6 feet of beautiful snow fall annually on the 12 trails of Hidden Valley. This close by ski hill has a drop of 620 feet and has 4 ski lifts. Hidden Valley has 36 acres of skiable area; 47% of the trails are demanding while 58% are blue and green. Hidden Valley has magnificent trails to suit any ability. This is no spot for people who donít like to have fun. Smoke Rise Farms is a great scene to ride
horses near Charlotteburg Reservoir. And that's not all you can do here at Charlotteburg Reservoir. Charlotteburg Reservoir is nice enough to spend more than a day at, Camp Ocawasin Lodge is a nice local campground.
