Hike is rated as moderate, but only because of the distance.  There incline is slow and very gradual; total elevation gain was 1400′. The trail is mostly shaded and can get chilly later in the day. Wear layers until you warm up.  Trail is well marked and would be great for a trail run and it traveled by families, mountain bikers and is suitable for all.  We went on a Sunday around 12pm and got lucky with finding a spot in the parking lot.  Once we reached the summit, it was fun to wander around, take in the sites.  A great time of the year to hike this trail because we got enjoy the couple of months Northern California is green.
