Grote Knip is a challenging dive spot in that there are many steps to carry gear down and then it is a looong swim out the reef. The beach was busy even though the bar/restaurant was closed while we were there. So no charge for access but no baths rooms or dunk tanks either. There is chair rental when they are open at $4. Very pretty beach with high cliffs surrounding the beach for a very calm ocean. No surf or current to speak of inside the cove. Barracuda, eels, crab, lobster here hanging out while we were there. Like the beach very much but the swim out and stairs left a little to be desired.
