You don't want to arrive after dark. There are no lights, there are just a few spots to pull into and most likely filled by early arrivers.

No, the parking area was not well lit as of the last time we were there.

I do not remember lighting but the parking lot is pretty large.

We were there in October '21 for one night. The place was closed, campground spots could be used (no facilities). I do not know if the was light. If you do not want the campground spot you always can park in front of the store.

I do not remember a lot of lights but it depends on how crowded the lot is and the size of your rig. There are 4 sites that are clearly marked and pull through as you turn into the lot.
