In terms of the driving days, Bovington Camp has been nicknamed "The British Nurburgring" due to its 3-mile track with huge high speed straights and elevated areas. There is also a brilliant uphill and downhill straight.
Facilities are basic but include portaloos, a burger van and a sign on trailer. Make sure you dress appropriately for the weather as there is no shelter for spectators.
Bovington Camp is a military base so security is high. You will need to make sure you have all of the relevant paperwork when you arrive as well as following any pre-travel instructions you receive by email.
The address is Bovington Camp, Tout Hill, Wareham, BH20 7PJ but for directions you should be able to find 'Bovington Camp' on most sat nav devices.
