I hiked Bluff Knoll at the beginning of winter. When we started at the bottom, it was bearably cold. Though, as advised by my friends who had done the hike before, I was wearing four layers of clothes! About half-way through the hike, it got really hot and I found myself shedding down to just one layer of clothing, but not long after that it got cold, extremely cold, and the higher we got, the colder we got. I soon began wishing that I had even more layers.
It took us roughly two hours to the top and probably three hours to get down, in total a four-five hour hike.
The terrain changed often. Switching from steep steps, too loose rocks and dirt paths, therefore the hike is unsuitable for those unsteady on their feet. The weather changes as often as the terrain and you have to have enough food and water and clothing to protect yourself from this unpredictable environment.
