Planning on going during Memorial day weekend in a couple of weeks. Is it hard to find with a gps? Also is the fee just like a state park? Or do you pay to go on the tour?

State park fee. No additional charges. Yes, an updated Navigation unit easily could navigate the route.

Not hard to find at all. Its a 10 buck pass per car

Easy to find and passport on ur plate should work. No additional fees

State park fee or passport on your plate... No other fees. Easy to find, GPS not really needed...

GPS works fine. Also if you have the State Park passport you're golden.

Doesn't cost a dime, easy to find with a GPS

No problem finding it with GPS. Fee is the same as the state parks. If you have the passport on your license plate (vehicle registration). There is no fee to go on the ferry across the spring.
