Torrent Walk Bunkhouse in Dolgellau, Snowdonia has a few surprises for its guests. Not only does it have one of the prettiest riverside circular walks (Torrent Walk) literally on the doorstep, part of the walk is under the Mach Loop.
The Mach Loop is a set of valleys, situated between Dolgellau in the north, and Machynlleth in the south (and from which the Mach Loop gets its name), which are regularly used for low level flight training, with flying as low as 250 feet (76 metres) from the nearest terrain. What better two reasons do you need to rest your head at Torrent Walk Bunkhouse for a night or two.
