There is a small fee (6-10 guilders cash) to pay at the entrance to Landhuis San Juan, which gives you access to three private beaches and this cinematic dry lakebed.
It is sometimes very dry, though it can be a bit muddy, but provides some artistic and unique opportunities. The road is very rough and branches off to different beaches. This location is to the left each time it branches off, and is about a kilometer in.
