If you weren’t a Greenbelt resident and you did go on the weekdays how much would a pass cost? And what age would qualify as an adult?

I think the daily admission for an adult non-resident is $6. There is a 6 pass card for 5 times the daily rate. And there is a summer and a yearly rate. I am not sure when the switch over for child to adult. I think senor starts at 62. Be advised that you have to be a resident, or a pass holder to get in on the weekend and holidays during the summer.
