Yes open and a fantastic place to take the family for a break
Yes they're open, outdoor only. Reservation process is archaic but it works. Print out the forms from their website and email them in at least a day ahead of time. When I emailed them I gave them a day and a range of times I was interested in. They also ask for your credit card info on the form, which I was not comfortable with, so I just gave it over the phone after they confirmed the time slot.
