Yes. There is a cost to enter park. 3-4 dollars per person. Depends on city resident or not. If you bring boat, then it is just a 10 dollar launch fee, no limit on people, plus you can park boat on beach and use grounds for swimming, cookout, etc. You can also launch on north end dock, still 10 dollars, and can go to sandy, use park for free. There is another beach, Bartels beach you can swim for free on the east side, has tables, play area, and swim area. You can park boat there also. Rock is a great lake. I am there almost every weekend boating. This should answer any questions.
Actually there is a 5 dollar cost for entrance or you can by a family pass for 30.00 that is good for all season. This beach is very crowded during the day but after 6 pm then it relaxs and then there is no longer an entrance charge.
No cost $$$, only need be carfully because do not lifeguard on turn!!!!
No cost to go in and swim l. There is a cost to launch your boat though. When we went there was a sign posted warning about swimmers itch so be carefull.
