Do i have to give the 5$ donation? I would like to take my sister and girlfriend somewhere completly free cause were kinda broke at the moment

There is no charge. Totally up to you if you wish to donate or not.

Donations are not required.

It is free. Maybe next time you can leave a donation, once you see what the donations are used for. It is one of my favorite places to visit!

It's 100 percent free
