You have to have cave certification to dive. There are plenty of divers there on weekend. I would only cave dive with someone I trusted. The park is well maintain.
Wellllll I free dove in the Devils ear and there was about 6 scubas in a pow-wow In there and atleast 3-4 more entertaining about every 15 minutes so I sure you could find a buddy if your shy just make a cardboard sign for when you get there to the visitor center saying "need dive buddy : )))"
There is an information center and many people dive there, it's also a very popular college break spot, so be aware of that as well.
Yes ask up front or better yet call before you go just to make sure.
Most likely
Yes it is ! There have a information center .
Id say sure
