The fine rainbow mist surrounding the unusually named Water-break-its-neck waterfall creates a humid micro-climate in this lush green gorge. There's a high and low path so you can enjoy both viewpoints.

Located close to the Anglo-Welsh border and skirted by Offa's Dyke, this enchanting wooded hill is dominated by larch and Douglas fir, planted in the 1950s to replenish timber stores in Britain after WWII. There's a wealth of trails and forest roads to explore on foot. It's an enjoyable place to visit at any time of year, but in the autumn the initials 'ER' appear on the wooded slopes, an arrangement planted in 1953 to celebrate Queen Elizabeth's coronation.
