us on Twitter via @exmoorcentre or me at @willbowden
The bunkhouse is very cheap to hire and anyone can book it. It is 1km from the road down a steep valley and across a river so you do need to be reasonably fit and agile to get there. We can transport any luggage or kit you want to get out to the bunkhouse by Land Rover for a modest fee if required.
