hello sir.
Sundown's not set up for hiking with out a ticket. It's on private property, so the state parks thing doesnt apply, liability concerns are obvious, and frankly, we work our tits off and arent really into giving it away.
That said, there's price options abound. So if the 8-hour price tag scares you off, dig around, there are other ideas...
if you want more info hit me up. We love meeting new people that enjoy tooling around in mini parks.
Enjoy
