The one outdoor activity spot in Bovenkarspel is not free — it charges for entry. Free entry is tagged on a card the moment a venue offers it, so this answer changes with the data rather than with an edit, and the listing links through to the venue's own prices.
The one outdoor activity spot here has not published its facilities yet, so we cannot say. The listing links straight through to the venue's own page and phone number, which is the reliable answer for a question this specific — and we add the facilities to a card as soon as a venue tells us.
