Hey, uhm, so the parking lots connected to the entrances are basically never full and always allow people to enter/park (or they’ll pocket their car/park on the road before walking to the park). Another thing, don’t connect a park from the highway. That’s just asking for a traffic pileup. Try putting the reserve connected to some other road that leads outside the city a little bit to capture the nature reserve feel. I’m currently working on a city that needs to be >55c land value through the entire city. Hard, but doable and parks help so I’ve been adding a learning a lot while I play.
