Explanation of colour courses

  • White are very easy with all controls on paths. They are mainly used by 6-10 year olds and family groups.
  • Yellow use simple linear features like paths, walls and streams. They are mainly used by under 12’s and family groups.
  • Orange progress to basic use of the compass and route choice. They are ideal for novice adults or experienced youngsters.
  • Light Green are ideal for improvers as the navigational difficulty begins to increase and uses simple contours and point features.
  • Green are used mostly by experienced under 18’s and adults wanting a short but challenging course with a very hard navigational difficulty.
  • Blue are a longer, more physically demanding course in comparison to the green. The distances are more varied between controls and the course attracts experienced orienteers.
  • Brown & Black are very physically demanding and have a very hard navigational difficulty. They are for experienced orienteers only.
  • Score means visiting as many controls as possible in any order in a specific time, like 45mins.

Terrain Description

Map is at 1:7500, 5m contour interval. Mapped by Peel Land Surveys February 2022 and updated by David Kingdon April 2023. 

This will be the first open event held using this map (it was used for Saxons anniversary event last year); the area was previously mapped as East Ashdown about 25 years ago. Typical Ashdown Forest terrain but on the lower slopes of the Forest, so there is much less open marsh and heathland than on some other areas of the Forest. 


There will be no toilet facilities at the car park or at the event. The nearest public toilets are at Crowborough Leisure Centre or at Waitrose, Crowborough.
