Been going here for years. Much more peaceful and well maintained than a public park. Great music program on Tuesday nights in summer. ( free for members small fee for nonmembers)
A membership is worth the cost if you plan on going occasionally plus you can take others with you.
Someone's review mentioned no hours posted for the Emergent Tower or Canopy Walk. You need tickets for those (additional charge) , they ask you when you go thru the entrance gate if you want them so not sure how they planned on going with no tickets(?)
