It's daddy's favorite site so much that the kids are getting tired of going even though they do have fun.
It is 1st come 1st serve except for the group as site.
Unless your showing up late Friday or Saturday usually spots are available. Last two times I've been the whole park is full even the primitive site.
You'll get cell service on the upper loop.
None on the lower but it seems to be the best area for family with little ones as it's easier to ride bikes around.
