Are there rules on having a bbq at the picnic areas? Like can we bring propane or charcoal only? Or non at all

You can bring both.

Your able to use both.. But its a good idea to have someone save a spot fir You. Very clean n good place for kids to play..

You can you use what you need for BBQ. Propane should be fine. Have to save a spit if you plan on having an event or party there.

The park has BBQs as long as you get there early, especially on holidays. Propane don't think there's a problem but not 100% on that.

Yes you can clean up after your picnic get together
