Hiking in Winter
This is a fantastic winter hike. Though significantly less popular in winter months, it is still very well traveled. Even during warm times, the well traveled trail often results in packed down ice and snow. Winter traction is highly recommended. Microspikes are your best option here. Slipping and falling on this trail is extremely common due to the icy conditions and many unprepared hikers. A little extra traction will go a long way.
