Nice trail near Longmont, not too busy. Great for four-legged friends.

Yes the trail is closed due to the flood that took out the bridge, the creek is so low that you can easily cross, and the trail goes on from there. My hiking buddy and my went straight up the mountain 1,300 ft to the top off trail and hand a wonderful time, but it was extremely difficult through all the dead trees. Not for beginner hikers. There is a campsite at the top carefully laid stones, and a full fireplace with cooking utensils and a latrine made of rocks. If you want to be off the grid before the snow comes, this is your last resort.

Perfect spot for a family hike and camp out in the wilderness. Can't wait to go back and hit the other trails in the area.
