Very mild trail, but can do a little rock climbing at 'rocky point' (the end of the trail). There is an upper trail that leads back to the picnic sites that is a good moderate hike if you take it coming back to the parking area / trailhead.

Trail still clear. Very quiet space. I imagine the place is better when the reservoir is full.

Great place. Take the paved road in from Boulder or you're on a winding dirt road for a long time.

Quick easy trail along the reservoir. The trail stopped abruptly leaving us wanting more

I'm giving this only three stars for two reasons.

1) there is SO MUCH broken glass on this trail, it is absolutely absurd.
2) parts of it are not very well marked and it just ends all of a sudden with no marking. You kind of have to figure it out.

Besides that, walking along the lake was beautiful. We arrived early in the day and got a beach to ourselves (as you walk by, there are about four or so beaches you can walk down to with sand) and our dogs enjoyed a nice swim. The lake is tranquil and really not a whole lot of people here, which was nice. There is a large beach closer to the dam where people were picnicking and families were getting outside. It was getting a lot more crowded when we left around noon. But on our way back into Boulder we knew that this was the side of the mountain to be on -- winding back down flagstaff road was SUPER crowded. We are coming back for Walker Ranch and maybe a dip in the Gross reservoir!
