HikingClosed

Wanted to get a quick hike after the Bronco game. Got there at 3:45 as the gate was being locked. Big sign saying closed for wild fires. Don't know if it's fully closed or not.

Got of work early so decided to go for a short hike/run. this was the perfect distance to get in and out quickly. It was not very crowded at all around 4pm on Monday. Saw one person on my way out and two on the way back. Will definitely do again! My only complaint is that it is not dog friendly.

Nice, easy hike even for kids. It is an out-and-back trail that is all uphill on the way out, but not very steep. Saw several deer and turkeys right off the trail. Nice views of Heil Valley from the quarry remains at the top.

It was a nice hike, but the trail was shorter than said and was slightly anticlimactic. Very pretty views though and a good trail!

I would say this trail should be rated as easy, not moderate. Not much incline and nothing technical. It was a beautiful hike, some wildflowers are starting to bloom. I went in the early evening (around 6pm) and there was hardly anyone there. Ran into a couple of friendly horseback riders. Can’t wait to come back

First to Review

Completely snow covered on 2/9, no ice or mud. Saw some folks with snowshoes; we got by with spikes, which weren't even really needed. Some forestry equipment visible along the way. For all the comments on other trails in HVR: the trail closures are only Monday - Friday until 2/28.
