It can be windy and cloudy here. There are marks to find a trail in the cloud. Also on the top there is a nice area to hide from wind and rest. If not in the cloud, the view is awesome

A large and grassy mountain, in the Glyderau range. With a summit of 914 metres above sea level, Y Garn is the 10th highest of the 15 Welsh 3000s. Y Garn translates to "The Rock or The Cairn", making it a relatively common name for a mountain, resulting in this Y Garn, being one of four Y Garns in Wales, but this one is the biggest and arguable the most majestic! On a good day, the summit provides unmatched views of the North Wales coast, Snowdon and the Ogwen Valley.
