White Horse Lake / campground is simply awesome.  The road in can be a little rough at times but is generally ok.  The campgrounds are well laid out, the spacing is pretty good.  The restrooms are always clean.  There can be loud music in the evenings but that goes with the territory of campgrounds.  

There is a lot to do here, fishing, kayaking/canoeing, lots and lots of hiking.    You can hike to the edge of Sycamore Canyon by following the trails that lead NW from the lake.  This is an easy hike and would be great for all ages.  Sycamore Falls just NW of the lake is a great hike, one of my favorites.  Especially when the water is running with force.

There are generally activities planned by the rangers - all in all a great place to spend a few days.
