There are 3 Army Cadet Exchanges under the same umbrella: Outward Bound - Scotland, Outward Bound - Wales, and Maple Leaf Exchange. All three do basically the same things, which includes field training, section tactics with the Cadet GP and webbing, hiking with combats, webbing, rucksack, and rifle, field exercises that include the former, and a lot of other stuff.
When I did OBS, We stayed at Barry Bodden(Scotland), Warcop(England), Dingwall(Scotland[Highlands]), and Crowbrough(England). We met up with the other two GB exchanges in Crowbrough and we spent a day unsupervised in London with all day subway passes(us OBS kids toured like 3 times a week when we were training and also spent a full week touring on top of that. The whole wandering around places unsupervised for many hours happened every touring day. However, Edinburgh, Glasgow, London, and Ottawa(During Canada Day) were the longest times spent in one place(we got there in the morning and had to be at pick-up at around 9 or 10) wandering around. Good times to be had.
