If you are looking for a great Fall hike to an alpine lake then Gibson Lake might be for you. Great fall colors on a challenging hike.
The Fall is an amazing time of year with all of the leaves changing. For my first view I checked the Fall Colors of Colorado at Kenosha Pass.
If you are going to hike at night you need a good light source. My review of the compact and rechargeable Foxelli MX200 Headlamp.
