Wish I checked this today before I left. It is, in fact. Closed permanently due to flood damage. Talked to a ranch hand on the land that is closed. It's done for. Not recoverable

Good rocky trail for hiking, well kept with good views along the way. Even met a sizeable buck, Prarie dogs and rabbits. decided to take Bitterbrush up to the Nelson loop and then Nighthawk back. Nighthawk was a mistake. This trail is overgrown and we got caught in rain and the entire way back was a mudpit. Be very cautious of the entire hall Ranch area if there is a chance of rain or had recent rain, it will be a miserable muddy experience. In dry conditions, a great trail.

Beautiful trail! Well maintained and easy, with a little bit of everything for the senses...water, trees, wildflowers, meadows and mountain views. Hiked 4 miles in, to bridge crossing the creek, and returned the way we came. Highly recommend for a summer hike; looks like it would be a great winter snowshoe.

5/31/2014 - Lion Gulch Trailhead which leads to Homestead Meadows is closed due to the floods in 2013. There was trail work done this weekend but the middle section of the trail is still mostly destroyed.

Word to the wise: Somewhere near the highest elevation of the loop, it is very easy to get onto another trail called the Button Rock Trail. It eventually (5+ miles) gets to another trailhead called Hall Ranch, at least 10 driving miles and a few ridges away from the parking lot at Longmont Dam. I got 2 miles down this path before turning back. Never did see where the Sleepy Lion & Button Rock divergence was marked. A gate simply said "you are leaving Button Rock Preserve" with no other options.
