Lighthouse Museum in Brindleton Bay

Not just a park...a national park. Sorry I typed 'natural' not 'national' above...fingers have minds of their own. That's the vacation destination style lots. And as far as I know you can use them without having granite falls and salvadorado, GF shipped with one as well so it is a base game lot type i think.

LOL, but as for your question, I have had sims vacation in just regular parks too. A tent is always one of the first things I get a sim family.
