A beautiful high mountain lake is the setting for this out of the way campground. Plenty of fishing in lake and streams. Good hiking and ATV trail access. Campsite facilities include picnic tables and fire rings with cooking grills. Within the campground there are vault toilets and a day use picnic area. On Bayhorse Lake campers will find a boat launch and two boat docks for use by non-motorized watercraft. This dirt road is narrow and steep and while trailers are allowed, caution is advised; best fit for trailers and motorhomes less than 32 feet long. No drinking water is on site, and please pack out your trash.
