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.
