When they say 'natural' they mean 'naturist': at this low-key, chilled-out mini-resort, clothing is not required. There's a variety of lodgings, including a comfortable safari tent if you really want to get back to nature. Just to show that the naturist movement isn't only about nudity, the place operates on solar power and recycles its gray water.
The Natural is located about 1km north of Sint Willibrordus, on the road to San Sebastian. Adults only.
