Do NOT hike his trail in the spring time! It was covered in snow - And steep with muddy and snowy does not mix well. I hated almost every minute of this hike. The view is hardly worth it either. The pros? It's off leash if you have the Boulder voice/sight permit and it's not very crowded. Other then that, I'm struggling to think of positives. Maybe in the summer?
Great trail. I came in off the ski jump trail and hiked up to Green Mountain summit. Great views.
