17 Forbidden Valleys in the UK You're Not Allowed to Enter

There are seventeen valleys in the United Kingdom where the wind still shelters, the water still runs, and you are not permitted to go in. From an evacuated Wiltshire village frozen since 1943 to the Scottish loch where Britain's nuclear warheads are stored under armed guard, this is a journey through the most restricted, forbidden, and quietly guarded valleys in the country — military ranges, nuclear sites, chemical weapons ground, and ghost villages that were never allowed to come home. Sit back, and let an old man tell you what's hiding behind the fences. 🔔 Subscribe for more forgotten, hidden, and forbidden corners of the UK. ⏱️ TIMESTAMPS 00:00 – Introduction 00:52 – #17 Longtown Defence Munitions, Cumbria 02:55 – #16 Warcop Training Area, Eden Valley 04:41 – #15 Castlemartin Range, Pembrokeshire 06:31 – #14 Sennybridge Training Area, Brecon Beacons 08:17 – #13 Okehampton & Willsworthy Ranges, Dartmoor 10:04 – #12 Cape Wrath Training Area, Sutherland 11:40 – #11 Glen Fruin & Garelochhead, Argyll 13:20 – #10 Redesdale Valley, Otterburn, Northumberland 15:01 – #9 Nancekuke, Portreath, Cornwall 16:36 – #8 Kennet Valley, AWE Aldermaston & Burghfield 18:30 – #7 Trawsfynydd Valley, Snowdonia 20:10 – #6 Spadeadam, Cumbria 21:45 – #5 Kirkcudbright & Dundrennan, Solway Coast 23:34 – #4 Tyneham Valley, Dorset 25:09 – #3 Imber Valley, Salisbury Plain 26:50 – #2 Glen Douglas, Argyll 28:24 – #1 Loch Long & RNAD Coulport, Argyll 30:10 – Closing thoughts Chapters and further reading on each location can be found through the National Archives, the Ministry of Defence's own public access guides, and the Nuclear Information Service — all worth a look if any of these seventeen valleys catch your curiosity. #ForgottenBritain #ForbiddenPlaces #UKHistory
