These federal parks along the Current River are national treasures. I had a great time here tonight.
Typical National Park campground, the parking pads aren't even close to level, the roads are very rough, but they're amazingly low cost and you are in a spectacular place! This is the place you go when you know the main part of the park will be full by 11. At the east end of gorgeous Two Medicine Lake, spectacular mountains all around.
Keyhole State Park covers quite an extensive corner of the Keyhole Reservoir, and there are 6-ish separate campgrounds. The main road is paved, but the campground roads are gravel, leading me to deduce that the bigger the loop, the more gravel dust will cover you as the diesel trucks go round and round. So I am at Arch Rock Campground, the first loop and one of the smallest. Also, no boat ramp means fewer trucks.
The real name of this place is Samuel Buckland Campground, but it's easier to just call it the campground at Fort Churchill. The terrain is barren high desert hills for miles, except for this lovely belt of ancient cottonwoods along the Walker River.
Due west of Chico, about 12 miles on the west side of I-5 is Black Butte Lake. There are two ACE campgrounds. This one is the main one, with a nature preserve and large recreation area. Open all year, on a point of land jutting into the lake, quite scenic. This campground is closer to the lake.
