Don't ride when wet. See the website for trail closures.
Sister Grove Park is a neat area for beginner to intermediate riders. This trail segment is an intermediate trail option of four that all start from the same trailhead; all the trails run clockwise so you begin by going left.
Lake Loop is mainly hard packed smooth dirt with about 30-40% roots that twists and turns through the trees. There is a new jump added that is not to far from the trailhead, there is also a bypass for the jump. It is a relatively short loop with a decent gradual decline which results in a pretty decent incline as well.
I didn't see any views of the lake while on the trail. There is pretty low traffic during the week - I only saw two pairs of other riders on a different trail.
