Great, thank you all for you replies... Very helpful. Thank you.
Yes there is parking we had a bus you'll just need to go towards the lake
There is an upper and lower parking lot that could accommodate a trailer if it isn't full of cars. This spot was very busy mid week in off season (early May).
Yes, wile entering the park, one needs to ask the ranger checking tickets.. he will assist...
There are a few lots in the very immediate area so while I didn't notice any trailer parking (also wasn't looking) I'd safely assume there is some.
