If you're planning to ride this route from south to north after autumn, be prepared for a wet experience—especially on a rainy day. The summit offers stunning, open views, but you'll need to tackle large, deep puddles that will likely leave your feet soaked. On the descent, expect a tricky combination of slick, leaf-covered rocks and a stream of water flowing down the trail, if heavy rain. It's a technical challenge, and even walking your bike can be risky on the slippery terrain.

Stunning views towards Snowdonia and lovely easy double track riding through the remote Hiraethog. The only people you are likely to meet are those that live and work on the remote hill farms here.
