There is a trailhead at Siena Reservoir so that no surface road riding is necessary. There's no shade on the trail, but lots of picnic sites with shaded tables for resting.

it was pretty cold today. 33 degrees. The pond was frozen but there were still a few of us getting a walk in before the playoffs started . It's a clean, convenient little Park when you want something close to home.

FYI. People on this trail don't seem to leash their dogs.

Still snow covered on half the loop around the lake but was easy to complete in just running shoes.

Beautiful, simple, leisurely stroll on a beautiful December day. Can’t ask for a better place to ground and reflect.

Dog & kid friendly but not much to look at considering it’s in between two busy streets. Easy place to take a walk.

Gentle, user-friendly Trail. Nice that it's so close to home. It will be even more beautiful when some of the smaller trees get big.

Very nice trail for an easy walk around the lake. It’s well maintained with a few picnic tables/ shade areas around the lake to rest or enjoy the scenery. There is also a larger picnic area with restrooms at the east end of the lake.

Walking

On the day my two dogs and I visited (4/7/19), there were very few people/dogs here. Even though the park is surrounded by roads and cars, we enjoyed the peaceful walk around the reservoir. Half the trail is paved and the other half is dirt. Several pavilions, trash cans and benches around the park as well as shade. Very clean place.
