There are 20 orienteering posts located at various positions around the site. Each has a Number and a letter on it. There are 2 identical maps available; one with all the numbers marked (1-20), and one with 20 of the letters from the alphabet marked (Missing Q, V, W, X, Y and Z). The orienteering course can be used in a number of ways. Full details can be found in the Orienteering Information section of the Downloadable Documents page.
