This is a central location with many fine off road routes to suit all types of off road drivers, and local authorities which actively encourage the use of a variety of lanes which cater to the most extreme drivers through to novices alike, and most of the lanes have wardens patrolling them to check for illegal activity and vehicles, but are welcoming to genuine off road drivers; and will often stop and "have a minute" with you and advise on the conditions of lanes.
Peak district is a national park and offers a range of activities not just for off road driving, but many forms of outdoor activities for all the family, and many attractions for all types of people; so you can take the family along for a weekend or a few days; and being fairly central its attractive for groups of friends around the country to meet up, and its central locations means it attracts many club meets.
Hospitality ranges from very basic campsites with basic facilities through to fully equipped caravan and camp sites with all the bells and whistles, and at a variety of prices to suit all budgets; alternatively there are a fine range of B&B's with varying prices and specifications, and for the more affluent there are a variety of hotels at a range of prices. Many small villages exist with some fine scenery and local pubs which have some fine food for those willing to explore a little more, and a range of very narrow roads for those willing to explore the lanes without actually going off road. Many surprises exist for those willing to get away from the main routes and take the back lanes. How often can you turn a corner and come across a field of Llama's or camels, yes the Peak District has these.
Eating out is never a problem as facilities range from small local cafes through to decent restaurants at a range of prices; alternatively you could have supermarket fare as all the major supermarkets have large numbers of well located stores so you can stock up with food without having to carry it with you, and many with fuel which varies in price with local promotions. Many smallholdings and farmers markets as well as farms selling produce direct to customers still exist so you can get fresh food also if you want it.
Off road routes vary in type and style and with a careful planning strategy you can have a full days driving with minimal road driving, so for me its worth a visit at least once for off road driving and the wealth of attractions it offers visitors.
