How about this one chaps...
www.greenhillsholidaypark.co.uk - a pleasant, well appointed site set in the heart of the Peak District National Park just a mile from the picturesque Derbyshire town of Bakewell.
<*>4 miles east of Chatsworth!
<*>Tent + 2 adults £19 per night inc electric hook up!
<*>Pup Tent or Gazebo £5.00 per night!
<*>Extra Adults £5.00 per night!
<*>Stable bar - dispensing a good variety of draught and bottled beers!
<*>Free hot water to showers, washbasins, and pot washing facilities and adjoining laundry room.
OK, it isn't tremendously cheap, but then again it does have some fairly decent facilities. If you want cheap, there are plenty of farmers fields.
However a lot of these camp sites do not permit a group of same sex individuals, ie all blokes in particular! I think they have had previous bad experiences with riotous stag nights, etc so that might be an issue.
To get around this, I suppose we book separately then. Unless you think it's worth just booking and see what they say. I think their minimum weekend booking is Friday 12 Noon - Sunday 12 Noon, ie two nights.
Has anybody else looked for a site or found anything more suitable?
