Trail is ~8.5 miles, 19k steps, 3+ hours all the way around the reservoir. Well defined trail for the majority of the loop. The scenery is nice, water is clean, and it is not insanely crowded. It's full of wildlife. While hiking, heard a bunch of coyotes, inviting me for a feast.

Although it's not very high in elevation, 571-foot (174Β m) Peppercorn Hill still offers very nice views over the conservation area of the same name. The best views near the summit are sometimes accompanied by a bit of road noise, but it feels much quieter when you're down in the valley below.

The Kelly Property in Peppercorn Hill Conservation Area is actually divided into four distinct parcels, but they all lie fairly close to each other. All together, they are made up of wetlands, mature upland forest, and some nice rocky outcroppings that give you great views.
